Abstract
A firebox for a gas grill with an infrared re-emitter surface at the top, at least one heat shield at the bottom, and sidewalls intermediate between the heat shields and the emitter plate forming a box like structure in which multiple small cross sectional area tubes with gas burner ports on the top or sides are disposed in an array between the heat shield and the emitter plate. The heat shield below the burner tubes has openings disposed below the burner tubes to admit secondary combustion air and provide cooling of the burner tubes preventing pre-ignition.
