  • Publication number: 20230400254
    Abstract: A method and a control device for operating a furnace, in particular an anode furnace, formed by a plurality of heating channels and furnace chambers, the furnace chambers serving to receive carbonaceous products, in particular anodes, and the heating channels serving to control the temperature of the furnace chambers. The furnace includes at least one furnace unit that contains a heating zone, a fire zone and a cooling zone, which for their part are formed by at least one section that has furnace chambers. A suction ramp of the furnace unit is disposed in a section of the heating zone, and a burner ramp of the furnace unit is disposed in a section of the fire zone. Process air in the heating channels of the fire zone is heated by the burner ramp, and exhaust gas is suctioned from the heating channels of the heating zone by the suction ramp, while operation of the ramps is controlled by a control device of the furnace unit.

  • Patent number: 9714791
    Abstract: A method and to a control device 10 for operating an anode furnace including an extraction ramp arranged in a section of a heat-up zone and a burner ramp arranged in a section of a firing zone of the furnace unit, wherein operation of ramps is controlled by means of a control device of the furnace unit, wherein the ramps each have a read unit, wherein the section each have at least one stationary transponder unit, wherein the read units of the ramps communicate with the transponder units of the sections in which the ramps are arranged, wherein the respective transponder units are identified by means of the control device, and wherein a respective position of the ramps is determined by allocating the ramps to the respective transponder units.
