  • Publication number: 20050196011
    Abstract: An electric wire in a rising part, which is obtained by covering a conductor whose sectional shape is a square with an insulating film, is formed in a curve so that the inside of the curve is along the circumference of a circle having a radius “r” until the electric wire risen from the coil in which the electric wire is wound is turned in a desired direction. The radius “r” of the circle has a length, which is equal to or larger than ½ of one side R of the square as the sectional shape of the conductor of the electric wire.

  • Patent number: 6463864
    Abstract: A gasification and melting furnace for wastes has a vertically movable furnace center lance disposed along the axis of the furnace and adapted to blow off a combustion sustaining gas downward into the furnace. One or more stages of upper tuyeres are disposed so that the angle at which the combustion sustaining gas is blown off into the furnace is displaced from the furnace axis direction, and one or more stages of lower tuyeres projected into the furnace so as to blow off a combustion sustaining gas or both combustion sustaining gas and fuel toward the furnace axis. Formation of a low temperature region in the furnace are prevented and a fire spot is concentrated on the combustion of wastes. As a result, molten slag and various metals, as well as an energy gas, which are high in added value, can be recovered stably.

  • Publication number: 20020033123
    Abstract: By using a gasification and melting furnace for wastes having a vertically movable furnace center lance disposed along the axis of the furnace and adapted to blow off a combustion sustaining gas downward into the furnace, one or more stages of upper tuyeres disposed so that the angle at which the combustion sustaining gas is blown off into the furnace is displaced from the furnace axis direction, and one or more stages of lower tuyeres projected into the furnace so as to blow off a combustion sustaining gas or both combustion sustaining gas and fuel toward the furnace axis, it is possible to prevent the formation of a low temperature region in the furnace and concentrate a fire spot for the combustion of wastes. As a result, molten slag and various metals, as well as an energy gas, which are high in added value, can be recovered stably.
