GAS TURBINE POWER PLANT HAVING RECYCLING OF EXHAUST GAS Russian patent published in 2017 - IPC F02C6/00 

FIELD: machine engineering.

SUBSTANCE: gas turbine power plant comprises a gas turbine device comprising a compressor, at least, one burner and, at least, one gas turbine, a heat recovery boiler unit having an inlet side of the boiler connected to the outlet of the turbine, the first boiler outlet connected to the exhaust pipe, the second boiler outlet and an exhaust gas recirculation that connects the second boiler outlet with the compressor inlet. The simplified design can be achieved in that the heat recovery boiler unit has the first exhaust gas path of the boiler, which is connected to the boiler inlet side and leads to the first boiler outlet and in that the heat recovery boiler unit has the second exhaust gas path of the boiler that is connected to the boiler inlet side and leads to the second boiler outlet separate from the first exhaust path of the boiler.

EFFECT: invention allows to increase the efficiency of the power plant and to reduce emissions of pollutants.
