ABSTRACT:
A burner having a primary flame zone and a secondary flame zone. The throat of the quarl in the center of the primary flame zone is provided with a gas nozzle supported by a swirl element. The orifices of the nozzle are radially and obliquely distributed so that the gas introduced via the frustoconical chamber mixed with the primary air to form a swirl current. The frustoconical chamber extends to the inner surface of the burner to form a circular extended section to restrain the width of the flame; the extended section is parallel to the secondary air inlets distributed on the burner body around the periphery of the frustoconical chamber to effectively control the formation of NOx during combustion.
