COMBUSTION DEVICE OF GAS TURBINE PLANT AND METHOD OF ITS OPERATION Russian patent published in 2021 - IPC F23R3/36 F02C7/22 

FIELD: gas turbines.

SUBSTANCE: according to the invention, the hydrogen-containing fuel can be stably ignited using a gaseous fuel that does not contain hydrogen, and the dispersion of the hydrogen-containing fuel can be increased. The combustion device of the gas turbine plant includes a burner including: a starting fuel pipeline in which the starting fuel circulates; a first main fuel pipeline in which the main fuel circulates; a second main fuel pipe in which the main fuel circulates; a fuel mixer to which a starting fuel line and a first main fuel line are connected; an internal fuel injector to which the fuel mixer is connected; a plurality of external fuel injectors to which the second main fuel line is connected; a starting fuel control valve provided in the starting fuel line; a first fuel control valve provided in the first main fuel line; and a second fuel control valve provided in the second main fuel line.

EFFECT: fuel dispersion increased.
