GAS-TURBINE ENGINE COMBUSTION CHAMBER OPERATIONAL CONTROL METHOD Russian patent published in 2017 - IPC F23R3/26 F02C3/13 F02C9/18 

FIELD: electricity-producing industry.

SUBSTANCE: there is a gas-turbine engine combustion chamber operational control method, where the engine is composed of the compressor, two burners, the combustion chamber, which is located downstream of the noted burners, the turbine, two temperature probes downstream of the noted combustion chamber. Upon that, there is one vent for the part of the oxygen-containing gas withdrawal placed downstream of the noted compressor and upstream of the noted combustion chamber. Along with this, the noted vent is a part of the system of the oxygen-containing gas bypass in contravention of the combustion chamber and has a valve for the amount of the bypassing gas regulation. The method comprises stages, where one controls the combustion products temperature, compares the noted temperature probes value, opens the noted valve or increases the rate of its opening in case if in consequence of the noted comparison one find out that the difference between the noted temperature probes value goes beyond the fixed limit of the temperature differential.

EFFECT: invention allows to reduce the probability of occurrence of high carbon monoxide emissions by virtue of the vent valve position automatic control.
