FIELD: machine building.
SUBSTANCE: tubular injector for fuel injection into combustion chamber of gas turbine includes: coaxial first cylindrical housing and second cylindrical housing; nozzle connected to corresponding first ends of first cylindrical housing and second cylindrical housing; a guide bushing installed on the first cylindrical housing to allow relative axial sliding of the first cylindrical housing relative to the second cylindrical housing due to expansion and compression; and sealing elements between first cylindrical housing and guide bushing. Sealing elements are formed by at least two O-rings, and the first cylindrical body and the guide bushing are separated by an annular gap except for the location of O-rings. Also disclosed is a gas turbine burner comprising a tubular injector.
EFFECT: invention prevents plugging of internal channels for injector fluid medium, as a result of which machine efficiency is increased, as well as emissions of pollutants are reduced.
