Integrated Coal Gasification Combined Cycle Power Generation (IGCC) is one of the most promising advanced power generation systems with its superior environmental acceptability and high thermal efficiency.
Cool Water Coal Gasification Program (CWCGP) is a project in which IGCC plant incorporating an entrained flow type Texaco gasifier is being demonstrated. Besides the participants in the United States such as Texaco, Southern California Edison and EPRI, a Japanese consortium (JCWP) led by Tokyo Electric Power is participating in CWCGP.
Construction of CWCGP plant was initiated in December 1981 and was completed in April 1984. Total construction capital was 263 million dollars, approximately 10% lower than the original budget.
After the commissioning operation and 10 days acceptance test, demonstration phase of CWCGP was started in June 1984.
Since then the plant has been operated successfully and the cumulative operation and the capacity factor at the end of September 1985 reached approximately 6000 hours and 44% respectively. And the run length record during this period was 640 hours.
Encouraged by the success of CWCGP, a plan of constructing a commercial IGCC plant in 1990's was announced in the United States this spring.
