The prepared coal is charged into carbonization chambers by a larry car. The coals in the carbonization chamber are carbonized by heat transferred from the combustion chamber. When the coking process is completed, the oven doors are opened, the pusher is spotted opposite the pusherside door, and the hot coke is forced out of the oven by means of
