Study through questionaire (6) Cherepetskaya (7) Ulan-ude (8) Verkhnetagilska (9) Bogoslovskaya


[3]Efficiency Improvement Measures

Replace - Replace-1; Replace coal-fired plants to GTCC plants.

- Replace-2; Replace units to USC-PCF. Convert -Convert ;Convert the boilers to use natural gas. Evaluation of cost effectiveness was done by 30yeras on replace and

15years on covert.

[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 (300MW× ４； Shandong province) Louhe(300MW×2 ； Anhui province) Yaomeng (300MW×2 ； Henan province)1)Poor boiler efficiency and boiler outlet gas’s 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.


Boiler facilities

-Modification; water walls,combustion equip’,air heater

-Use of; gas re-circulation system,soot blower

-Increase the area of ECO and decrease the area of RH.

Turbine facilities

-Replacement; HP turbines,IP turbines,bearings,coupling bolts and nuts

-Improving; vacuum condition in the condensers

[3] Efficiency Improvement Measures.


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.


184,000t-co2/y at 2010(improve 4% thermal efficiency of plants)

(=co2 emission from one 300MW unit for a whole year)

CO2 Emission Reduction Effect(2)


Technical Findings

Many promising projects for AIJAIJ,CDMCDM schemes in RussiaRussia and ChinaChina.

Thermal Efficiency upgrading achieve not only CO2 reduction but also produce another benefit (reduction of other pollutants and fuel

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

is needed.


Findings in Financing-1

Good financing schemes are necessary.

-Japanese official funding

ex,JBIC ; ODA, S/C,B/C,B/L,untied loan, OIC

-Private funding

ex,ROT, ROO

-International funding

ex,IBRD, IFC, EBRD


Findings in Financing-2

Risk hedging

High risk for commercial base.

Governmental guarantee for financing.

Low interest schemes for financing.
