The coking oven has a vertical rectangular chamber with lateral heating walls to which heat exchangers are attached. The roof from the face of the chamber is a hermetic chute, whose vertical walls are connected to the lateral walls of the chamber and which has the feed conveyor with an unloading and evening device; to the upper wall of which a hermetic loading funnel for coal is attached and a lead-off for gas. The bottom of the chamber consists of segmented locks that are taken up by the hermetic chute. The chute's vertical walls are connected to the vertical walls of the chamber and its horizontal wall has a hermetic unloading funnel with a conveyor for coke removal. Height and width of the chamber are similar to standard chambers; their length reaches 100 to 200 m and longer. Length depends on coke preparation time and speed with which the unloading device can transfer coal. For normal operation, the conveyor belt must function properly in conjunction with the unloading device and segmented locks that form the bottom of the chamber.
