  • Dual mixing gas burner
    Patent number: 5112219
    Abstract: A dual mixing gas burner comprises a cylindrical or other shaped housing having a flat front burner surface and a flat rear surface. A fuel gas chamber and two oxygen chambers are located within the housing. A central oxygen jet conveys oxygen gas from the first oxygen chamber to the front burner surface. A fuel gas jet, coaxially positioned with and surrounding the central oxygen jet, conveys fuel gas from the fuel gas chamber to an annular area on the front burner surface around the central oxygen jet. An outer oxygen jet, coaxially positioned with and surrounding the fuel gas jet, conveys oxygen gas from the second oxygen chamber to an annular area on the front burner surface around the fuel gas jet. Any number of the above combinations of a central oxygen jet, fuel gas jet, and outer oxygen jet may be provided to convey oxygen gas and fuel gas to the front burner surface.
