METHOD FOR REDUCING EMISSIONS OF HARMFUL SUBSTANCES IN GAS TURBINE ENGINE

摘要

FIELD: engines.SUBSTANCE: invention relates to aircraft engineering and can be used to control a gas turbine engine. Method of reducing emissions of harmful substances comprises additionally measuring fuel pressure in standby Rtand main Rtcombustion zones, calculating ratio Rt/Rt, comparing measured values of emissions of harmful substances with maximum allowable values and correcting pressure ratio Rt/Rtby reducing fuel supply into standby combustion zone until level of harmful emissions is 1-2 % lower than maximum permissible values.EFFECT: invention improves ecological indices of emissions of harmful substances during operation of gas turbine engine.1 cl, 1 dwg
