COMBUSTION CHAMBER Russian patent published in 2024 - IPC F23R3/00 

FIELD: machine building.

SUBSTANCE: invention relates to turbine plants, particularly, to turbine combustion chamber. Combustion chamber of constant volume is equipped with compressed air supply system, fuel supply nozzle, fuel ignition device, check and shutoff valves having the possibility to occupy open and closed positions. Combustion chamber is equipped with a heat-insulating circular channel for heating compressed air, the temperature of which is determined by a sensor, and has heat-insulated inner walls forming a Laval nozzle in the upper part of the combustion chamber, fuel direct injection nozzle and fuel ignition means are installed at the inlet of the Laval nozzle. At the same time in the lower part of the combustion chamber the fuel-air mixture combustion sensor is installed, and the outlet channel having heat-insulated walls passes into the Laval nozzle.

EFFECT: obtaining high thermal efficiency of the turbine and minimizing harmful emissions of exhaust gases into the atmosphere due to complete fuel combustion in each cycle, which is ensured by maintaining a stable stoichiometric composition of the fuel-air mixture in the combustion chamber in the entire range of durations of operating cycles.
