RAW COAL CHARGING DEVICE TO COKE OVEN, AND CHARGING METHOD THEREFOR

PROBLEM TO BE SOLVED: To provide a raw coal charging device to a coke oven and a charging method therefor capable of producing coke at a low cost without deteriorating the quality of the coke even if the blending ratio of non or slightly caking coal is increased.SOLUTION: In the raw coal charging device, a screw feed 13 is arranged directly below a hopper 12 mounted at a larry car running at the oven top part of a coke oven, and raw coal C in the hopper 12 is cut with the screw feeder 13 and is charged to the carbonization chamber of the coke oven. The device comprises: a coking anaplerotic material tank mounted at the larry car and storing a coking anaplerotic material M; and a nozzle 23 installed at the lower part in the hopper 12 and jetting the coking anaplerotic material M fed from the coking anaplerotic material tank to the lower part.
