FIELD: mechanical engineering; gas turbines.
SUBSTANCE: proposed main device of gas turbine for injecting liquid fuel for one combustion chamber 10 provided with preliminary mixing chamber has group of channels for injecting liquid fuel distributed inside preliminary mixing chamber 12 and group of blades receding in radial direction relative to symmetry axis of combustion chamber. Group of blades has passages for cooling air surrounding channels for delivery of liquid fuel and cooling the channels to prevent deposition of carbon on surfaces of blades. Each blade is provided at least on one side surface with one channel for injecting liquid and at least one cooling air injection point.
EFFECT: reduced discharge of substances polluting ambient atmosphere, increased stability of flame and reduced pressure fluctuations in combustion chamber.
