Claims
- 1. A combined power generating plant, comprising:
- a coal gasifying furnace;
- gas cooler means for recovering sensible heat of gas produced in the coal gasifying furnace by generating steam with the heat so recovered;
- gas purification means for removing impurities contained in the so cooled gas;
- a gas-turbine electric power generating unit having a burner for burning the gas purified in the gas purification means;
- waste heat boiler means for generating steam by recovering the sensible heat contained in exhaust gas from said gas-turbine electric power generating unit;
- a steam-turbine electric power generating unit fed by the steam from said gas cooler and from said waste heat boiler; and
- a catalyst burning system disposed between said gas purification means and said waste heat boiler means parallel to said burner of the gas-turbine electric power generating unit so as to burn combustible waste gases produced in the gasifying furnace during the start-up operation of the plant and so that catalytically burned exhaust gas is supplied to said waste heat boiler means.
- 2. A combined power generating plant as claimed in claim 1, and further comprising valves connected to exhaust gas outlets of the coal gasification furnace, the gas cooler and the gas purification unit so as to cause exhaust gas to flow to said catalyst burning system disposed parallel to said burner of the gas-turbine electric power generating unit.
