Abstract
A burner for combusting fuel gas and air in an enclosure having a burner block member of non-combustible material, such as ceramic, having a central rectangular or square opening. Said burner block being located between the surface to be heated and an enclosure wall opposite said surface, said central rectangular or square block opening being used to shape the combustion flame in a flat or fan shaped fashion parallel to the enclosure wall surface. In such an arrangement, the burner's purpose is to direct combustion flame upon the enclosure wall which is heated by the flame and radiates heat back towards the surface area to be heated and to reduce the oxygen content which serves to reduce the peak flame temperature of the combustion process to thereby reducing NO.sub.x production.
