FIELD: power engineering.
SUBSTANCE: invention relates to power engineering. Industrial burner that features low levels of contaminants emission is suitable for use in thermal furnaces for treatment of billets at free atmosphere. Said burner can create compact and lean flame at low emission of NOx at whatever temperature of the chamber and whatever air excess for support of combustion. This burner incorporates separate air inlet to support combustion and separated combustible gas inlet.
EFFECT: separation of the main combustion process into three stages, circulation of flue gases and depletion of some reagents.
