Abstract
The system according to the invention for thermally processing lumpy solid material substantially comprises a preheating device, a furnace and a separation or classification device which is arranged therebetween and which has a coarse material outlet connected to the furnace and a fine material outlet. The furnace and the preheating device are connected to each other by means of a gas/solid material line which is arranged so as to be inclined relative to the vertical, the furnace exhaust gases being introduced at the end of the gas/solid material line at the furnace side and the preheated solid material being supplied at the end at the preheater side. The separation or classification device is connected to a bypass line which branches off from the gas/solid material line so that at least a partial amount of the preheated solid material can be branched off via the bypass line by means of gravitational force and can be supplied to the separation or classification device.
