Abstract

Operating results are presented for an air-blown, fixed-bed coal gasification system, operating in conjunction with a low-temperature acid-gas removal system and integrated with a full-flow pressurized gas combustion apparatus. This pilot-scale system simulated the major subsystems of an integrated gasification combined-cycle (IGCC) power plant. The overall plant emissions goals of >90% hydrogen sulfide removal were achieved, and gas particulate loadings of <4 ppm, with a gas alkali metal content of <20 ppb, were measured. Gas turbine combustion emissions of carbon monoxide and oxides of nitrogen are reported as functions of the combustor exit gas temperature.
