ABSTRACT:
An integrated coal gasification combined cycle (IGCC) plant which appropriately processes an early produced gas to suppress the emission of a sulfur component into the atmosphere for further improving environmental compatibility is provided. The IGCC plant has a gasifier for converting pulverized coal to gas fuel, a gas turbine operated thereby and supplying a combustion exhaust gas to an heat recovery steam generator, a steam turbine operated by steam generated thereby, and a power generator connected to the gas turbine system and/or the steam turbine. In this IGCC plant, a combustion exhaust gas discharged from the heat recovery steam generator is desulfurized and exhausted into the atmosphere. In addition, an initial desulfurization equipment exclusively used for the early produced gas is provided for a flow path extending from an outlet side of the gasifier to a flare system.
