Abstract

The invention discloses a low NO.sub.x emission burner for use with an apparatus in which the material or materials are heated by the heat radiated from the radiation surface which is heated by the combustion by the burners. The secondary air injection ports or outlets are so arranged as to inject the secondary air upon the radiation surface to control the combustion, thereby reducing the release of NO.sub.x without producing CO and soot.
