METHOD OF REGULATING FUEL SUPPLY TO GAS TURBINE ENGINE Russian patent published in 2018 - IPC F02C9/26 

FIELD: motors and pumps.

SUBSTANCE: invention relates to the field of gas turbine engine construction, namely combustion chambers of gas turbine engines, mainly low-emission combustion chambers, and allows to increase the fuel efficiency of the completeness of combustion of the gas turbine engine fuel, in such modes of operation of the combustion chamber, when due to an unfavorable combination of fuel parameters in the combustion zone behind a part or all of the burners, the completeness of combustion of the fuel is reduced. Before feeding into the combustion chamber, the fuel is preheated in the preheater in the preheater, and the degree of heating of the fuel for its complete combustion is determined and controlled in the automatic engine control system, where from the gas analyzer there are readings of emission of one or several products of underburn – carbon monoxide – CO and unburned hydrocarbons – CnHm, and if the emission reading of one or several unheated products – carbon monoxide – CO and unburned hydrocarbons – CnHm is exceeded, a signal is received from the automatic control system to heat the fuel.

EFFECT: reduction of the ignition delay time and increase in the combustion rate by metered heating of the fuel.
