ABSTRACT:
A furnace product is permitted to flow out by gravity from the opening defined between the lower end of a furnace wall and a furnace bottom and to accumulate on the circumferential portion of the furnace bottom with a reposing angle inherent to the product, with the accumulation being drawn out of the furnace from the circumferential portion of the furnace bottom. The furnace bottom is formed with a diameter larger than the inside diameter of the lower end of the furnace wall and vertically spaced from the lower end of the furnace so as to provide an opening therebetween through which the furnace product is allowed to pass a discharging device comprising a reciprocating raking arm with its end movable across the circumferential portion of the furnace bottom operates to remove product therefrom.
