Heat for the power cycle of Units Nos. 1 & 2 of CESC, Budge Budge Generating Station is

derived from burning pulverized coal in a Natural circulation, balanced draft, two pass down–

shot fired, single reheat, single horizontal drum type boiler. Each unit has a single 250 MW

Parsons turbine generator, ABL boiler with a maximum continuous rating of 805 T/ hr.,

stream, and all auxiliary systems and equipment to make a complete generating unit.

Each boiler has been provided with two forced draft fans, three induced draft fans, two

primary air fans, one primary tubular air heater, two secondary tubular air heaters, six Ball

Race type pulverizes, six coal feeders, etc. Soot blowing is done. Light up is by EA ignition.

Main and reheat steam temperature is maintained from full load to 60 % load. The boiler is

capable of running without oil support for flame stabilization. 25 % BMCR requirement can be

achieved by burning HFO/ LSHS alone.

Feed water is taken from the de aerated feed water storage tank by motor driven feed water

pumps, and discharged through two stages of high pressure regenerative feed water heating

and flue gas economizer feed water heater into the boiler drum. Boiler water is in natural

circulation from the boiler drum through the furnace water walls back to the drum.

Separations of steam and water are accomplished in the drum and the steam is conveyed

through superheater sections of the boiler and intermediate two stages of desuperheating

stations. The steam cycle involved is a regenerative & reheating cycle with 3 cylinders of the

turbine HP (High Pressure), IP (Intermediate Pressure), LP (Low Pressure) cylinders.

Thereafter, the steam is expanded through the High-pressure cylinder of a tandem compound

turbine generator. After expanding through the high pressure turbine the steam is led back to

the reheater and reheat attempertor sections of the boiler, before being expanded through an

intermediate pressure turbine and low pressure turbine exhaust steam entering the

condenser. The condensate from condenser hotwell is again transported to the de aerator by

motor driven condensate extraction pumps through four stages of low-pressure regenerative

feed water heating system.

The turbine is capable of operation VWO normal pressure with all extractions in operation. It

utilizes electro-hydraulic controls. The start-up, shutdown and loading of turbine can be

achieved automatically. Turbine throttle pressure is 146 Kg/ Cm² (abs.) main steam

temperature is 537 ° C and reheat steam temperature is 535°C.

To facilitate cold start-up and quick reloading of the unit after temporary turbine outage, a 60

% capacity H.P. – L.P. turbine bypass system has been provided.

The turbine cycle includes two stages of feed water pumping (boiler feed pumps and

condensate extraction pumps), comprising seven stages of regenerative feed water heating



which it is based.

by turbine bled steam, viz., two high pressure regenerative feed water heating by turbine bled

steam, viz., two high pressure regenerative closed feed water heaters at the boiler feed

pumps discharge, four low pressure closed feed water heaters at the condensate extraction

pump discharge, and one direct contact heater (deaerator). All the feed water heaters are of

horizontal type. The two (2) lowest pressure heaters LPH – 1 & 2 are located in the neck of the

condenser and LPH – 1 is provided with an external drain cooler.

Each feed water heater drain is normally cascaded to the next lower pressure heater and the

lowest pressure heaters drains are cascaded to the condenser through condenser drains flash

box. Emergency drain of each feed water heater (except LPH – 4) is cascaded to the

condenser through condenser drains flash box. All heater drains are gravity type except LPH –

3 drains that is handled by a drain pump. Steam for regenerative feed water heating is

extracted from the turbine cycle at the exhaust from the high-pressure turbine (Cold reheat

steam), two intermediate stages of the intermediate pressure turbine, and one from the

exhaust of the intermediate pressure turbine, and three intermediate stages of the low-

pressure turbine.

Condensate is extracted from the condenser hot well pumped through the turbine gland

steam condenser, external drain cooler, four progressive stages of low pressure regenerative

feed water heating and sprayed into a direct contact deaerating heater. 2 x 100 % capacity

vertical condensate extraction pumps have been provided for this purpose.

Provision is kept for condensate bypassing of LP Heaters in two groups is the event of heater

flooding so that turbine is protected from water ingress, viz., LP Heaters – 2 & 1 and drain

cooler as one group, and LP Heaters – 3 & 4 as the other.

LP Heater – 2 drain is cascaded to LP Heaters – 1 via a flash box, while LP Heater – 1 drain is

cascaded to the condenser drains flash box via the drain cooler. LP Heater – 4 drain is

similarly cascaded to LP Heater – 3 while normal drain is pumped forward by a 1x 100% drain

pump via control valves to LP Heater- 3 main condensate outlet.

The turbine drives a 250 MW alternator with hydrogen cooled rotor and stator core, and DM

water-cooled stator windings at a speed of 3,000 rpm. The turbine shafts & generator rotor are

rigidly coupled together. The generator field is excited from a static system.

Deaeratad feed water from the deaertor feed water storage tank is pumped to the boiler flue

gas economizer by 2X 100% capacity boiler feed pumps through HP heater 6 & 7.Each boiler

feed pump consists of a booster pump and a main pump. Each HP heater can be by passed

individually from feed water side incase of heater flooding. HP Heater- 7 drain is cascaded to

HP Heater – 6, while HP Heater-6 is led to desecrator.



which it is based.

Initial air extraction from the condenser and steady vacuum inside the condenser is achieved

by motor driven, water sealed air extraction pumps. During normal operation of the plant

vacuum is maintained by one of the pumps.

Each unit is provided with a reserve feed water tank (RFW tank). It holds a supply of

demineralised water from condensate storage tanks through condensate transfer pumps.

RFW tanks provide the means of filling the deaerator and condenser and maintain the

condensate level within the condenser. It also supplies water to the condenser air extraction

system and condensate extraction pump seals. In addition, the RFW tank receives the surplus

condensate when there is excess in the system.

Two nos. separate condensate storage tanks, interconnected to each other, are provided for

both the units. Condensate storage tanks receive demineralised water from DM plant.

Condensate storage tanks provide water supply for boiler filling, RFW tank makeup, deaerator

filling, cooling water head tank make up, condenser emergency make up, stator cooling make

up and chemical feed system for both the units through set of pumps.

The flow to LP turbine low-pressure exhaust has been connected to single shell, horizontal,

two passes, divided water box, surface condenser. The split design of cooling waterside of

the condenser enables one half to be isolated for inspection while the other half remains in

service. The water boxes are lined with coal tar epoxy to counteract the corrosive qualities of

the cooling water. In addition sacrificial magnesium anodes, provided in each water box, give

back up corrosion protection by means of electrolytic reaction between dissimilar metals.

The condenser for each unit is supplied with circulating water from the cooling tower basin by

2X 50 % CW pumps which pumps water through the condenser and discharge it back to the

CT basin thus forming a closed cycle cooling. The CW supply headers of units 1 & 2 are cross-

connected.

The plant equipment cooling water system meets the requirement of the auxiliary coolers,

other than the main condenser. The whole, system is subdivided into two – system. The

primary circuit uses DM water and is of closed loop type. This is employed to pick up the

heat load from various auxiliary coolers under TG & boiler packages and to reject the same

to a set plate heat exchanger. The open loop secondary circuit water and is employed to

pick up the heat load from above plate heat.

Requirement of cooling water to TG oil coolers are met thru Aux. cooling water header for all

units.

The complete ash handling system is divided as bottom ash removal system and fly ash

Removal system. The fly Ash Removal system is continuous, whereas, bottom ash removal

system is intermittent and carried out once per shift.

Bottom Ash Removal system is a wet system. The bottom ash of each unit to crushed and

hydraulically conveyed in the form of slurry from bottom ash hopper to dewatering bins/ ash

tanks. Decanted water separated from the bins is further re circulated in the system. Trucks

remove collected bottom ash at the bins.

Fly ash collected in ESP & Air heater hoppers is removed in dry form by dense phase pneumatic

conveying system in tow stages. In the fist stage, fly ash collected in above hoppers is

pneumatically conveyed with compressed conveying air to Intermediate Surge Hoppers. In the

second stage, the dry fly ash is further conveyed with compressed conveying air to Intermediate

Surge Hoppers. In the second, the dry fly ash is further conveyed from Intermediate Surge

Hoppers to Fly Ash Silos by P-D pumps. Ash collected in fly Ash Silos is removed by trucks

through rotary un loader. Provision has been made to unload the ash from Intermediate Surge

Hoppers to trucks through unloading system in case of emergency.

Section III : Risks Improvement /Loss Preventions Suggestions

Risk Improvement Monitoring

A report of this type necessarily concentrates on the weak points and adverse conditions that

constitute a loss potential. The contents of the report, hence, should not be viewed as

implied criticism, but rather as support for management of the risks. Certain potential hazards

and conditions were evaluated during the plant round and were discussed with the fire/safety

department. The corrective actions are advised in order to eliminate or reduce the loss

potential. Completion of the following items will help to lower both the frequency and severity

of losses and minimize the possibility of costly business interruptions.

increase in temperature. At times there is every possibility of fire emanating from generator.

In order to quench such fire it is suggested to provide automatic CO2 flooding system and the

CO2 manifolds /cylinders should be kept outside the main power house.

02.12.27 Installation of inergen clean system for main power house control room

Category : Hardware condition, Priority medium

Inergen Systems for control rooms: Considering the criticality of process and importance

process control rooms, if logistics permits management might consider installation of inergen

system, which is one of the latest inventions in fire protection systems (used in Refinery and

Petrochemical plants). Some write-up on this system given here (taken from website) -

Inergen is an environmentally green three dimensional fire suppression agent replacing Halon

1301. Critical facilities such as data processing rooms, telecommunications switching

facilities, process control rooms, and others, require a non-water based extinguishing agent

that:

Is electrically nonconductive

Is safe for use in human occupied facilities

Would not damage sensitive electronic equipment



which it is based.


34


Has zero ozone depletion, zero global warming, and zero atmospheric lifetime

Inergen is a blend of three naturally occurring gases--Nitrogen, Argon, and Carbon Dioxide. It

is stored in cylinders near the facility under protection. The strategy of fire extinguishments

employed by an Inergen system is like no other modern suppression system in use today. An

Inergen system lowers the oxygen content of the protected area to a point sufficient to sustain

human life, but insufficient to support combustion. It's that simple. Because it's not a chemical

agent, Inergen will not produce a heavy fog the way other extinguishing agents do, so escape

routes remain visible. The Inergen discharges through specially designed nozzles. To

minimize turbulence in the protected area Inergen nozzles are fitted with discharge deflectors.

02.12.28 Oil leakage Lube oil pump area

Suggestions on Boiler

Have a competent service firm disassemble the low water cut-off and make-up water feeding

devices. All parts should be thoroughly cleaned and reconditioned as required, then tested

before the boiler is put into regular service. While in service the cut-off should be tested once

a week.

• Burner equipment should be cleaned and adjusted to give maximum efficiency. This can

save fuel costs.

• The boiler heating surfaces, firebox, ash pit, casing and ducts should be cleaned of all

deposits. Dirty internal surfaces not only waste fuel and additional costs , but also can lead to

the burning, bulging, cracking, corrosion and even explosion of the boiler.

• The safety/relief valve should be tested for freedom of operation. This is of primary

importance. The boiler must not be fired if the safety/relief valves are inoperative or otherwise

defective. These valves should be tested once a month while in service.

• If the boiler is of a type designed to permit cleaning of the water spaces, this should be

done, and, where necessary, a suitable chemical treatment should be used to minimize new

build-up of scale and to pre-vent corrosion.

• All pressure and temperature controls and gauges should be checked for satisfactory

operation and adjusted or replaced as necessary.

• The water level gauge glass must be cleaned to indicate the proper water level at all

times.Any leaking pipes or fittings located on the boiler or anywhere throughout the heating

system should be repaired or replaced to prevent a loss of water.

• All mechanical equipment, such as fans and pumps, should be checked for smooth

operation and proper lubrication.

• A suitable record of boiler operation should be established and maintained throughout the

year.

Suggestion for coal in open

Coal dumped at the coal yard is prone to spontaneous combustion; we suggest the following

precautionary measures -

Pile should be leveled by scraping and compacted by rolling. Distributing the coal

evenly avoids breakage and segregation of fine coal. The firm packing helps to shed

water

The sides of the pile should have a gentle slope as space limitations permit and

thoroughly compacted.



which it is based.


42


Clear site of all vegetation such as grass weeds etc.

Provide drainage to prevent accumulation of water.

Majority of hotspots will be within 1-1.25meters of the surface and all stacks should be

inspected weekly for overheating. Overheating could be detected by following

Smell – low volatile chemicals coming off

Discoloration – White/yellowish powder deposits

Vapour being given off- inside temperature will be in the region of 1200C.

Provision for water spraying system should be made all along the coal storage

facility,as the system is already there it is necessary to check whether entire storage

area is covered or not.

General recommendations

1. Consider sealing of the cable entries, ducts, pipes etc trench to wall etc using fire

stop sealants /concrete from wall to wall, wall to floor and cable passage

between two sections are properly sealed to prevent spread of fire or

percolation of rain/ storm /fire fighting water

2. Consider doing Thermography of cable joints and cables using infrared gun and

cable temperature are measured once in a year & records maintained

3. For the earthing resistance checks, it is suggested to display earth pit numbers on

the pit and record the date, reading and next due date of inspection on the earth pit

it self. All these suggestions from d to g apply to refinery area also.

4. Provide fire door to isolate boiler and turbine hall, however the same is kept in

open. Consider installation of a heavy door closure system so that the door is

normally in closed conditions.

5. It is recommended to have flameproof lighting at the battery room and all switches to

be changed to industrial type

6. For easy accountability of FEA (Fire Extinguishers Appliances), it is recommended to

form a codification/numbering system for the FEA and display those tags adjacent to

the FEAs. Also it is advisable that all FEA are mounted on wall or stand and not on the

floor, to avoid any accidental damage. Also identify the area below by yellow and red

lines for quick identification/accessibility during emergency. At some locations the

extinguishers are not easily approachable. It is recommended to keep the approach to

these extinguishers unhindered.

7. An Emergency action plan directing the workers to take the necessary action in case of

emergency should be prepare and displayed throughout the plant. This will enable the

workers to follow the instruction properly in case of any Emergency

5-7.4.2.1* Turbine generator bearings should be protected with a closed-head sprinkler

utilizing directional nozzles. Automatic actuation is more reliable than manual

action. Fire protection systems for turbine-generator bearings should be

designed for a density of 0.25 gpm/ft2 (10.2 mm/min) over the protected area.

5-7.4.2.2 Accidental water discharge on bearing points and hot turbine parts should be

considered. If necessary, these areas may be permitted to be protected by

shields and encasing insulation with metal covers.

5-7.4.2.3 If a manually operated water system is installed, consideration should be given

to a supplemental automatic gaseous fire extinguishing system.

5-7.4.2.4 If turbine-generator bearings are protected with a manually operated sprinkler

system, the following should be provided:

(a) Manual activation should be from the control room or a readily

accessible location not exposing the operator to the fire condition. Staffing of

plant should be sufficient to promptly handle this function as well as other

responsibilities during an emergency of this nature.

(b) Documented procedures should be in place with authorized approval

given to operators to activate the system if necessary in a fire condition.

(c) Periodic training should be given to operators regarding the need for

prompt operation of the system.

The risk engineer has attempted in identifying the hazards and bringing out loss prevention

best advices to mitigate them. The final conference was done with the plant management

team during which the risk improvement areas were discussed and the same has been

enumerated in this report.

A report of this type necessarily concentrates on the weak points and adverse conditions that

constitute a loss potential. The contents of the report, hence, should not be viewed as

implied criticism, but rather as support for the management. The corrective actions are

advised in order to eliminate or reduce the loss potential

In respect to the advice given in this report we would be glad to review your comments,

alternatives and action proposals or to provide further information if required. Implementation

of risk improvement suggestions will help to lower both the frequency and severity of losses

and minimize the possibility of costly business interruptions.

We would like to thank all those who contributed to this report, by helping during the survey,

providing information and co-operating in a very kind and open way. We certainly have

appreciated it and also the very kind hospitality throughout the visit.
