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 (2a), 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.
