Abstract:
An apparatus for recovering heat and generating power from wastes, said apparatus c rising:a gasifier for gasifying wastes at a low temperature and thereby produce combustible gas;a burner for burning the combustible gas at high temperature to produce combustion gas containing at least one of alkali metal chlorides, calcium chloride, copper oxide and copper chloride;a waste heat boiler for cooling the combustion gas and for producing steam;a dust filter for filtering the thus cooled combustion gas at a temperature of from 450-650.degree. C. to thereby remove therefrom the alkali metal chlorides, calcium chloride, copper oxide and copper chloride as solid materials;a furnace for reburning the thus filtered combustion gas with auxiliary fuel to thereby reheat the combustion gas to a temperature sufficient to permit heat recovery therefrom;a steam superheater to receive the thus reheated combustion gas and the steam and to superheat the steam by recovery of heat from the combustion gas; anda steam turbine to receive the thus superheated steam and thereby to generate power.
