ABSTRACT:
The gasification-combined power plant of the present invention has a structure wherein a fuel gas is generated by partially oxidizing a carbon-containing fuel 2 with an oxygen-containing gas 3 in the gasification apparatus 1, the sensible heat of the fuel gas is recovered by the heat exchanger 4, char and dust are removed from the fuel gas by the dust collector 5, trace gas components, such as H.sub.2 S and NH.sub.3, are simultaneously removed from the waste gas by the gas separation apparatus 6 based on dry physical adsorption of these components (for example, by a pressure swing adsorption method), the thus separated and removed gas containing high concentrations of trace gas components, such as H.sub.2 S and NH.sub.3, is denitrated and desulfurized by the gas disposal apparatus 7 and then is discharged from the chimney 13 into the atmosphere. With the simultaneous removal of the trace gas components at a high temperature from the fuel gas produced by the gasification apparatus, this plant simultaneously achieves both a high heat efficiency for the gasification-combined power plant as a whole and the reduction of sulfur oxides and nitrogen oxides in the combustion waste gas from the gas turbine.
