Abstract

The present invention is provided with: a first processing device main body ( 111 ) that processes carbonized coal ( 1 ) by means of processing gas ( 103 ) of which the oxygen concentration has been adjusted by blowers ( 113,115 ); a second processing device main body ( 121 ) that processes primary processed carbonized coal ( 2 a ), which results from being processed at the first processing device main body, by means of air ( 102 ) fed by a blower ( 122 ); a second-processing-gas state detection means that detects the state of the air used within the second processing device main body; and a control device ( 130 ) that, on the basis of information from the second-processing—gas state detection means, controls the blowers ( 113,115 ) in a manner so as to adjust the oxygen concentration in the processing gas when the state of the air has diverged from a predetermined state.
