TUBE DEVICE FOR EXTRACTION OF THE GAS EVOLVED IN THE CHARGING OF COKE OVENS

摘要

A b s t r a c t The invention relates to a device for inhibiting the egress of gases evolved in the charging of coke oven chambers. The device is a tube device which is placed before the levelling opening in the door of the chamber to be charged and connected to the levelling opening of an adjacent oven, in order that the gases evolved in charging may be removed to the adjacent chamber where carbonization is in an advanced state. The tube device comprises: the two tubular front parts engageable with the levelling openings; a U-shaped connecting member; and a tubular rear part which is disposed in registration with the path of the leveller and through which the same can extend and which is closable by a flap raisable by the leveller. The tube device is mounted on a truck movable in the direction of the oven chamber axis on a track disposed on the leveller frame.
