Abstract

A burner construction having wall means defining a chamber for receiving fuel from a source thereof, the wall means having a plurality of port means passing therethrough and interconnecting the exterior of the wall means with the chamber whereby fuel will issue from the chamber out through the port means. The port means are arranged in a pattern through the wall means to define a first row of aligned spaced port means and a plurality of second rows of aligned spaced port means transverse and adjacent to the first row in spaced parallel relation to each other with the spacing between adjacent second rows being greater than the spacing between adjacent port means in the first row so that secondary air will be provided in a sufficient amount for all of the port means of the burner construction for proper fuel combustion.

Claims

1. In an apparatus having a cooking chamber, a source of fuel and means for igniting said fuel, the improvement comprising a burner construction for heating said cooking chamber and having wall means defining chamber means for receiving fuel from said source thereof, said wall means having a plurality of port means passing therethrough and interconnecting the exterior of said wall means with said chamber means whereby fuel will issue from said chamber means out through said port means to be ignited by said means for igniting said fuel, said port means being arranged in a pattern through said wall means to define a straight line first row of aligned spaced port means and a plurality of straight line second rows of aligned spaced port means perpendicular to and crossing said first row and in spaced parallel relation to each other with the spacing between adjacent second rows being greater than the spacings between adjacent port means in said first row, the central port means of each second row providing one of the port means of said first row, the number of second rows being such that a plurality of straight line unported sections of said wall means respectively defined between adjacent pairs of said second rows lead perpendicularly to said first row to provide secondary air therefor.

2. In an apparatus as set forth in claim 1, said wall means defining a tubular structure having a substantially circular cross-sectional configuration, said first row of port means extending longitudinally along said tubular structuRe.

3. In an apparatus as set forth in claim 2, said first row extending along the top of said tubular structure.

4. In an apparatus as set forth in claim 3, each port means comprising a pair of spaced and cooperating ports passing through said wall means, each port including a tab means having a free end projecting into said chamber means beyond the interior surface of said wall means and having another end attached to said wall means on the side of its respective port that is adjacent to the tab means attached side of the other port that forms said respective pair of ports, said tab means and said ports being so constructed and arranged that fuel is adapted to flow from said chamber means in two streams respectively out of each pair of cooperating ports and impinge against each other to form a substantially common stream that is angularly disposed relative to said wall means.

5. In an apparatus as set forth in claim 4, the spacing between adjacent second rows of port means being such that said second rows cross said first row at every other pair of cooperating ports of said first row.
