A gas burner adapted to discharge said fuel at its the periphery for combustion, includes upper and lower concave plates secured together to define a chamber and an outer periphery having a plurality of burner ports. The upper plate preferably has a periphery extending radially at least as far as the lower plate. The periphery of the upper plate is downwardly angled, preferably more steeply than the periphery of the lower plate. The peripheral edge of at least one or the other of the top or bottom burner plates extends radially outwardly from the central axis a distance beyond the location of the burner ports and into the path of burning gases issuing from the ports whereby the temperature of said burning gases is reduced. Preferably, the periphery of the upper plate extends downwardly to an elevation below the upper edges of the burner ports, so that gases emerging from the ports are caused to impinge against the periphery, thus cooling the gases and thereby reducing the NO.sub.X content of the combustion gases.

[ What is claimed is:] [1.] A gas burner adapted to receive fuel gas from a gas intake conduit and to discharge said fuel at a periphery of said burner for combustion, said burner including upper and lower concave plates secured together to define a plurality of burner ports, said burner having a central axis,a chamber between said upper and lower plates for receiving fuel and issuing said fuel outwardly through said ports,said lower plate having an opening for receiving fuel into said chamber, and a peripheral edge spaced radially from said central axis,said upper plate being imperforate and having a peripheral edge spaced radially from said central axis,said peripheral edge of said top plate spaced radially outwardly from said central axis a distance beyond the location of said burner ports and extending into the path of burning gases issuing radially outwardly from said ports whereby the temperature of said burning gases is reduced.
