Abstract
The economics of waste disposal are markedly improved by combining a waste-burning plant with a gas turbine-generator set, with exhaust gas from the gas turbine fed as combustion air into a waste-burning incinerator. A boiler associated with the waste-burning incinerator supplies steam to operate a steam turbine and a second electric generator.
Claims12
A waste-burning plant, comprising, in combination:
- a gas turbine generation means which includes a gas turbine and a first electric generator mechanically connected to be driven by said gas turbine;
- a waste-burning incinerator;
- a boiler, said incinerator being connected to receive at least a portion of the exhaust from said gas turbine as combustion air, to receive a waste, to burn said waste and to supply heat to said boiler to generate steam;
- a steam turbine and a second electric generator, said steam turbine being connected to receive steam from said boiler and connected to drive said second electric generator.
In a combined cycle power generation system having an externally-fueled gas turbine driving a first electrical generator, a boiler receiving exhaust from said gas turbine and producing steam, a steam turbine driven by said steam and a second electrical generator driven by said steam turbine, the improvement which comprises:
- a waste-burning incinerator connected to receive at least a portion of the exhaust gas from said gas turbine as combustion air and to receive a waste fuel, and connected to supply heat to said boiler.
The method of disposing of municipal solid wastes comprising the steps of:
- feeding said wastes to a waste-burning incinerator, generating steam by combusting said wastes in said incinerator, generating electric power by supplying said steam to a steam turbine-generator set and supplying hot exhaust gas from a gas turbine-generator set to provide combustion air to said incinerator.
