Abstract
A burner head for a gas burner for improved flame stability and burner turndown is positioned in a longitudinally extending blast tube with an open end. The burner head includes a first surface facing in a direction transverse to the longitudinally extending blast tube and toward the open end, a second surface facing a direction transverse to the longitudinally extending blast tube and away from the open end and a third surface extending between the first and second surfaces. A first plurality of gas ports extends through the third surface, and a first passageway extends from the first surface to the second surface and is adapted to allow air to pass therethrough. A flame rod extends through the first passageway and into the flame zone.
