20090032012 | Radiant Gas Burner Unit - An improved radiant gas burner unit is provided having a shallow base with long walls and shorter walls. The shallow base supports a radiant gas burner plate or plates having openings therethrough, and forming an external surface of the base for emitting high temperature gas radiation. At least three mixing tubes are provided aligned with the shorter wall, and having two open ends. The first open end is positioned within the base and the second open end is positioned adjacent corresponding openings formed through the long wall of the base. A gas supply line extends along the long wall and has gas outlets for ejecting gas across an open air gap positioned intermediate the gas outlet and the second open end of the mixing tubes. The ejected gas is mixed with air as it crosses the air gap, and is provided to the openings of the radiant gas burner plate for combustion which produces high temperature radiation on the radiant gas burner plate and external surface of the base. | 02-05-2009 |
