Doosan Gas Turbine
It is well known that the Gas Turbine has played a leading role in power generation
arising from its high performance, reliability, fuel flexibility, low emissions and its
compactness etc.
Furthermore the Gas Turbine stands in a highlighted state of the art technology
with high efficient continuous operation (covering base load operation) as well as
peak load operation.
Doosan is capable of producing the heavy duty Gas Turbine models of M501G,
M501F, M701F and M701 under Technology License Agreement with Mitsubishi
Heavy Industries.Ltd.
Doosan has executed Yeongwol Combined Cycle Power Plant in South Korea by
applying M501F Gas Turbine. And also Doosan has manufactured full assembled
M501G Gas Turbine by Long Term Sourcing Agreement with MHI in Doosan
Changwon Plant.

Casings
All engine casings are horizontally split to facilitate maintenance with the rotor in place. Individual inner casings (blade
rings) are used for each turbine stationary stage and can be readily replaced or serviced with the rotor in place. Similar
blade rings have been added in the compressor seventh stage through last stage.
The aft-end bearing housing is supported by six tangential struts. Airfoil support the inner and outer-diffuser cones.
Tangential struts maintain alignment of the bearing housing by rotating it as required to accommodate thermal expansion.
Rotor Assembly
Similar to all past 501/701 series designs, the single rotor is made up of the compressor and turbine components. The
M501/M701 rotor is a bolted construction supported by two tilting-pad bearings. The thrust bearing is a tilting pad type.
The compressor rotor is comprised of a number of elements that are spigotted and bolted together by twelve through bolts.

Turbine
The turbine design of the M501/M701 maintains moderate aero-dynamic loadings in spite of the increased inlet
temperature by choosing a 4-stage turbine. Furthermore, improvements in aero-dynamic airfoil shapes have been made
possible by utilization of a fully three dimensional flow analysis computer code. The first and second stages on the turbine
rotor are the free-standing type. The third and fourth stages use integral shrouds.
Each row of vane segments is supported in a separate blade ring, which is keyed and supported to permit radial and axial
thermal response independent of possible external cylinder distortions.
Compressor
The compressor blade path is designed using a three-dimensional flow-field analysis computer program. Rotor blades are
double circular arc designs in the first four stages. Stationary blading, fabricated into two 180。diaphragms per stage for
easy removal, maintains the highly efficient inner-shroud sealing system.
These seals are supported by machined seal rings, which can be removed to facilitate inspection and maintenance of
shrouds and seals.
Turbine Blade
5 axle High Speed Milling Machine
Turbine Vane
The cooling circuits for the turbine section connsist of a rotor cooling
circuit and four stationary cooling circuits. Rotor cooling air is provided
by compressor discharge air extracted from the combustor shell.
Direct compressor discharge air is used to cool the row 1 vane.
Compressor bleed air from HP, IP and LP stages are used to provide
cooling air to turbine blade ring cavities at stages 2, 3, and 4
respectively. This suppply of bleed air also cools the stage 2, 3, and 4
vane segments and ring segments and provides cooling air for the
turbine interstage disc cavities.

Combustion System
The M501/M701 combustion system consists of 16 and 20 can-annular combustors, respectively. The combustion system is
a dual-fuel (natural gas and No. 2 distillate oil) system, which has provisions for steam or water injection for emissions control
and power augmentation. A new premix lean-burn hybrid combustor is to be applied to meet the existing and new NOx
emission limitations around the world. The hybrid combustor features a two-stage burner assembly and a bypass valve which
directs a portion of the compressor delivery air directly into the transition piece to enhance flame stability during starting and
to maintain desired fuel/air ratio during loading. This unique valving system then is modulated to full closed at full load.

Control System
Operation of the M501/M701 gas turbine and its combined cycle plant is supported by Mitsubishi plant control system
“DIASYS Series”. DIASYS Netmation is the latest gas turbine control system, which is Mitsubishi Heavy Industries’ total
plant control system also. It is a product that unites state-of-the-art info-com technology, MHI’s rich experience as a plant
manufacturer, and control technology for maximum satisfaction of such customer demands as high reliability, economy,
advanced automation, and easy maintenance.

■MULTIPLE PROCESS STATION(MPS) The Multiple Process Station used to perform
automatic turbine Control by I/O processing. It
features advanced arithmetic processing
capabilities that enable it to support a wide range
of applications that require high-speed processing,
such as turbine governor control as well as
automatic plant start/stop control.
■OPERATOR STATION(OPS) Operator station is a human-machine interface for
monitoring and operating a plant. Adoption of the
latest, most powerful, Windows XP based PCs
enables plant operator personnel to perform power
plant operations and monitoring with a minimal use
of time. Moreover, since screen configuration
elements have been implemented as components
based on Microsoft’s Active X component
technology, users can customize the OPS by
themselves.
■ENGINEERING MAINTENANCE STATION(EMS) Engineering Maintenance Station is an engineering
tool for performing maintenance of control system.
EMS provides the functions to perform a host of
operations, modification and creation of control
logic on Multiple Process Stations, design of
graphic displays, trends and control loop plates on
Operator Stations, and configuration of GT Control
systems. These operations are performed using
software named DIASYS-IDOL++. DIASYS-IDOL++
eliminates the need for burdensome programming
of a must of control and arithmetic processing.
