ENVIRONMENTALLY SAFE GAS-TURBINE PLANT OF REGENERATIVE CYCLE WITH CATALYTIC COMBUSTION CHAMBER, AND CONTROL METHOD OF ITS OPERATION Russian patent published in 2013 - IPC F02C3/14 F23R3/40 

FIELD: machine building.

SUBSTANCE: environmentally safe gas-turbine plant of regenerative cycle with a catalytic combustion chamber includes an axial compressor, a turbine, a recuperative heat exchanger, a catalytic combustion chamber connecting their gas-air channel, a fuel system with an atomiser, an automatic control system and load. The gas-turbine plant is also equipped with an air distributing mechanism, a device for change of torque moment on the shaft of load and a turning device of guide vanes of the axial compressor, which are connected to the automatic control system. The catalytic combustion chamber is made in the form of an in-series located vortex mixing chamber, an auxiliary chamber combined with it and a catalytic reactor. The recuperative heat exchanger is of a plate type and equipped with a plate temperature determining device arranged between them in hot part of the recuperative heat exchanger. The atomiser of the fuel system is arranged in the air-gas channel attaching the recuperative heat exchanger to the vortex mixing chamber. The air distributing mechanism is installed in the air-gas channel after the compressor. One of the outlets of the air distributing mechanism is gas-dynamically connected to the inlet of the recuperative heat exchanger, and the other outlet is connected to the inlet of the auxiliary combustion chamber.

EFFECT: improving operating efficiency and reliability of a gas-turbine plant with a catalytic combustion chamber; enlarging its functional capabilities; improving environmental cleanliness of combustion products.
