THE TECHNICAL EVALUATION OF CURRENT HTHP GAS PARTICULATE COLLECTORS FOR INTERGRATED COAL GASIFICATION COMBINED CYCLE

摘要

The particulate collector is important to prevent the gas turbine from erosion and to meet the emission limits of the effluent gas in the advanced coal power system. The specifications for particulate collection in Integrated Coal Gasification Combined Cycle (IGCC) require nearly absolute collection efficiency and system reliability. Collection processes being currently developed; advanced cyclone, cross flow filter, granular bed filter, electrostatic precipitator, and candle filter were evaluated in order to select the optimum system for IGCC. Among them, ceramic candle filter has the best potential for IGCC at this moment.
