  • Patent number: 8776546
    Abstract: An air distillation unit comprises an air distillation column (10) suitable for producing a nominal flow of gaseous nitrogen, the top of said column being connected to a liquid nitrogen source (8), and operates by carrying out the following steps: a flow of compressed, cooled and purified air is sent to an exchanger (11) and then to the column, a flow of gaseous nitrogen is withdrawn from the column, the level of liquid at the bottom of the column is controlled; and injection liquid (20), sent from the source to the column, is no longer sent if the required production reduces to at most the nominal production. Application to the separation of air by cryogenic distillation.

  • Patent number: 6688876
    Abstract: A process for combustion with the aid of a liquid fuel and a gaseous oxidizer containing from 20% to 100% volume of oxygen, in which the fuel is injected with the aid of an injector. The injector, which has a height “d”, is placed inside a glory hole. The glory hole has a height “D” at the end thereof corresponding to the ejection of the gaseous mixture towards the zone of heating of a charge. A coefficient “S” in the following equation is maintained at a value less than or equal to 1 for substantially the entire duration of combustion to ensure the stability of the flame.

  • Patent number: 6135366
    Abstract: The injector comprises a duct (31) through which a liquid fuel which forms a film lining its wall, and an atomizing fluid, are transmitted to its downstream part, from where the fuel is sprayed, forming a mist with the atomizing fluid.The downstream part has, from the duct (31) towards the free end of the injector, a chamber (32) for destabilizing the film which has a cross section that is larger than that of the duct, a throat (33) for detaching the film extending the destabilization chamber and having a cross section that is smaller than that of this chamber, and a spray orifice (34) which is open at the end of the injector, into which the throat opens, and which has a larger cross section.Use: heating furnaces, especially glass furnaces.

  • Patent number: 5779754
    Abstract: A process for melting glass in a horseshoe-flame furnace including a rear, a forward and a lateral wall and a longitudinal axis comprising the steps of: introducing a charge into a region of the rear wall of the furnace; running the charge, in succession in a longitudinal direction, through a melting zone to completely melt the charge and form a glass bath, through a homogenization zone and then through a refining zone; evacuating the melted and refined glass into a region of the forward wall of the furnace; sending an air-fuel flame from a first region in the rear wall which is staggered with respect to the longitudinal axis of the furnace, evacuating smoke from a second region of that same rear wall essentially symmetrically to the first region with respect to the axis; periodically alternating the first and second regions; and sending at least one oxidized fuel flame above the refining zone from a point on the lateral wail adjacent to the second region which is situated opposite the refining zone.
