1. The following are the details of performance improvement.
A. As for the background information,
○ SeoIncheon Combined Power Plant has been confronted with the necessity to reduce greenhouse gas emissions through efficiency improvement, carbon dioxide reduction and NOx emission reduction.
– At the time of the review in 2001, the regulated amount of emission allowed was 100ppm and the plant’s emission was measured at 60ppm.
– Nevertheless, there has been a strong will to reduce the emissions to below 15ppm through the utilization of the latest equipments.
B. And now is the progress of the project.
○ A two-year review and cooperative agreement with the related departments have been completed on May 20, 2003.
○ The plan was first applied to the Machine #1 on December 4, 2003 and the trial was completed in 40 days of the OH period and the application to the all machines was completed in 2006. Page 4
C. The following improvements have been made to facilities.
○ The gas turbines were upgraded from DLN1.0 to DLN2.6 and gas turbines and compression rotors at 9 locations were replaced as well.
○ The control system was upgraded from Mark IV to Mark VI.
○ Also, improvements were made to some parts of the turbine auxiliary systems. Especially, we have accomplished energy reduction through the efficient use of emission gas by lowering the temperature of the emitted gas from 125℃ to 110℃, which has been lowered by preventing heat loss from the passing and leaking of the emission gas.

D. Major improvements to gas turbine were as follow:
○ Gas turbine replacement, turbine performance improvement, compressor structure reformation, thrust bearing installation, and marriage flange modification |
