Abstract

An atmospheric gas burner includes a burner ring having a plurality of gas outlet ducts defining a respective plurality of gas outlet openings and each having a center axis extending at an angle greater than 0° relative to a radius of the respective outlet opening, and a burner cover overlying the burner ring with the burner ring having a portion projecting beyond outer edges of lower regions of the gas outlet openings, and the burner cover having a portion which overhangs about the outer edges of upper regions of the gas outlet openings.

Claims

1. An atmospheric gas burner with premixing of primary air, comprising:

a burner ring having a plurality of gas outlet ducts defining a respective plurality of gas outlet openings having outer upper and lower edges, said outlet ducts each having a center axis extending at an angle greater than 0°

relative to a radius associated with a respective opening, and said burner ring having a portion projecting beyond the outer lower edges of said gas outlet openings;

a burner cover overlying said burner ring and having a portion which overhangs the outer upper edges of said gas outlet openings;

a burner support, said burner cover having at least one flow cone extending toward said burner support; and

whirling and cooling ribs arranged concentrically around said flow cone.
