20100159409 | NON-CENTRIC OXY-FUEL BURNER FOR GLASS MELTING SYSTEMS - A burner for use in a combustion chamber of a furnace or a forehearth includes a gas delivery member for delivering a gaseous oxidant, a fuel delivery member for delivering a fuel and having a portion disposed at an interior of the gas delivery member and offset from a longitudinal axis of the gas delivery member, and a flange assembly mechanically associated with the gas and fuel delivery members, the flange assembly adapted for rotational movement to releasably secure the gas and fuel delivery members with respect to each other to provide a flame footprint at a select location in the combustion chamber. | 06-24-2010 |
20100162761 | FLAME POLISHING OF FLAT GLASS - A method and apparatus are provided to flame polish a thin glass sheet which includes cooling the thin glass sheet followed by heating the thin glass sheet with an intense flame to substantially reduce if not eliminate surface roughness of the glass sheet. | 07-01-2010 |
20100167219 | BURNER BLOCK FOR PRODUCING FLAT FLAME - A burner and process for a melter is provided which includes a combustion stream transitioning from an elliptical cross section to a circular cross section to provide a flat flame from the circular cross section for combustion in the melter. | 07-01-2010 |
20100233639 | BURNER FOR REDUCING WALL WEAR IN A MELTER - A combustion gas flow for an atmosphere of a melter includes a first gas flow at a first velocity introduced into the atmosphere, and a second gas flow at a second velocity less than the first velocity introduced into the atmosphere for entraining corrosive or condensable vapors in the atmosphere and shrouding and inhibiting the first gas flow from entraining condensable or corrosive vapors at a higher rate than the second gas flow. | 09-16-2010 |
20100242545 | CYCLICAL STOICHIOMETRIC VARIATION OF OXY-FUEL BURNERS IN GLASS FURNACES - An end-port regenerative furnace includes a housing; a combustion chamber within the housing; first and second regenerators each disposed to be in communication with the combustion chamber; and first and second burner assemblies adapted to operate fuel-rich and fuel-lean concurrent with a respective one of the first and second regenerators, the first and second regenerators each constructed and arranged to alternate between a combustion mode and an exhaust mode for the combustion products circulating in the combustion chamber. | 09-30-2010 |
20100307196 | BURNER INJECTION SYSTEM FOR GLASS MELTING - A burner for melting glass forming batch material includes a burner assembly constructed and arranged with a first passage for providing a fuel stream and a second passage for providing an oxidant stream, the first and second streams coacting to produce a supersonic combustion jet flame penetrable into glass melt. A method for melting glass forming batch material is also provided and includes providing a fuel stream; providing an oxidant stream; mixing the fuel and oxidant streams with sufficient force for providing a supersonic combustion jet flame; directing the supersonic combustion jet flame to contact the glass forming batch material; and penetrating the glass forming batch material to a select depth with the supersonic combustion jet flame. | 12-09-2010 |
20110011134 | INJECTOR FOR HYDROGEN AND OXYGEN BUBBLING IN GLASS BATHS - A bubbler for injecting gas bubbles into a glass bath in a melter includes an injector mounted to a bottom portion of the melter beneath the glass bath, the injector having a surface exposed to the glass bath; a plurality of passageways formed in the injector extending through the injector and opening at the surface for providing the gas bubbles into the glass bath; and a controller connected to the bubbler for controlling origination and release of the gas bubbles for injection into the glass bath. | 01-20-2011 |
20120192773 | METHODS AND APPARATUS FOR CARBON DIOXIDE-OXYGEN-COAL COMBUSTION - A burner and method for oxidizing solid fuels wherein the burner has a lance having one or more nozzle feeds and one or more nozzle outlets concentrically surrounded by a primary oxidant passage which is concentrically surrounded by a secondary oxidant passage wherein the primary and secondary oxidant passages communicate at their proximal ends with a gas supply, the lance having a distal and proximal end and the one or more nozzle feeds is in communication with a gas supply. | 08-02-2012 |
20120214115 | METHOD FOR HEATING A BLAST FURNACE STOVE - A method for heating a blast furnace stove by combusting in a stable, visible flame a fuel with a lower heating value (LHV) of 9 MJ/Nm | 08-23-2012 |
20120214116 | APPARATUS AND METHOD FOR HEATING A BLAST FURNACE STOVE - A method for heating a blast furnace stove includes combusting fuel in a combustion chamber in the stove, providing combustion gases from the combustion chamber to heat refractory material in the stove, recirculating exhausted combustion gases into the combustion chamber, enriching the combustion chamber with oxygen sufficient for maintaining combustion in the combustion chamber without damaging the refractory material in the stove. | 08-23-2012 |
