Abstract

In the coal gasification combined-cycle power generation system, it is necessary to develop a high-temperature gas turbine combustor using coal-derived gaseous fuels, which has high thermal efficiency and low emission of pollutants. Combustion tests were conducted using a full scale combustor for a 150-MW-class gas turbine under atmospheric pressure. Furthermore, high pressure combustion tests were conducted by using a 20-MW-class gas turbine combustor. Main results are as follows: Thermal NO_x emission was very low in a combustion of coal derived low Btu gaseous fuel, and its emission level was 15 ppm under a full load condition at of the combustor exit gas temperature of 1 300°C. The tested combustors were not designed for low fuel NO_x combustion. Therefore NO_x emission resulting from 1 000 ppmv of ammonia accounted for about 95 % of the total NO_x emissions, The ammonia conversion to NO_x decreased slightly with increasing of combustion pressure.
