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 180diaphragms per stage foreasy 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.

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, MHIs 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 Microsofts 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.
