POWER PLANT Russian patent published in 2015 - IPC F02C6/00 

FIELD: power industry.

SUBSTANCE: invention relates to power industry and can be used for generation of electric energy at fuel utilisation by its combustion in flames, namely to low-duty power plants. A power plant includes a housing in the form of a stack, which is energetically isolated from environment, a bladed machine, with a possibility of operation in a compressor mode, a turbine drive, an electric generator in the form of a payload unit, a combustion chamber, atmospheric air supply elements, fuel supply elements, for example associated petroleum gas, and a high-temperature recuperative heat exchanger. A low-temperature recuperative heat exchanger is introduced to the power plant, and it is provided as an additional drive with at least one pneumatic motor, the inlet of which is interconnected with the compressor outlet, and the outlet of the pneumatic motor is interconnected through the combustion chamber and the stack cavity with atmosphere. The low-temperature recuperative heat exchanger is located in the stack cavity after the high-temperature recuperative heat exchanger. Each pneumatic motor is connected to one electric generator being its only drive.

EFFECT: invention is aimed at improvement of efficiency of a power plant, increase of thermal efficiency, simplification of the design as a whole and enlargement of a range of stable operation.
