| 摘要 |
The invention relates to an apparatus and method for processing sludge. The apparatus comprises a processing drum (DR) provided with an inlet (IN) and an outlet (OUT) for sludge to be processed and for heat-accumulating material (HCM) in the form of particles that maintain a heat storing capacity of the sludge (SL). According to the invention, a return line (RL) for recirculating heat-accumulating material (HCM) to be removed from a sludge handling space (SHS) inside the processing drum (DR) back into the sludge handling space inside the processing drum (DR) for reuse is a return channel (RL) provided in connection with said processing drum (DR). |
