METHOD AND DEVICE FOR CONTROLLING FUEL SEPARATION IN THE COMBUSTION CHAMBER Russian patent published in 2018 - IPC F02C9/34 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering. Method for determining the fuel separation setpoint used to adjust the fuel separation setpoint for the combustion chamber, contains the following stages: output of the first element of information associated with the calorific value of the main fuel supplied; output of the second information element associated with the operating state of the combustion chamber; output of at least one third information element representing combustion stability in the combustion chamber; selection of a predetermined pair of curves, minimum and maximum boundary curves for the fuel separation setting parameter from a plurality of predetermined pairs of boundary curves based on the first information element and the second information element. In this case, the pairs of the minimum and maximum boundary curves determine the band of the fuel separation parameters, permissible for the range of values of the second information element; determination of the fuel separation setpoint within the selected pair of minimum and maximum boundary curves based on the third information element, wherein the said specific fuel separation setpoint is used to adjust the fuel separation setting parameter for the combustion chamber. Method is implemented by the control unit.

EFFECT: invention makes it possible to improve the reliability of the gas turbine engine.
