MODE OF GAS TURBINE PLANT OPERATION ON METHANE-CONTAINED STEAM-GAS MIXTURE AND ITS ACTUALIZATION DEVICE Russian patent published in 2017 - IPC F02C3/28 

FIELD: electricity-producing industry.

SUBSTANCE: mode comprises the generated superheated high-pressure water steam injection into the combustion chamber, the steam most part injection into the combustion chamber, the superheated steam smaller part mixing with the natural gas, the injection and obtaining the methane-contained steam-gas mixture in the first adiabatic catalytic reactor, this mixture series heating-up by the gas turbine exhaust gas heat energy, and then by the heat energy of the combustion chamber cooling up to the 620-680°C temperature, the hydrogen density strengthening in the methane-contained steam-gas mixture above 20% in the second adiabatic catalytic reactor and this mixture injection in the function of the propellant into the gas turbine plant combustion chamber. The mode is implemented into the device, which comprises the compressor, the combustion chamber with the cooling jacket, the gas turbine, the conduit of the superheated steam injection into the combustion chamber, the driving assembly, the recovery boiler, which comprises the evaporator plant, the superheater, the convective heater of the methane-contained steam-gas mixture, the combustion products cooling and low-pressure steam condensation system, the natural gas pipeline, the steam conduit of the high-pressure steam, the mixer, two adiabatic catalytic reactors.

EFFECT: thermodynamic and economical effectiveness upgrading of the plant, its design simplification and reliability growth.
