  • Control system for IGCC's
    Patent number: 5688296
    Abstract: A control system particularly suited for effecting control over an integrated gasification combined cycle system (IGCC) that includes at least a fuel feed system, a gasifier system, a product gas cleanup system, a booster compressor and a gas turbine. The subject control system includes a bleed air control valve, a booster compressor bypass control valve, a fuel feed control valve and a product gas shutoff valve. The bleed air control valve, which is connected in fluid flow relation between the gas turbine and the booster compressor of the IGCC, is operable for effecting control over the amount of air that is bled in the IGCC. The booster compressor bypass control valve, which is connected in fluid flow relation between the upstream side and the downstream side of the IGCC, is operable for effecting the bypass of air around the booster compressor of the IGCC.
