FIELD: machine building.SUBSTANCE: invention relates to control method of air flow supplied to the combustion chamber, and to combustion chamber. The combustion chamber of the gas turbine contains casing with fuel pipeline for fuel supply to the casing, and carrying air pipeline for air supply to casing. Said combustion chamber also contains regulating system to regulate carrying air flow to the casing according to fuel characteristics. Fuel pipeline and air pipeline are connected with at least common nozzle. At least common nozzle is used both for fuel injection, and air injection. The regulating system is made with possibility to maintain fuel and air pulse essentially permanent. The regulating system contains sensor to measure fuel characteristic, throttle vale connected with air pipeline, control box to control the throttle valve based on the fuel characteristic measured by sensor.EFFECT: correction of mixed quantities of fuel and air, reduced discharges and effective work, in case, when fuel composition varies with time.10 cl, 5 dwg |
