  • Patent number: 6101847
    Abstract: A method for melting and refining glass, such as E glass, comprises feeding glass batch materials into a melting and refining tank for melting and refining the glass batch materials into glass and a forehearth, downstream of the tank, for further refining the glass and delivering the glass to fiberizing means. The melting and refining tank is heated with oxygen fired burners. The oxygen fired burners in the melting and refining tank are located in the sidewalls at the upstream end of the tank and extend for about one-third, one-half or two-thirds the length of the tank. In one embodiment, burners are also located in the upstream end wall. This arrangement of the oxygen fired burners at the upstream end of the melting and refining tank moves the melter hot spot upstream for better refining of the glass and enables the furnace to produce a higher output of glass than can be obtained in a conventional E glass furnace of the same size.

  • Patent number: 5955011
    Abstract: Fine fibers are formed and carried in a high energy, high temperature gaseous stream to a primary fine fiber collection surface where fine fibers are collected from the gaseous stream. Gases of the gaseous stream along with fine fibers not removed from the gaseous stream by the primary collection surface are drawn through the primary collection surface and formed into an exhaust gas stream which is passed through a secondary fine fiber collection surface to remove additional fibers from the exhaust gas stream before it is discharged to the atmosphere. To reduce the operating temperatures at and surrounding the primary and secondary collection surfaces, the gas streams are cooled by evaporative cooling. Water is sprayed into the gas streams by nozzles, shielded from the gas streams by scoops, so that fibers do not collect on the nozzles and form fiber wads.

  • Patent number: 5659564
    Abstract: The bottoms of exhaust stacks and systems on glass melting furnaces usually collect slag that is produced by volatiles in the exhaust gases condensing out and forming a glassy substance on the cooler walls of the stacks, etc. which then runs down the walls picking up refractory and forming a slag in the lowest places. This slag often cools to hardness or a high viscosity, tough mass. It has to be removed periodically to prevent building up to the point that slag would run back into the furnace damaging the glass and removal is a hot, dirty, time consuming job. This problem is worse on oxy-fuel furnaces which the industry is trending towards for other advantages. The present invention eliminates this problem by reducing the size of the reservoir in the bottom of the stack and adding a heated bushing with an orifice that continually drains the slag from the small reservoir.

  • Patent number: 5643348
    Abstract: An oxygen-fuel firing system for a furnace comprising separate, spread apart nozzles for introducing gaseous streams of oxygen and fuel into the furnace at spaced apart locations. The gaseous streams merge within the furnace away from the furnace walls and crown. Thus, the main combustion within the furnace takes place in the central portion of the furnace where a broad flame cloud is created. The broad flame cloud provides a more uniform temperature profile within the furnace for a more efficient processing of materials being melted in the furnace.

  • Patent number: 5639291
    Abstract: In a method of and an apparatus for forming composite and other fibers, individual filaments from two or more sets of continuous primary filaments of two or more heat-softenable fiberizable materials are brought together lengthwise to form pairs of continuous primary filaments. The groupings of continuous primary filaments are fed into a high energy attenuation blast where the filaments are heated, attenuated and formed into composite or other staple fibers of the heat-softenable fiberizable materials. Preferably, the individual continuous primary filaments of the groupings of continuous primary filaments are fused, adhesively bonded or otherwise joined together, prior to being introduced into the high energy attenuation blast, to prevent the individual primary filaments of the groupings of continuous primary filaments from separating in the high energy attenuation blast.

  • Patent number: 5634954
    Abstract: Air filtration media is formed by collecting a layer of fine diameter glass fibers directly on a foraminous, reinforcing, backing layer and subsequently collecting a layer of relatively coarse diameter glass fibers directly on the layer of fine diameter glass fibers. A bonding agent carried by the glass fibers is then cured to bond the glass fibers within each layer together at their points of intersection, to bond the layers of fine and coarse glass fibers together and to bond the layer of fine diameter fibers to the backing layer. This method of forming the composite air filtration media permits the particle efficiency and the dirt loading capacity of the composite air filtration media to be adjusted during the production of the media by adjusting the diameters of the glass fibers in one or both of the layers and/or by adjusting the density of one or both of the layers.

  • Patent number: 5620493
    Abstract: Disclosed is an improved device and method for detecting fiber breakouts and fiber restarts in processes or systems for making fibers from a molten thermoplastic material. In these processes the running fibers induce ambient air into the array of hot fibers close to the nozzles where the fibers are formed, but this air flow essentially ceases when the fiber breaks out. A thermocouple junction located in the path of this airflow will sense temperature changes caused by fiber breakouts and fiber starts. The present invention simplifies and increases the accuracy of prior art sensor systems by eliminating hardware holding this thermocouple and instead uses one or more small holes in a bushing frame plus the refractory used to hold the fiberizing bushing in the frame to hold the thermocouple in the appropriate place.
