Abstract

The invention relates to a procedure for continuous supply of heat into electrically conductive bulk goods by exploiting the electrical resistance thereof in an oven chamber with an inlet opening and a drawing-off apparatus for continuous throughput of bulk goods, wherein during the throughput of material, electrical energy in the material is conducted, and to an apparatus for continuous supply of heat into electrically conductive bulk goods by exploitation of the electrical resistance thereof, in an oven chamber (1) with an inlet opening (15) and a continuous drawing-off apparatus (9) for the bulk goods, and with at least one pair of electrodes (14, 16, 19) arranged one above the other, via which the electrical energy in the material is conducted during the continuous throughput of material. Provision of an apparatus in which heat can continuously be supplied in an efficient manner to electrically conductive bulk goods by exploitation of the electrical resistance thereof during continuous throughput of material is proposed according to the invention in that having regard to the procedure, the material is conducted substantially parallel to the direction of current, between the pos…
