ENERGY PLANT WITH HIGH-TEMPERATURE STEAM-GAS CONDENSATE TURBINE Russian patent published in 2019 - IPC F01K25/00 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering. Power plant comprises main gas line of natural gas, air separation plant for oxygen production, electric driven compressors for pressure of oxygen and natural gas, steam-jet compressors, two adiabatic reactors for methane steam reforming, solid-fuel steam boiler, high-temperature steam superheater of high pressure, high-temperature condensing steam-gas turbine plant with condenser, vortex separator of steam and carbon dioxide, gas turbine. Oxygen produced in air separation plant is compressed in electrically driven compressor and supplied to high-temperature combustion chambers of high and medium pressure. Natural gas is compressed from main gas line in electric drive and steam-jet compressor and mixed with superheated steam generated by steam boiler. In the first adiabatic reactor at temperature of 500 °C methane-containing mixture of steam with hydrogen concentration of 5 % is obtained. Heating of this mixture, supplied to the second catalytic reactor, up to 620 °C is produced in the cooling jacket of the combustion chamber of a high-temperature high-pressure steam superheater. Use of two adiabatic conversion reactors in the installation makes it possible to supply a methane-hydrogen mixture with a hydrogen content above 20 % to the high-pressure combustion chamber.

EFFECT: invention allows to increase economy and to improve environmental friendliness of the power plant.
