  • Method of controlling burners for heating liquid glass flow channels
    Patent number: 9046264
    Abstract: Methods and apparatus for controlling the operation of a burner used for heating liquid glass feeders of a glass furnace. A burner is supplied with a fuel and oxygen. An additional gas is injected so that the sum of the oxygen flow, the fuel flow and the additional gas flow is greater than a minimum cooling flow for the burner.
    Type: Grant

  • Oven and oxy-combustible method for melting vitrifiable materials
    Patent number: 8336335
    Abstract: The invention relates to a method for melting vitrifiable materials in a low-capacity oven, wherein at least part of the melting energy is supplied by two oxy-burners projecting into the melting chamber through the upstream wall and arranged on opposite sides of a vertical plane in which a longitudinal axis of the melting chamber is situated, in such a way as to create two flames, the respective injection axes thereof crossing at a distance from the upstream wall, between ? and ¾ of the length L of the melting chamber.

  • Method And Device For Manufacturing A Structured Lining Wave, And Such A Lining Wave
    Publication number: 20110229689
    Abstract: According to this method, a strip is folded and stamped in successive steps by means of two opposing blocks that move alternately toward and away from each other, these blocks having textured active surfaces that are not conjugate with the two surfaces of the corrugation, and the surface of the strip is textured before the folding and stamping are carried out. The invention can be used for air distillation columns.
