1504PEI_1 1 4/8/15 10:34 AM

Five years ago, Kansai Electric Power

Company (KEPCO) started a large

scale project to replace Himeji

No.2 thermal power station with

the worlds most effcient combined

cycle plant featuring a record-

breaking gas turbine with 1600C turbine inlet

temperature.

This environmentally-friendly project

targeted a reduction of greenhouse gas

emissions while securing a competitive power

supply to support the Kansai area.

The new Himeji No.2 power station is a state-

of-the-art combined cycle plant composed of

six single-shaft blocks rated 486.5 MW (at 4C)

each, for a total of 2919 MW.

Each block consists of one Mitsubishi

Hitachi Power Systems M501J gas turbine,

rigidly coupled to a single reheat steam

turbine called SRT-50, featuring 50-inch last-

stage blades.

M501J was introduced in 2009 and its

validation started in February 2011 at MHPS

T-point verifcation plant.

This steam-cooled gas turbine operates

at the unprecedented turbine inlet

temperature of 1600C and a pressure ratio

of 23:1, featuring simple and combined cycle

effciency in excess of 40 per cent and 60 per

cent respectively.

This modern plant replaced Kansai

Electrics existing Himeji power station, which

had supplied power to the Kansai region since

1963 and, at 2550 MW, was the companys

largest thermal power station a title now held

by the new Himeji No. 2.

The old plant was composed of six

conventional units that were originally

commissioned and operated with crude or

heavy oil, and later converted to natural gas.

Two of the original units are still in operation.

The 1600C turbine inlet temperature

gas turbine facilitates a combined cycle net

effciency in excess of 60 per cent, and all six

blocks have started commercial operation

with high reliability and superior performance

the last unit was declared commercial on

March 25.

In order to help mitigate the current energy

shortage, the construction and commissioning

schedule of this plant was carefully modifed

to expedite the commercial operation

date (COD) of each unit from its original

schedule.

The original plan contemplated the

decommissioning of the existing units fve and

six prior to the installation of the new units four

to six.

However, due to the impact of the Great

East Japan Earthquake in March 2011 on the

electricity system, the removal of the existing

units fve and six was postponed until earlier

this year.

The new units four through six were

constructed in the area made available by

the removal of units one through three. This

simultaneous removal and construction,

combined with the large scale of the

project in a somewhat congested industrial

area, involved very complex planning and

execution.

Existing facilities, especially the water

intake/discharge infrastructure, were used by

both the existing and new units.

Close communication and co-operation of

several teams involving mechanical, electrical,

I&C, and other departments was successful

in preventing unintended interference with

connecting piping and many other major

activities in the existing and new units.

The power station was erected on

flled ground, which raised concerns of

liquefaction, especially during eventual

future earthquakes.

In order to prevent this, the foundation

work was based on the sand compaction

pile method, with high bearing capacity piles

used to strengthen the support of the bearing

layer.

Vibration measurements were performed

during construction to prevent vibration-

induced trips of the existing units. Industrial

waste, like clinker ash and fy ash from KEPCOs

only coal-fred plant, was effectively utilized to

reduce waste and minimize environmental

effects.

The clinker ash was used for foundation

improvement and the fy ash was mixed in

concrete.

Several existing portions of the plant,

such as cooling water intake and seawater

desalination, were effectively refurbished and

will continue to operate during the life of the

new plant.

Himeji No. 2 was conceived prior to the

earthquake and tsunami that hit Japan

in March 2011. In an effort to alleviate the

diffcult power supply situation in the Kansai

area, KEPCO and its suppliers initiated an

aggressive acceleration programme that

expedited the COD of the frst four units by two

to four months.

This effort is especially important during the

high demand summer/winter peak.

Steam turbine innovation

The state-of-the-art SRT 50 steam turbine

was designed to operate with a condenser

vacuum of 96.3 kPa and features 50-inch

(127-cm) steel blades that result in large

annular area for high effciency and large

capacity.

This new large-capacity single-casing

reheat turbine features other advanced

technologies such as a high-effciency

reaction blade, welded rotor, advanced seals

and high performance bearings developed to

achieve higher effciency and more compact

design.

The down fow exhaust enables compact

installation of the condenser on the second

foor level while the turbine casing is located

on the third foor. This confguration fts the

confned space and reduces the construction

costs. Higher pressure recovery in the exhaust

hood, as well as higher performance, are

additional advantages. The turbine facilitates

the connection to the GT and generator in

single shaft arrangement with a rigid coupling

system.

Bottoming cycle equipment

This plant includes several advanced features

in the bottoming cycle worth mentioning.

Based on Kansai Electrics long-term thermal

power station operating experience, piping

support without penetration into the pipe

insulation was applied to avoid rainwater

intrusion and prevent outside corrosion.

Stainless steel tubes were used internally

in the HRSG for durability under steam

temperature in excess of 600C.

Community impact

The city of Himeji is famous for its UNESCO

world heritage Japanese castle.

Special attention was placed on the

architecture of the plant in order to minimize

its visual effect on the landscape of the city.

Ivory and beige were selected as base

colours for the faade to maintain harmony

with the outer wall of Himeji castle, and green

paint was selected for HRSGs and transformers

to refect the image of the Harima plain feld

surrounded by greenery.

In order to prevent traffc congestion

during construction, special measures were

applied to the roads surrounding the power

station. Truck traffc from/to the site for the

transportation of construction material and

equipment was shifted away from the typical

commuting time.

Special considerations were put in place to

diminish noise and vibration levels to reduce

disturbance to the surrounding community.

Marine transportation of large components

was maximized to minimize blockage of land

routes surrounding and accessing the plant.

Cleaning of public areas surrounding the

site, especially roads, riverbank and seashore,

has been routinely performed by the project

team.

The high effciency of the new plant has

enabled reductions of about 30 per cent for

CO2 and 85 per cent for NOx compared with

the original plant.

The ecological impact of the plant on

the bay ecosystem is substantially reduced

by lowering the amount of warm water

discharge by approximately 40 per cent.

Turbomachinery


Christopher Antes, head of Turbomachinery at MAN Diesel & Turbo, talks to PEi about the latest trends turbine manufacturers are witnessing, emissions control and European energy policies

Drivers of change

PEi: What policy decisions from governments

would stimulate your sector in Europe and

elsewhere?

A: In general, electricity prices are at a low

level, which favours old and outdated power

plants that use fossil fuels such as coal. On the

other hand, though, high amounts of funding

are being put into the expansion of renewable

electricity generation in many countries.

Here in Germany the energy revolution

or Energiewende is a prime example. We

already have so much fuctuating solar

and, above all, wind power in the grid that

its capacity is exceeded on productive

days and planned massive power lines and

storage options are currently the subject of

heated public debate. The need now is not

for further expansion but for mastery of the

situation. When wind turbines have to be

switched off because of overcapacity, this is

of no help to anyone. In our view, small gas

power plants make particular sense. As they

are decentralized, they are in a position to

stabilize the grid very quickly. And if they are

realized as CHP plants, they have compelling

effciency levels of over 80 per cent. Natural

gas is also a comparatively low-emission fuel.

However, investment incentives have been

reduced rather than increased for precisely

these types of plant. As a member of the

Association of German Machinery and Plant

Manufacturers (VDMA) we supported its calls

for a general shift of policy in Germany towards

decentralized CHP. The current statements

of some of our politicians calling for a move

away from the target of 25 per cent CHP share

of the German energy market in 2020 is a

bad sign for effcient and easily controllable

decentralized power plants. We are therefore

hoping for a rethink.

I have quoted this example because

Germany, with its ambition of an energy

revolution, is under global scrutiny. We are

seeking dialogue with politicians and very

much hope that our proposed solutions will

be heard. The right technology exists. Only if

the Energiewende works with us can it set an

example worldwide. And that would help not

only our sector but others too.

PEi: Which region of the world currently offers

the most turbomachinery potential for MAN

Diesel & Turbo? And why?

A: There is more than one answer to this

question. In the US the shale gas boom has

tapped undreamt-of reserves and stimulated

the natural gas market worldwide. In Asia and

Africa, efforts are being made to generate

electricity more effciently and more cleanly.

This has not, however, produced a clearly

identifable focus of activity for us. Our

range of turbomachinery products includes

compressors and expanders for the oil, gas

and process industries as well as steam

turbines up to 160 MW and gas turbines up to

13 MW. We supply turbines as a drive solution

for our compressors. This performance range

is also suitable for decentralized industrial

power generation where we can serve various

small types of plants such as cogeneration,

waste incineration and biomass as well as

combined-cycle. Essentially, we offer solutions

for which there is worldwide potential. What

this means in practice is that we tend to

identify trends for particular regions in terms of

the type of power plant.

PEi: Can you illustrate this with examples?

Up to now the UK has exported and disposed

of a large proportion of its waste abroad. The

country is now building up its national waste

incineration capacities and therefore creating

new projects. Here we are currently supplying

the complete turbine generator set for the

construction of the highly effcient Wilton 11

waste incineration plant in Middlesbrough.

Our DK 100/400 R condensation steam

turbine will generate up to 50 MW of electricity.

By contrast, our latest MGT series of gas

turbines is at present gaining a foothold in

the Chinese market. Four 6.9 MW MGT gas

turbines will be used in future by the Shanghai

Volkswagen Automotive Company in a

combined heat and power facility.

PEi: What is the future for gas turbines in

MANs performance category?

A: The demand for gas turbines is currently

growing globally by two to three per cent per

year. The big exception here is China. Only

recently the government decided to limit CO2

emissions by 2030 at the latest. Decentralized

CHP plants with gas turbines under 10 MW

play a crucial role here. In addition, Beijing has

recognized that solutions must be found to

combat environmental pollution, for example

heavy smog. What this means in practice

is that China is moving away from coal and

towards natural gas. The precise potential for

gas turbines cannot at present be quantifed.

However, it will be signifcantly higher than in

any other country in the world.

In the public electricity networks of many

countries in which strongly fuctuating

renewable energies such as wind and

solar power have an ever-increasing share,

compact gas turbines represent an ideal

backup solution. In addition, we foresee that

methane will play a key role worldwide in the

future as a clean energy source. According to

various studies it will be available for decades

as natural gas and can be produced today

renewably using a variety of methods.

PEi: Which current development trends are

you pursuing?

A: Firstly, procurement and, above all,

operating costs play a decisive role for

customers. And secondly, exhaust gas

standards are being tightened up in many

countries across the world. In particular,

1504PEI_7 7 4/8/15 10:34 AM


Q&Athere are stricter limits for nitrogen oxides.

As manufacturers we must comply with the

requirements of the legislators as well as those

of our customers in the latter case as far as

possible without restrictions or additional costs.

In addition to particularly high effciency levels,

one of our primary development goals was

therefore to ensure that the entire MGT gas

turbine family is both economically effcient

and environmentally friendly.

PEi: What does this mean in practice?

A: The single-digit NOx values in the load

range between 50 and 100 per cent obtained

with the MGT 6100 provide evidence that

we have achieved our goal. On our own

test stand in Oberhausen we demonstrated

levels of less than 10 ppm nitrogen oxide in

the exhaust gas in all gas turbine operating

modes between half and full power. By

comparison, the German Federal Emissions

Control Act, in its Technical Instructions on Air

Quality Control, specifes a limit of 36.5 ppm,

which corresponds to 75 mg/Nm3.

We have achieved these values with the aid

of our own combustion chamber technology

through the adaptation and optimization

of the Advanced Can Combustor (ACC),

which was developed for our long-established

THM gas turbine family. These can combustors

use premix technology, i.e., the fuel is pre-

mixed homogeneously with the combustion

air before entry into the combustion chamber.

Fuel-rich, hot strands are thereby avoided.

This results in far less nitrogen oxide being

formed in the exhaust gas without the need

for additional time-consuming and expensive

post-treatment systems. In a next step we aim

to guarantee very low nitrogen oxide values to

our customers on the basis of test results, thus

further increasing the competitiveness of the

gas turbine.

PEi: And what is your future forecast for steam

turbines?

A: We are seeing a trend towards renewable

energies, particularly in the industrialized

nations. This change entails a great deal

more than the development of photovoltaic

and wind power facilities, which is being seen

in many areas. We defnitely see ourselves

as a partner in the energy revolution, not

least because many of these types of power

plants are capable of meeting baseload

requirements and are therefore able to

contribute to the stability of power networks.

The higher the proportion of fuctuating

energy sources such as solar or wind power

in a power grid, the more important this factor

becomes.

We have supplied the 220tonne steam

turbine for the 100 MW CSP Shams 1 power

plant in Abu Dhabi, have ftted out numerous

waste incineration plants in Europe and have

been involved in the generation of electricity

from the waste heat of a smelting works in

Norway. We have equipped many regional

biomass power plants with our MARC series

of steam turbines, which were specially

developed for industrial power generation.

These require small turbo generator sets, which

we can deliver in sizes from 1.5 MW upwards.

PEi: Are you seeing increased demand for

waste-to-energy technologies, biomass and

concentrated solar power? In which regions is

this happening?

A: As already mentioned, the UK is building

up its own waste incineration capacities. These

plants are currently often realized as waste-

to-energy applications. Anywhere that waste

needs to be disposed of and is available

as a fuel source, converting it into electricity

is a logical step. The residual heat can also

be used in CHP plants, for instance to heat

neighboring industrial or residential areas. We

also see potential here in Eastern Europe, for

example in Poland.

PEi: And what about biomass?

A: We have been involved in numerous

biomass projects in Europe. German and

Austrian plant constructors have built up

their technological leadership in Europe in

this area over the last few years. A type of

formula power plant with certain standard

components has become established and

has been a real success on the export market.

For this reason we adapted at an early stage

to certain boiler sizes and developed the

MARC 1 steam turbine to be able to equip

even power plants of between 1.5 and 3 MW.

However, the number of biomass projects in

Europe is directly related to the existence of

national programmes to expand capacities

specifcally in this segment. Conditions

in Europe are currently diffcult as most

programmes have come to an end.

PEi: How do you assess the market in

emerging countries?

A: In the emerging and developing nations

the situation looks somewhat different. By 2020,

we foresee emerging markets especially in

African and Asian countries. They are building

up infrastructure and their demand for energy

is constantly growing. Small and decentralized

biomass power plants are one trend we

can see which is driven by the utilization of

agricultural waste as fuel. However, the quality

standards in these markets are different.

Locally manufactured, outdated steam

turbine technology is mainly in use here.

PEi: What future prospects do you see for

concentrated solar power?

A: In terms of building CSP plants, Spain

has up to now been the front runner. Unlike

conventional plants, a solar-powered turbine

must be designed to be started up and shut

down each day according to the availability

of the suns rays, and therefore of the steam.

However, the notable success of the Spanish

solar industry has had some major setbacks.

Both the previous and current government

have reduced solar funding with retroactive

effect. This has destroyed the confdence

of many investors. The market has therefore

moved away from Europe. Major new

installations are currently in the planning stage,

particularly in the MENA region. When the 100

MW Shams 1 plant joined the network in 2013

in Abu Dhabi, the at the time largest CSP

power plant in the world set new standards.

With 125 MW gross power, the steam turbine

we delivered was the largest ever built for a

solar thermal power plant. In Southeast Asia

and countries such as Israel, CSP is under

consideration but on a smaller scale.

China has always been

thought of as a coal

market, but increasingly

the largest nation in

the world is adding

renewables and fexible

gas turbine technology to reduce emissions

and diversify its energy portfolio.

Chinas gas power generation capacity

is expected to rise from 43.8 GW in 2013 to

85.5 GW by 2020, substantially boosting gas

turbine installations in the country. The growth

will be driven by Chinas need to adopt

cleaner fuels for power generation, including

renewables, and reduce its reliance on

coal, which accounts for 62 per cent of the

countrys total installed capacity.

Chinas gas power generation market

value stood at $652 million in 2013 and is

forecast to jump to almost $1.7 billion by 2017,

according to the analysts at consultancy

GlobalData.

At the same time, China has increased

its investment in renewables nearly every

year for the past ten years. New renewable

power capacity surpassed new fossil fuel and

nuclear capacity in China for the frst time in

2013. Chinas goal is to have 20 per cent of its

total energy demand sourced from renewable

energy by 2020.

Given the convergence of gas turbines

and renewables in China, the nations gas

turbine plants will require more fexibility. The

more renewables that are added, the more

fexibility will be required. Gas power plants

are often ramped up and down, or cycled, in

response to changes in demand and load.

The time required to ramp up and down, the

plants effciency at part load, and the overall

duration of plant output determine the fuel

consumption and economic performance of

the power plant.

Unlike baseload plants that operate

continuously, fexible power plants can

provide short-duration load, or burst load.

Burst loads are produced in response to the

sudden loss of a power generator, reduced

output from wind and solar sources, or spikes

in demand. Fast, fexible generation improves

reliability and power quality by stabilizing the

electric grid, allowing more renewables to be

added over time.

Current technical constraints

Combined cycle gas turbine (CCGT) plants

have technical constraints that affect their

startup time, ramp rate, and minimum load.

Cycling raises concerns about increased air

emissions and thermo-mechanical stress on

CCGT plant equipment.

The startup time, the time to ramp up

output to full load, the minimum available

load, and the effciency at part load determine

the amount of fuel consumed and the

length of time the plant operates each day.

By producing output during peak demand

times, the power plant is more valuable to the

grid because of its ability to balance variable

renewables.

Being able to start quickly and run at a low

minimum load will allow the plant to operate

effciently more often and meet a larger range

As China looks to fexible gas turbine technology to cut emissions and diversify its energy portfolio, Peter Perri of US-based Powerphase outlines the opportunities

Opinion: China turbine market


of demand requirements. In the modern

power grid, intelligent resources should be

able to ramp up and down as fast as possible

without risking damage to the power plant

equipment.

As more renewables are added to the

grid, shorter bursts of energy from gas

turbines are required to meet the variability

of the renewables. Shorter bursts and more

cycling decrease the effciency of CCGTs

and increase the amount of fuel per MWh

of electricity produced, increasing operating

and fuel costs. Since the effciency of gas

turbine power plants degrades at part load,

frequent starts and stops will further reduce

the overall effciency of CCGTs.

As an alternative to CCGTs, reciprocating

engines have been considered. However,

reciprocating engines cannot match the

effciency of the CCGT at baseload and

are often not viable solutions for the type of

multi-hundred MW power plants required to

meet the demand of a large electric grid like

Chinas.

Proposed solution

A CCGT equipped with Powerphases

Turbophase Flex capacity and fexibility

upgrade combines the fast start and burst

capability of a reciprocating engine with the

effciency and scalability of a CCGT.

The Turbophase Flex Enabled CCGT plant

can add megawatts to the grid in 60 seconds,

and can offer the predictability of ISO-rated

output at all ambient conditions. For example,

a nominal 569 MW 2x1 CCGT equipped

with the upgrade will produce 569 MW on a

0C day and 569 MW on a 50C day. When

comparing price, looking at the average

number of kilowatts produced throughout the

year, the Turbophase Flex Enabled CCGT will

cost less on a $/kW installed basis than the

standard OEM CCGT.

Powerphase president Bob Kraft says: As

the market begins to understand the full value

of what were offering, decision-makers will

come to view the Turbophase Flex Upgrade as

standard equipment when adding new gas

turbines to the grid.

He adds: Planners analyze capacity

additions based on cost per kW, effciency

and, increasingly, the ability to respond quickly

to load fuctuations.

When they look at a Turbophase Flex

Enabled CCGT versus a standard CCGT, they

are seeing more capacity, more effciency,

and more fexibility at a lower total cost per

kW installed. Increasingly theyre going to say,

If the cost per kW is lower, and Im getting all

these added benefts, why wouldnt I add the

upgrade?

While a typical CCGT requires about

60 minutes to reach full load, a Turbophase

Flex Enabled CCGT plant can add capacity to

the grid in 60 seconds. The rapid Turbophase

Flex start eliminates much of the need for

ineffcient low-load conditions at the CCGT

plant, reducing the overall fuel burn. It also

increases the range of output the plant can

offer to the grid, both at the low end and high

end of the range, increasing the megawatt-

hours the plant will dispatch over the course

of the year and boosting economic value.

In addition to pioneering its new

technology, Powerphase has pioneered an

innovative way to pay for its capacity and

effciency upgrade. Dubbed a Power Service

Agreement, customers who choose this

option pay one monthly fee that includes

installation, equipment, controls integration

and maintenance. The company says it

can make sense in cases where a customer

wants to avoid CAPEX expenses and would

rather see positive cash fow immediately and

throughout the contract.

Many power plant owners globally have

been considering ways to realize more value

from their assets. In real operating conditions,

megawatt-hours is one of the most important

economic considerations when evaluating

the return from a project.

China is an example of a forward-thinking

power grid that is diversifying rapidly into

renewable generation. In that context the

Turbophase Flex Upgrade is likely to see

widespread adoption in China and other

innovative markets because of its ability to

start in 60 seconds for balancing renewables,

while improving the effciency of reliability of

gas turbines.

Like many other types of rotating

equipment, steam turbines have

bearings that support the axial

and radial loads. These bearings

must be properly lubricated in order

to achieve L10 lifecycle. Turbine

bearings are exposed to high temperatures,

high transient thrust loads, long states of idle

readiness and a moisture-laden environment.

These can be seen as severe operating

conditions at best.

Of all operating environments, however, the

state of idle readiness introduces the highest

level of contamination exposure to a turbine

bearing and lube oil system. That is because

the rotor and, in most cases, the lubrication

system is in a static state, which allows live

steam leaks past the carbon shaft seals.

As the steam makes its way past the

OEM labyrinth bearing housing seals, which

function properly only in the dynamic state

(when the shaft is rotating), it condenses

on the cooler inner surfaces of the bearing

housing and collects in the sump. When the

turbine is put in service the bearings can fail

prematurely due to this moisture

contamination.

If the turbine has been idled for a very

long period of time under these conditions,

the bearings have already reached stage

fve failure on the P-F curve before the unit is

put into service. The location of the escaping

steam can be seen in the turbine cross-section

diagram of Figure 1, showing the rather simple,

stationary labyrinth isolators (in circles) which

are provided by some OEM steam turbine

manufacturers.

To overcome these issues a more advanced

labyrinth bearing protection seal has been

developed, which offers protection against the

ingress of steam and is also non-contacting in

operation. LabTecta66 incorporates patented

dynamic lift technology to protect against the

ingress of steam and other contaminants that

contribute to 52 per cent of all bearing failures.

This dynamic lift technology uses the

centrifugal force of rotating equipment

to open a temporary micro-gap allowing

expansion of the oil-air mixture in the bearing

housing, which consequently allows the

equipment to breathe. When the equipment

stops rotating the micro-gap immediately

closes, forming a perfect seal. This prevents

steam, moisture and dust being sucked back

into the bearing housing and eliminates

bearing oil contamination.

The cross-section of a

LabTecta steam turbine

labyrinth isolator is shown

in Figure 3. You can see that

this seal also utilizes two

drive o-rings, two shut-off

o-rings that seal on a smooth

surface, and easy refurbishment capability.

But the steam-turbine isolator has two unique

adaptations. First, a graphoil ring has been

placed on the side nearest the steam to help

protect the Afas o-rings from the intense heat.

Second, the design of the rotating unit has

been changed to create a steam defector

which repels the impinging steam.

LabTecta66 is also designed with a thinner

cross section and seal length than competing

devices, which means it can be retroftted on

more equipment without having to carry out

modifcations.

LabTecta66 is a labyrinth bearing seal

design that is non-contacting during

operation, and hence no wear takes place

during rotation. Therefore, a carefully specifed,

properly installed and operated non-

contacting labyrinth bearing protector can

have an infnite life expectancy.

A recent research paper produced by

AESSEAL analysed the 120,000+ LabTecta66

products that had been supplied in the eight

years since the products launch. Between

January 2006 and September 2013, only

52 of the 120,000+ LabTecta66 bearing

protector seals were removed from service.

After detailed examination, it was concluded

that any abnormality was found to be operator

based (such as mis-installation and lubricant

overflling). The research also conducted an

accelerated life test with a stop-start cycle of

four times a day, which determined that the

average LabTecta66 life expectancy was

over 10.5 years. The paper also showed that

by using an established statistical (WeiBayes)

technique, the average life expectancy was

also in excess of 10.5 years. However, because

such statistical data can only be modelled

with failure data, and as no LabTecta66 has

ever failed, the results must be viewed as

conservative.

Figure 3:LabTecta steam turbine labyrinth isolator, cross-section

A US-based producer of phosphate fertilizer

had faced an ongoing issue that, during

normal operations, steam leaking past the

carbon rings caused moisture ingress into the

bearing housings. This had been occurring

for a number of years and the engineers had

found that the OEM standard, non-contacting

labyrinth seals were not effective at preventing

steam and moisture ingress. It was calculated

that the Mean Time Between Repairs (MTBR)

for the turbines was only four to 12 months

with the OEM seals. Set against this was the

turbine rebuild cost, which could be anything

from $35,000 upwards. Several seal design

changes had been tried to improve the ability

of the OEM seals to exclude the moisture from

the bearing housings, without success.

A Reliability engineer working for the

company studied MTBRs and performed

root-cause failure analysis on a wide range of

rotating equipment failures (turbines, pumps,

gearboxes, trunions, etc), and concluded

that bearing failures were frequently caused

by lube oil contamination resulting from the

steam in the operating environment entering

the bearing housings. The companys Terry

GAF4 steam turbines were suffering from water

contamination of the bearings, leading to a

MTBR of as little as four months. This had been

a chronic problem for the last 40 years. Just

replacing the bearings on this turbine costs

$14,000. A full turbine rebuild costs about

$35,000. An emergency rebuild in August 2010

of an Elliott EPG-4 turbine and 90P single stage

compressor due to water related failure cost

over $300,000. A solution was needed to stop

this frequent and expensive damage.

To reduce moisture ingress and improve

the MTBR of the turbine bearings, a number of

GTGS will submit a full and detailed

report within 7 working days and - in

the event of any critical instrumentation

issues being found during the visit - will

immediately make you aware of the problems

and will work with you to rectify the issues.

As the engineer providing the service

and completing the work it will always

be done to the highest standard possible and

even in the unlikely event of unrelated issues

being encountered during start up following

an outage you will always receive GTGSs

full assistance to ensure the minimum delay

in returning your unit to service.

10 reasons for choosing GTGS for your generator and turbine servicing1

Most turbine shutdowns or drive

backs will be due to a field wiring

or instrumentation issues. Regular

12-monthly core engine and critical

instrument calibrations are a vital part

of reducing these unplanned and costly

events. GTGS can mobilise at short

notice to resolve the issue so you can

declare yourself commercial to the

network and reduce the lower rates that

a unit which has reliability issues tends

to attract in a peaking market.

4 GTGS can also complete Calibration checks and functional checks on

your excitation system (Brush MAVR, PRISMIC A30, PRISMIC A32).

3 GTGS will carry out an annual inspection of your DAX7-290 BRUSH generator including testing of the stator (PI), rotor, exciter and PMG, line side and neutral cubicles, shaft earthing brush and all heaters which are critical

to maintaining the health of your generator.

2 GTGS will carry out annual

calibration checks on all Pratt &

Whitney TWINPAC and SWIFTPAC

critical instrumentation, using the latest

precision DRUCK IDOS UPM system.

A full calibration sheet is produced for

each instrument detailing the device, the range, the output, the percentage

FS errors found and whether in tolerance, the HMI reading, the percentage

FS errors - again whether within tolerance.

modifcations was attempted, including tighter

running clearances of the OEM labyrinth seal;

air buffer porting; low pressure reducing baffe;

instrument air purging the oil reservoir, to

prevent ingress of moist air; nitrogen purging

the oil reservoir, to prevent ingress of moist air;

desiccant vent flters, to dry the air entering

the housing; vent check valves, to allow one-

way fow of air from the housing; and synthetic

lubricants, with improved moisture separating

qualities. However, none of these modifcations

was completely successful and they resulted

in several well-known after-market bearing

isolators being investigated and tested. Most

of these labyrinth isolators achieved some

improvement over the OEM seal, but none

fulflled all of the requirements the primary

objective being no oil leakage out, and no

water entry in.

The plants engineering team decided

to try a set of three LabTecta66ST bearing

isolators, which were installed on a Terry GAF4

turbine. The cost for these isolators was around

$2400. The results exceed expectations by

a considerable margin and the turbine

was found to be running perfectly after

24+ months. It is estimated that this initial

investment in an effective bearing protection

system has avoided at least three turbine

repairs over two years, with a total saving of

$100,000. This results in a payback period

on the initial investment of less than three

weeks, with ongoing savings of $50,000 per

year. Weekly oil samples taken from this steam

turbine continue to show zero moisture in the

oil. Turbines with LabTecta isolators that are

taken out of service for other reasons have

no corrosion and are found to be in pristine

conditions inside the bearing housings.

Steam and moisture entering the bearing

housings of steam turbines and other

rotating equipment was a major source of

costly failures at this plant. The OEM bearing

protectors were found to be inadequate for

the severe conditions surrounding steam

turbines, a common problem worldwide.

The US-based producer of phosphate

fertilizer had tried numerous housing design

and lubricant changes to eliminate or at

least minimize the effect of the water in the oil.

The engineers then investigated and tested

a number of different bearing housing seals

and isolators, before they standardized on the

modern labyrinth design shown in Figure 2 for

its pumps and gearboxes, and Figure 4 for its

steam turbines.

In conclusion, it can be seen that steam

and moisture entering bearing housings can

be prevented by modern labyrinth bearing

protectors. These are designed to operate in

the elevated temperatures and high transient

thrust loads founds in steam turbines as well

as preventing ingress during long states of

idle readiness. Labyrinth bearing protection

is therefore a highly cost effective method of

extending MTBR and optimising ROI.

To satisfy ever-increasing demands

for electricity, gas turbine power

plant managers are keen to

improve the output and reliability of

their operations. Through selecting

the right lubricant, operators can

maximize production and proftability and

reduce unscheduled downtime, which helps

increase worker safety. Varnish formation is

one factor that can have a highly detrimental

effect on gas turbine operations.

During operation, varnish deposits can

build up and stick to various interior surfaces

and block openings and flters, which can

reduce power output and reliability. To combat

this, operators should look for a turbine oil

with higher level base stocks and advanced

antioxidants which can provide protection

against oxidation when properly formulated.

While treating the symptoms of varnish

through mitigation technologies may extend

service life, the important factors for reliable

operation are starting with a clean system and

using a turbine oil designed to prevent varnish

from forming. A well-balanced oil formulation

that utilizes high-performance base stocks

and advanced technology additives is the

frst line of defence against the formation of

sludge and varnish.

To select a well-balanced gas turbine

lubricant, maintenance personnel should

consider the following performance areas:

lDeposit Control advanced turbine oils

are formulated to limit the generation of

sludge and varnish, while keeping deposits

in suspension;

lOxidation Stability higher level turbine oil

base stocks and advanced antioxidants

against oxidation;

lAir Release and Foam Control oils

formulated to have rapid air release

and minimal foam formation will provide

superior protection against the formation of

varnish;

lFilterability (the ability of an oil to pass

through a flter with minimal pressure drop)

oils with poor flterability will pollute flters

faster that those with good flterability. This

often translates into more frequent flter

changes;

lAnti-Rust and Corrosion protection oils

formulated to minimize rust and corrosion

that contribute to oxidation and the

formation of contaminant-based varnish will

reduce the likelihood of varnish formation;

lWear protection wear material from

high pressure hydraulics, the gears of

the accessory gearbox, and generator

reduction gear or turning gear can

indirectly be a source of varnish formation,

since the wear metals will act as an

oxidation catalyst.

Safety is another fundamental concern

and the number one priority for power

generation companies. Maintenance

procedures carried out during both scheduled

and unscheduled downtime have the

potential to put operators at risk through direct

contact with equipment. Advanced lubricants

can help mitigate potential injury risks and

increase overall productivity for both owners

and operators of gas and steam turbines. By

extending equipment and component life, for

example, advanced lubricants help reduce

unscheduled downtime and contribute to

reducing employees exposure to hazardous

maintenance procedures.

The balanced formulations used in the

development of Mobil industrial

lubricants are designed specifcally with

these benefts in mind. For example, Mobil

DTE 732 M can help minimize safety risks

and improve turbine reliability thanks to its

high performance features, such as:

lLong oil and flter life: the lubricants

excellent chemical and oxidation stability

help reduce maintenance downtime and

costs by contributing to system cleanliness

and deposit reduction, which can enable

long oil and flter life;

lLong equipment life: powerful protection

against rust and corrosion of critical oil

system components helps to minimize

maintenance and can promote long

component life;

lTurbine reliability: Mobil DTE 732 M

demonstrates high resistance to foaming

and rapid air release while minimizing

sludge formation potential, which can

help control maintenance downtime by

promoting reliable turbine operation.

The power industry is facing increasing

demands and operators are continuously

looking for solutions that help improve

safety and increase productivity. To do this,

operators need to select a lubricant that

can perform in a range of demanding

conditions including high temperature,

heavy load, and water contamination and

delivers outstanding product performance. A

technically advanced lubricant that can help

owners meet these goals will help keep plants

operating on top form.

Project Update

GE to deliver 2.6 GW of gas-fred power to EgyptGE has signed a contract with Egypts

government to deliver 2.6 GW of power

generation capacity.

GE Power & Waters Distributed Power

business said it will deliver 34 of its aeroderivative

gas turbines, which are expected to begin

generating power in May, as well as 12 heavy-

duty gas turbines to 15 sites across Egypt. The

frm said the contract was signed in December

2014 and construction is currently underway.

In the projects initial phase, fast-track power

solutions including 14 LM6000 turbines and 20

mobile TM2500 turbines will be delivered to

help offset Egypts expected summer power

demand, and some of the countrys existing

power plants will be upgraded with new

turbines. The second phase includes plans

for two full-scale power plants, which are

expected to generate 1495 MW.

According to GE, all of the promised

LM6000 turbines have already been delivered

and 10 have been installed, although they are

not yet up and running. The majority of the

trailer-mounted TM2500 turbines have been

delivered and are currently being installed.

The project is the largest to date for GE

Distributed Power. Given the speed required,

you can imagine that moving this amount of

equipment at this speed is quite a challenge,

Darryl Wilson, chief commercial offcer, told PEi.

You have the normal logistical challenges

involved with moving large equipment; road

infrastucture is important, and we have to

co-ordinate with the government on moving

equipment into rural places.

In addition, he noted that you have to have

the right competencies at these locations.

You have to get mechanical, electrical and

power plant engineers to multiple sites, not just

one site. Then there is clearing the sites, and

getting materials in and out.

Fuel fexibility is key to the project given the

number of remote locations, GE said, with the

turbines able to run on diesel as well as gas. In

these cases there is gas available to support

the equipment, Wilson said, and where

gas isnt available the diesel infrastructure

supports. For the future, he said that as the

gas and fuel infrastructure of the country

migrates, we can migrate with it.

We are very confdent that, by the

end of May, the government of Egypt will

have a very good outcome, Wilson said,

adding that GE had received extraordinary

co-ordination and support from the

government, including on transport, visas

for staff and moving equipment through

Customs.
