ABSTRACT:
A device for producing abrasion-proof coke forms from bituminous or brown coal briquettes, charcoal or peat, comprising, a preheating stage, a dehydrating stage, a carbonization stage and a cooling stage, each stacked in a column to form a tower furnace. Each of the stages include an annular zone for receiving the coal or charcoal material and each stage is supplied with a separate and independent gas circuit. Each annular zone is formed between an inner substantially cylindrical jacket and an outer substantially cylindrical jacket with a shaft space defined in the inner cylindrical jacket. Heaters for the gas circuits of the preheating, dehydrating and carbonizing stages are disposed in the shaft space.
