20130011805 | PROCESS OF OPERATING A GLASS MELTING OVEN - A combustion method for melting glass in which two fuels of the same nature or different natures are fed into a fusion furnace at two locations remote from each other for distributing the fuel to reduce NOx emissions. The combustion air is supplied at only one of the locations. In a method for operating a glass melting furnace, the fuel injection is distributed to reduce NOx emissions. The furnace includes a melting vessel for receiving the glass to be melted and containing a bath of molten glass, walls defining the furnace, a hot combustion air inlet, a hot smoke outlet, at least one burner for injecting a first fuel, and at least one injector for injecting a second fuel. The injector has an adjustable flow complementary relative to the flow to the burner so that up to | 01-10-2013 |
20120231398 | RADIATING BURNER HAVING ENHANCED PERFORMANCE AND METHOD FOR IMPROVING THE PERFORMANCE OF A RADIATING BURNER - A method for improving the performance of a radiating burner designed to be supplied during operation by means of a flow (F) comprising a mixture of air and combustible gas. The burner includes a body defining a combustion chamber and provided with an inlet for the mixture; a porous wicking agent closes off the chamber in a non-sealing manner and is arranged downstream of the inlet in the direction of flow (F) of the mixture; and a distribution grid is arranged between the mixture inlet and the wicking agent. The method includes creating an electric field in the combustion chamber by applying an electric potential difference of at least 5 kV between the wicking agent and the distribution grid. | 09-13-2012 |

20100213647 | PROCESS AND INSTALLATION FOR HEATING A METALLIC STRIP, NOTABLY FOR AN ANNEALING - The invention pertains to the heating of a metal strip, and relates to equipment for heating a metal strip that comprises a pre-heating housing provided with a device for projecting hot gases towards the strip, a heating housing with regenerative burners, a duct for discharging the gases from the heating housing, a three-way adjustable valve and an adjustment device including a sensor for detecting the setpoint temperature of the metal strip and a member for adjusting the three-way valve so that it can adjust the amount of hot gases fed to the projection device. The invention can be used in equipment for heating narrow strips before annealing the same. | 08-26-2010 |
20100200086 | AUTOMATICALLY TRIPPED COMPACT SAFETY DEVICE FOR CONTROLLING THE FLOW OF A FLUID - The disclosure relates to a safety device to be inserted in a pipe through which a fluid flows from an upstream side to a downstream side, this device comprising a tube offering the fluid a central flow path controlled by a central valve which closes in the event of excessive flow of this fluid, an elastically deformable annular shutter mounted on the external periphery of the tube, and retention clamps. According to the disclosure, each of the clamps has a tied end fastened to the periphery of the tube upstream of the annular shutter and can adopt, under the effect of a radial compression, a folded configuration in which its free end is turned towards this annular shutter. | 08-12-2010 |
20100057261 | METHOD AND DEVICE FOR PROCESSING AND STORING DATA - A method and a device for processing and storing data generated in a fluid flow station, the data being read and put into a volatile memory allocated to a communicating module of the flow station. The data are analyzed according to predetermined relevancy criteria to select data corresponding to a type of event, and the selected data are analyzed according to a redundancy criterion to detect data having the same value during two successive readings. The data having a value unchanged in relation to the value of the previous reading are replaced by a mark and the data thereby compressed are stored in a non-volatile memory. | 03-04-2010 |
