FIELD: power engineering.
SUBSTANCE: low-toxicity burner comprises a housing with a rod for fuel supply to the main and standby burning zones, a turbuliser ridge located in front of the axial swirler of the mixer, provided in the hollow blades whereof are holes for fuel supply, a central body with channels for fuel and air supply to the nozzle of the standby zone. Slots or protrusions are made on the outer surface of the central body evenly along the circumference in the immediate vicinity of the output edge, primarily in the shape of a spherical segment. Slots or protrusions are made on the blades of the swirler evenly along the height of the blades in the immediate vicinity of the output edges, primarily in the shape of a spherical segment. The slots or protrusions made in two or more rows are located in a staggered order.
EFFECT: reduction in the content of atmospheric pollutants in the exhaust gases in all operating modes of the gas turbine plant, increase in the reliability of the burner.
