  • Patent number: 8529250
    Abstract: There is provided a system and method for heating at least one workpiece in a furnace by which the workpiece is heated by heating facilities. An exemplary method comprises heating a complete workpiece with the heating facilities. The exemplary method also comprises moving the workpiece out of the furnace such that a first portion of the workpiece is still inside the furnace while a second portion of the workpiece is outside the furnace and holding the workpiece at this position for a predetermined time period. Finally, the exemplary method comprises moving the complete workpiece out of the furnace.

  • Publication number: 20080156237
    Abstract: The combustor for solid particulate fuels is particularly well suited for burning shelled corn, but is also capable of burning other solid particulate fuels as desired, with no modification required for their use. The combustor includes a rotary agitator extending across the combustor chamber or “burning pot,” with the agitator having a plurality of radial arms. Combustion air passes through the hollow agitator shaft outwardly through the hollow arms, the arms distributing combustion air into the fuel mass as the arms rotate therethrough to produce more efficient combustion of the fuel and thereby reduce coagulation of partially burned corn on the internal surfaces of the combustor. The opposed walls of the combustor include at least one pivotally mounted wall, with the angle of that wall being adjustable to adjust the ash dispersal gap between the pivoting wall and the opposite wall.

  • Patent number: 7288742
    Abstract: According to a method and a device for heating a strip-shaped carrier in an oven, a carrier is passed through the oven in a direction of conveyance. The carrier is supported by a heatable plate, which together with the carrier is moved through the oven stepwise with a predetermined step size from a starting position to an end position.

  • Patent number: 6252202
    Abstract: A furnace is provided generally including an upper heating chamber and a lower work base or firing platform. The upper chamber provides the main source of heat to the materials to be heat-treated. The upper chamber contains a muffle within which is located a heater ring assembly. The heater ring assembly is located in the middle to upper half of the muffle and includes an annular heating element that is located between an outer insulation ring and an inner quartz sleeve. A cavity or channel extends through the muffle into which insulation materials and the heater ring assembly is located. The channel area in the muffle below the heater ring assembly allows for the placement of the firing platform therein. The firing platform includes insulation material and a heating element located in the upper portion thereof.

  • Patent number: 5743728
    Abstract: A method and system for calcining gypsum to recover gypsum in a form consisting essentially of calcium sulfate anhydrite is disclosed. The method includes the steps of feeding the ground gypsum material into a first kettle and heating the ground gypsum in the first kettle to the first predetermined temperature. The first predetermined temperature is preferably below 400.degree. F. so that the gypsum will still contain a sufficient amount of chemically-combined water so that it will self-fluidize by release of water vapor so that it will flow through the apparatus. The ground gypsum is then overflowed through at least one subsequent stage and heated to a final predetermined temperature to produce an anhydrite product. To produce insoluble calcium anhydrite or dead burn material, the final predetermined temperature is greater than 900.degree. F. and preferably within the range of about 900.degree. F.-1300.degree. F.

  • Patent number: 4874311
    Abstract: A method and apparatus for improving the performance of a regenerative burner has a combustion chamber which receives and combusts controllable amounts of auxiliary fuel, an oxidizing gas, and possibly air to form hot combustion products. A controllable amount of a main fuel is then delivered to the combustion chamber and is pyrolyzed by the hot combustion products to produce a hot flame. By controlling the flame, one can maintain optimal temperature of the combustion air passing through the flame. Sensing means and computing means allow for automatic adjustments of fuel, oxygen and air flow to further maintain optimal combustion air temperatures.
