goal of the peer review activities
Goal of the Peer Review Activities
  • The goal of the Peer Review Activities is to share the best practices of operation and maintenance of the coal-fired thermal power plants with approximately the same operational period, through the activities such as;
    • open and frank discussion among plant engineers with consecutive site visits
    • development of database of review items
    • development of a check-list for efficiency improvement
    • development of a handbook for lateral and wider dissemination of accumulated knowledge.

The 1st Peer Review Activity focusing on maintaining & improving thermal efficiency of aged Coal-fired Thermal Power Plants’

  • Period: April 16, 2007 ~ April 20, 2007
  • Place:J Power, Takasago Power Plant, etc.
  • Participants:37 people from China, India, USA, Republic of Korea, Australia
  • Activities:

 ・Exchange opinions in regards to the “Factors that causes thermal efficiency  

deterioration ”

  •  ・Peer review at Takasago Thermal Power Station, Japan
  •  ・Exhibition on the subject of “Environment,” “Thermal Efficiency Improvement”
  •  ・Site visit to Hitachi Naka Thermal Power Station, Japan
  •  ・Site visit to Harumi Island Triton Square (regional heat supply facility)

( Co-sponsored by Ministry of Economy, Trade and Industry and FEPC )

Results of the 1st peer review (1)

Opinions from the participants

  • We are impressed by the Japanese colleagues’ careful management of coal

fired power plants to  maintain high thermal efficiency over the long

period of time.

  • We are eager to learn about this style of careful operational management

technology developed  by Japanese colleagues.

  • We would like to bring the knowledge we obtained back and apply it to our

plants.

  • Activities such as the Peer Review should be consecutively conducted in all

APP participating  countries.

Results of the 1st peer review (2)

Fundamental Factors for efficiency improvement

  • Organizing and analyzing the historical maintenance information
  • Monitoring and analyzing the operating information
  • Integrating the above information and developing the O&M

program from the long term perspective

  • The significance of the Peer Review Activities has been shared among the participants.
  • Common recognition that appropriate day to day operational management is necessary to maintain thermal efficiency, was firmly produced.

Benefit of the appropriate day to day operational management

Energy & cost saving and air pollution reduction can be achieved by implementation and dissemination of the best practices in operation and maintenance shared through the Peer Review Activities.

In addition, the improvement in efficiency or the avoidance of potential degradation of thermal efficiency could further lead to the CO2 emissions reduction.

Official Tool for Implementation of Peer Review

( 2nd Peer Review in India)

  • “Green Handbook”, “Checklist”,”Review Sheet”,

and the “Procedure” were approved as official tool

at 2nd Peer Review in India

  • These tools were proposed and prepared by JAPAN
  • Application of them is already being by USA and

China

  • Available on the FEPC Website:

Japan’s Proposal of Operation and Facilities Improvements

( 2nd Peer Review in India)

  • At the 2nd Peer Review in India, Japan proposed

 an applicable methodology. The “Review Sheet”

 of the Kota Power station gives us an example of

 its application.

・Auxiliary power of major

 fans can be reduced by lowering

 the economizer outlet O2.

・Boiler efficiency can improve by

reducing the spray flow through

combustion optimization.

(Further investigation and follow-up activities

are expected for full implementation. )

Assumption

Load factor: 50%

Turbine efficiency: back to the design

RH spray flow: 0, SH spray flow: same as the heat balance diagram

AH air leakage: same level as Japan’s power plant

(Factors: SAH steam reduction, FDF power reduction, combustion air temperature)
