A system may include a compressor, a heat exchanger and an ITM. The compressor is configured to receive an air stream and compress the air stream to generate a pressurized stream. The heat exchanger is configured to receive the pressured stream and indirectly heat the pressurized stream using heat from an oxygen stream from an Ion Transport Membrane (ITM). The ITM is configured to receive the heated pressurized stream and generate an oxygen stream and the non-permeate stream, wherein the non-permeate stream is passed to a gas turbine burner and the oxygen stream is passed to the heat exchanger.

The invention relates to a method for operation of a combined-cycle power plant with cogeneration, in which method combustion air is inducted in at least one gas turbine, is compressed and is supplied to at least one combustion chamber for combustion of a fuel, and the resultant exhaust gas is expanded in at least one turbine, producing work, and in which method the exhaust gas emerging from the at least one turbine is passed through a heat recovery steam generator in order to generate steam, which generator is part of a water-steam circuit with at least one steam turbine, a condenser, a feedwater tank and a feedwater pump, wherein heat is provided by extracting steam from the at least one steam turbine. In a method such as this, the electricity production is decoupled from the steam production in that in order to restrict the electricity production while the heat provided by means of steam extraction remains at a constant level, a portion of the inducted combustion air is passed through the at least one turbine to the heat recovery steam generator without being involved in the combustion of the fuel in the gas turbine, and in that this portion of the combustion air is used to operate at least one supplementary firing in the heat recovery steam generator.

A thermal motor system comprises a combustion chamber connected to an accumulating chamber of the fluid produced by combustion by a control valve. A fluid actuator is driven by an operating fluid coming from the accumulating chamber. The combustion chamber has a fixed volume and does not contain elements moved by the fluid produced by combustion.

A gas turbine engine (14) with a turbine (25) with an exhaust manifold (48) thereabout from which fluids can be transferred to the turbine and an air compressor (23) having an air transfer duct (30) extending therefrom so as to be capable to provide compressed air in that air transfer duct at one end thereof to the air intake (32) of an internal combustion engine (34) provided as an intermittent combustion engine. The air intake and an exhaust outlet (39) are each coupled to combustion chambers (35) therein and a rotatable output shaft (40) is also coupled to those combustion chambers for generating force. The exhaust outlet has an exhaust transfer duct (46) extending therefrom so as to have the intermittent combustion engine be capable to provide exhaust therefrom in that exhaust transfer duct at one end thereof, and the exhaust transfer duct being connected at an opposite end thereof to the exhaust manifold (48) to be capable of transferring intermittent combustion engine exhaust thereto. A method of generating force and electrical power uses such an engine combination.
摘要:
A gas turbine topping device, which is disposed upstream of a steam-raising section, is used for generating power in the manufacture of sulphuric acid. A sulfur-burning combustor generates hot sulfur dioxide while a pressure-exchanging ejector mixes the hot combustion gases with a cooler gas (e.g. pressurized air, pressurized N 2 or recycled sulfur dioxide (SO 2 ) to form a mixed working gas having a temperature below the maximum allowable temperature (metallurgical limit) of the blades of the turbine. The turbine drives an oxygen compressor which supplies oxygen to a bubbling chamber which also receives S 8 to produce sulfur vapor for combustion. By using stoichiometric quantities, sulfur dioxide is delivered in requisite quantities to a sulfuric acid plant without any harmful emissions. Useful amounts of electrical power can thus be generated by the gas turbine topping device as well as the downstream steam turbine by harnessing the enormous amount of waste heat involved in the manufacture of sulfuric acid.
