[2] General Study of Existing 300MW

Coal-fired Power Plant Units. 100 300MW class coal-fired power plants.

(20% of coal-fired power plants.)

(1) 75% are made of China.

(2) Low thermal efficiency and fall short of

designed performance.

(3) Reliability of plant facilities are low.

[3] On Site Study of 3 PCF Power Plants.

Zhouxian (300MWShandong province)

Louhe(300MW2Anhui province)

Yaomeng (300MW2Henan province)1)Poor boiler efficiency and boiler outlet gass temp is high.

2)Plants stop frequently due to boiler tube leak at water wall.

3)Poor turbine efficiency and vacuum condition of condenser.

4)Turbine casings have caused thermal strain deformation.

5)Only within 100-80% lord change of boilers.

6)Manual operation of lord change,start-up and shut down.

CO2 Emission Reduction Effect(1)

Project plan was suggested.

Implementation of upgrading 10 300MW made-in-China

power units by the year 2010.

The CO2 reduction effect and cost-

effectiveness of the project has been

examined.

Technical Findings

Many promising projects for AIJ,CDM

schemes in Russiaand China.

Thermal Efficiency upgrading achieve notonly CO2 reduction but also produce

another benefit (reduction of other pollutants and fuel

consumption etc).To move next stage, further detailed study

is needed.
