Embodiment Construction

[0026] In the drawing, an anode ring furnace 10 is shown, which is composed of a plurality of furnace units 11 according to certain rules. In the present embodiment, each furnace unit 11 comprises 12 furnace chambers 12, and these furnace chambers are composed of heating zones 13, combustion zones 14 and cooling zones 15 in different numbers. All furnace units 11 are of identical construction and have several slots 16 , each of which is bounded on both sides by a heating channel 17 as viewed in the longitudinal direction of the furnace unit 11 . The slots 16 are used to accommodate anodes, which extend in a direction perpendicular to the drawing plane and are sequentially accommodated in the slots 16 . The heating channels 17 of the oven chamber are fluidically connected to one another in the longitudinal direction of the oven unit 11 .

[0027] The furnace chamber 12 is provided with several different devices whose position relative to the furnace chamber 12 can be varied in...

Abstract

The invention relates to a method for heat recovery in the production of anodes in an annular anode furnace (10), comprising at least one furnace unit ('hearth') (11) with a heating zone (13), a hearth zone (14) and a cooling zone (15), with in each case a plurality of furnace chambers (12) which are interconnected by heating ducts (17), are formed as heat exchangers and serve for receiving the anodes, in which method, to operate the heating zone, a first partial amount of the hot air formed in the cooling zone by the heat dissipated from the anodes is directed into the heating zone by means of a first suction extraction device (23) and a second partial amount of the hot air formed in the cooling zone is directed to a further heat exchanger (27), formed independently of the annular anode furnace, by means of a second suction extraction device (21), wherein the heating up of the heat transfer medium used for operating the heat exchanger takes place primarily by means of the hot air removed from the cooling zone.

Description

technical field [0001] The invention relates to a method for recovering heat in the production of anodes in an anode ring furnace comprising at least one furnace unit with a heating zone, a combustion zone and a cooling zone, each zone Each has a plurality of chambers interconnected by heating channels, these chambers are designed as heat exchangers and are used to accommodate the anodes, in this way, for the operation of the heating zone, by means of the first suction device, the cooling zone will A first part of the hot air generated by the waste heat of the anode is conveyed into the heating zone, and a second part of the hot air formed in the cooling zone is conveyed to other heat independent of the anode annular furnace by means of a second suction device. in the switch. In addition, the present invention also relates to a device for implementing the above method. Background technique [0002] This method can be used in the production of anodes required for molten ele...
