Abstract:
A method of recovering heat and generating power from wastes, said method comprising:burning said wastes to thereby produce combustion gas containing at least one of alkali metal chlorides, calcium chloride, copper oxide and copper chloride;cooling said combustion gas in a waste heat boiler to produce steam;subjecting the thus cooled combustion gas to dust filtration at a temperature of from 450-650.degree. C. to thereby remove any said alkali metal chlorides, said calcium chloride, said copper oxide and said copper chloride as solidified materials, and thereby producing cooled and filtered combustion gas;reburning said cooled and filtered combustion gas with auxiliary fuel to thereby reheat the combustion gas to a temperature sufficient to permit heat recovery therefrom;introducing the thus reheated combustion gas into a steam superheater, and passing said steam through said steam superheater, thereby recovering heat from said combustion gas and superheating said steam; andintroducing the thus superheated steam into a steam turbine and therein generating power.
