Abstract
A pressurized incineration method for pressurized incineration of a solid waste material to produce electrical and thermal energy is disclosed. A combustion chamber is fueled by a solid waste fuel. The chamber is pressurized by an air compressor and the fuel is combusted. The hot compressed gases created by combustion pass out of the combustion chamber into an exhaust line that splits so as to provide hot gases to a turbocharger and a separate power recovery turbine. The turbocharger and the power recovery turbine have a rugged design so as to handle compressed gases containing corrosive effluents and particulate matter. If necessary, gas cleaning equipment may also be used to reduce corrosive effluents and particulate matter to an acceptable level in the inlet gas stream to both the turbocharger and the power recovery turbine. Expansion of a portion of the hot compressed gas through the turbine section of the turbocharger provides energy to drive the turbocharger's air compressor. Expansion of the remaining hot compressed gas through a separate power recovery turbine creates mechanical energy that may be converted to electricity by an electrical generator.
