抄録

The carbon deposition mechanism in the free space of coke oven chambers has been studied under Coal Moisture Control (CMC) operation by the actual oven measurements. It was found that the amount of carbon deposits in CMC operation increases as much as 45 to 75 mass% compared with those in wet coal operation. The carryover fines are not negligible mass for the carbon deposits, namely, the carbon deposits on the base portion of an ascension pipe in CMC operation contained about 20 mass% of materials derived from carryover fines, and the majority of the deposits at the initial stage of the carbonization were derived from the carryover fines. The influence of volatile matter on the carbon deposits in CMC operation was greater than that in wet coal operation.
