FIELD: machine building.
SUBSTANCE: gas turbine combustion chamber comprises a compressor which is upstream in relation to the combustion chamber, the method comprises fuel supply to the combustion chamber; receiving a property value for at least one physical property (PT8, PT7, Tinlet, THBOV) of air used for fuel combustion in the combustion chamber; heat (HIengmodel) estimation of fuel supplied to the combustion chamber based on the property value; caloric value measurement (LCVmea) of the fuel which is upstream in relation to the combustion chamber; adjustment of an estimated heat (HIengmodel) based on the measured calorie value (LCVmea); and control of the fuel valve that regulates the fuel supply to the combustion chamber based on the adjusted estimated heat (HIexpected) and the required heat (FFDEM).
EFFECT: provision of the gas turbine stable operation.
