FIELD: engines and pumps.
SUBSTANCE: burner of gas turbine engine includes swirler and gas injector for fuel injection to air flow in the burner swirler. At that, at least one gas injector has the possibility of being located in swirler channel inlet. Gas injector includes at least one fuel tube. Tube is provided with multiple diffuser holes distributed along the tube and used as gas injectors for effective fuel distribution in air flow passing via the tube. Gas injector tube has circular or spiral V-shaped grooves along its external surface. Diffuser holes have the possibility of being located in lower part of grooves.
EFFECT: invention improves the burner air and fuel mixing efficiency.
