TURBOMACHINE COMBUSTION CHAMBER Russian patent published in 2003 - IPC

FIELD: gas-turbine engines; ground-based gas-burning turbomachines exhausting low-toxicity gases. SUBSTANCE: combustion chamber has a number of gas fuel flow governors and fuel-air mixture flow governors, as well as driving mechanisms of each of gas fuel flow governors and of each of fuel-air mixture flow governors, each incorporating air flow governor. Each of fuel-air mixture flow governors is made in the form of tangential swirler burner and central body for its displacement along burner axis. Driving mechanism of each gas fuel flow governor is made in the form of revolving shaft provided with eccentric cam of central body, gas and air throttle valves, crank lever and its turning device. Central body is provided with perforated screen and also with central bore affording communication between combustion chamber interior and burner inner space. Revolving shaft levers are joined with crank-lever turning device by means of synchronizing ring disposed around external casing. Channel-carrying surface of screen and its surface inside burner are made in the form of body of revolution about central body axis. EFFECT: reduced toxicity of combustion products; enhanced fuel saving efficiency of combustion chamber. 6 cl, 5 dwg
