Abstract
A plant for pre-heating by fluidizing and for milling coking coal in a treatment chamber is combined, by means of heat a exchanger interposed in a circuit for recirculating heat-conveying gas, with a plant for the dry quenching of hot coke in a quenching chamber. The flow, through the heat exchanger, of recycled quenching fumes of the coke is regulated in dependence on the rate at which the coal is introduced into the treatment chamber by a screw conveyor. An auxiliary heat combustion chamber permits precise control of the temperature in the treatment chamber.
