COAL DEACTIVATION PROCESSING DEVICE

摘要

Provided is a coal deactivation processing device that can easily obtain modified coal that has been adjusted to an appropriate level of deactivation. 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.
