STEAM AND GAS TURBINE PLANT Russian patent published in 2014 - IPC F01K21/04 F01K23/10 

FIELD: machine building.

SUBSTANCE: steam and gas turbine plant consists of an inlet unit, a compressor, a combustion chamber, a mixing chamber, a compressor drive turbine, an outlet unit, an evaporating heat exchanger, a heating heat exchanger set after the evaporating heat exchanger, a steam turbine, a condensing heat exchanger. The evaporating heat exchanger is installed in the channel of the outlet unit after the compressor drive turbine and is connected to a water source on one side and to the mixing chamber on the other side. Prior to getting to the evaporating heat exchanger, water passes through the condensing heat exchanger of the steam turbine. The steam turbine circuit is closed: the inlet receiver of the turbine is connected to the outlet of the heating heat exchanger, the outlet receiver of the turbine through a low pressure channel of the condensing heat exchanger is connected to the inlet of a pump with the outlet of the latter being connected to the inlet of the heating heat exchanger. A high volatile liquid transforming into steam and back (for example, ethyl alcohol) with a boiling temperature below 100° is circulating in the steam turbine circuit.

EFFECT: increased efficiency of a steam and gas turbine plant.
