METHOD FOR OPERATION OF COMBUSTION DEVICE FOR GAS TURBINE AND COMBUSTION DEVICE FOR GAS TURBINE Russian patent published in 2019 - IPC F23R3/34 

FIELD: technological processes.

SUBSTANCE: operating method of a combustion device for a gas turbine, comprising at least a first combustion chamber, a deflecting assembly and a sequential combustion chamber. In the first combustion chamber, the pre-mixed fuel-air mixture is burnt in a stable flame at an average flame temperature of 1550 to 1800 K. On the downstream end of the first combustion chamber and upstream of the deflecting unit, the mass flow of the additional air is injected into the hot gas stream for In order to reduce temperature below 1400 K. Then mixture of hot gases and additional air is introduced into deflecting unit and deflected in it at least in circumferential direction. Mass flow of additional fuel is injected downstream of location of said air injection, forming a mixture of hot gases, air and fuel with self-ignition time from 1 ms to 10 ms. Mixture of hot gases, air and fuel is burnt in a sequential combustion chamber by means of self-ignition or a combination of self-ignition and recirculation of hot reaction products.

EFFECT: invention enables combustion of different types of fuel, low NO_x and CO emissions and high thermal efficiency.
