METHOD OF OPERATION OF GAS TURBINE IN MODE WITH PARTIAL LOAD AND GAS TURBINE Russian patent published in 2017 - IPC F02C9/18 F23R3/26 

FIELD: machine engineering.

SUBSTANCE: gas turbine has a compressor for air preparation, a combustion chamber with a burner and a turbine for pressure relief. A bypass flow channel is provided and designed to direct compressor air during operation of the gas turbine to the burner and to the hot gas flow generated in the combustion chamber. In this case, the cross-section of the opening of the bypass flow channel can be adjusted by means of a controlling element, the gap section change rate being selected such that the relative pressure loss in the combustion chamber or the temperature of the combustion chamber material are constant.

EFFECT: invention allows the partial load range to be lowered to create lower power levels without exceeding the carbon monoxide emission limit values.
