ABSTRACT:
A low NO.sub.x atmospheric gas burner is provided, which includes at least one burner tube having a plurality of gas outlet orifices terminating in a burner bed, and a plurality of plates disposed above the burner tube within the reach of the flame, which plates lower the temperature and effect a stepped combustion. According to the invention, the plates extend parallel to, and on opposite sides of, the orifices provided in the burner tube, and the orifices are arranged in a line parallel to the burner axis. The plates are connected direct to the burner tube substantially throughout the entire length of their lower edges.
