FIELD: heating systems.
SUBSTANCE: invention refers to gas burners with separate air and gaseous fuel supply. The effect is achieved in gas burner (1) containing main metal housing (6), an inner tube for fuel gas, at least two outer tubes (10) for fuel gas, single tube (8) for supplying pre-heated air, fuel gas supply control system, refractory block (30) and a group of nozzles (20) which are located in a circumferential direction coaxially in relation to inner tube and meant for spraying pre-heated air into combustion chamber.
EFFECT: limit reduction of NOx concentration in exit combustion products.
