FIELD: power engineering.
SUBSTANCE: method to control combustion in a gas turbine and the appropriate device includes stages, where they measure, by means of one or two calorimeters, temperature, calorific power and relative density of gaseous fuel, in order to detect Wobbe number, the measured value of the Wobbe number is compared with the specified value of the Wobbe number for gaseous fuel, and temperature of gaseous fuel is controlled by at least one heat exchanger, in order to achieve the specified value of the Wobbe number. They may also include the stage, when the second gaseous fuel is used, with the Wobbe number differing from the gaseous fuel, or fuel received by mixing of the gaseous fuel and the second gaseous fuel, according to arbitrary proportions, and varying in time.
EFFECT: invention makes it possible to improve efficiency of gas turbine operation.
