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.

Abstract: A pressurized cyclonic combustion method and a cylindrical burner apparatus for pressurized combustion of particulate solid fuels to produce a pressurized clean effluent gas. In the burner, the particulate solids such as wood chips are fed tangentially into a primary combustion chamber at its inlet end and flow at high tangential velocity in a helical path through the burner. Oxygen-containing combustion gas such as air is supplied tangentially at high velocity through multiple ports spaced along the burner length to maintain and/or increase the high tangential velocity and produce high centrifugal forces on the particulate solids and provide for prolonged combustion and produce high burner volumetric heat release rates exceeding about 400,000 Btu/hr ft.sup.3. A choke opening is provided centrally located at the combustion chamber outlet end for promoting prolonged combustion of solid fuel paarticles upstream of a quench zone. A secondary combustion chamber is provided downstream of the choke opening.
