METHOD FOR REDUCING EMISSIONS OF HARMFUL SUBSTANCES IN GAS TURBINE ENGINE Russian patent published in 2016 - IPC F02C9/28

Abstract RU 2596901 C1

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 Rt₁ and main Rt₂ combustion zones, calculating ratio Rt₁/Rt₂, comparing measured values of emissions of harmful substances with maximum allowable values and correcting pressure ratio Rt₁/Rt₂ by 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.
