FIELD: power engineering.
SUBSTANCE: burner has body 10 attached to outlet unit 42 and fuel duct 12 passing through body 10 to fuel nozzle 22 that functions to inject fuel to burner throat 40. Jets 20 are configured for primary air injection to primary combustion zone 24 which is usually found in throat 40. Disk with surface 28 is joined to throat 40 and runs at certain divergence angle relative to center line 35 of burner. Jets 34 communicate with air duct 14; they are passed through outlet unit 42 and inject secondary air to secondary combustion zone 38 that can be found on disk surface 28 or on hot surface 30 of burner.
EFFECT: reduced emission of pollutants.
