STEAM GENERATING PLANT Russian patent published in 2012 - IPC F02C3/34 

FIELD: machine building.

SUBSTANCE: steam generating plant includes pressure unit, burner device and steam generator. Pressure unit consists of gas turbine and air compensator connected to it via power train, for example, shaft. Compensator input is connected to atmosphere. Steam generator has channels of hot and cold heat-transfer mediums with inlets and outlets correspondingly. Burner device is equipped with inlet for air, fuel supply and hot gas outlet. The outlet of pressure unit compensator is connected to burner device inlet for air supply. The inlet of pressure unit gas turbine is connected to the outlet of burner device through hot heat-transfer medium channel of steam generator and turbine outlet - to the atmosphere. The inlet of cold heat-transfer medium channel of steam generator is connected to the source of heated medium, and the channel outlet - to the receiving device of heated medium. The plant additionally contains air booster compressor, ballast gas compressor, second gas turbine, everything with inlets and outlets correspondingly and useful load, for example, electric generator. Air booster compressor, ballast gas compressor, second gas turbine and electric generator are mounted on one shaft. The outlet of pressure unit air compressor is connected to the inlet of burner device through air booster compressor. The inlet of hot heat-transfer medium channel of steam generator is connected to the hot gas outlet of burner device through the second gas turbine. The outlet of hot heat-transfer medium channel of steam generator is additionally connected to the inlet of burner device through ballast gas compensator.

EFFECT: invention allows increasing coefficient of performance and operational life of the plant, reducing its size, material consumption and cost, reducing the number of nitrogen oxides generated during operation.
