摘要： A combined cycle waste-to-energy plant is utilized to thermally convert municipal and industrial solid wastes into essentially complete products of combustion and use the combustion heat to produce steam and/or electrical power. The plant includes a building enclosure having a waste receiving area, a waste fuel separation and processing area, an incinerator area and a heat recovery and power generation area. Processed waste fuel is delivered to a series of incinerators by an automated conveyor and hopper system, and the waste fuel is burned in the incinerators by hot exhaust gas delivered thereto from one or more combustion turbines located outside the building and drivingly connected to electrical generators. Inlet air to the turbines is drawn from with the building to maintain its interior at a negative pressure, thereby preventing waste odors and pathogens from escaping from the building. Hot combustion turbine exhaust gas delivered to the incinerators is passed through a superheater, and a portion of the exhaust gas exiting the superheater is passed through a waste heat recovery boiler. Hot combustion gas discharged from each of the incinerators is passed through an associated combusion heat recovery boiler. Gas heat recovered in the superheater and the various boilers is utilized to produce steam which operates a steam turbine drivingly connected to an electrical generator. A portion of the steam generated may also be used for process purposes.
