A coke oven door prevents the generation of poor-quality coke and yielding and adhesion of tar by promoting the temperature rise of coal particles charged near the coke oven door of a coke oven . The coke oven door comprises a heat-insulating box provided on the coke oven side of a oven door structure adapted to open and close an opening in the coke oven in which the coal particles are charged, horizontal support frames fitted in said heat-insulating box to vertically partition the heat-insulating box into multiple sections, and a bottom-less gas migration and isolation hollow plug formed by laterally and vertically putting together removable shield bars in spaces between said horizontal support frames with small ventilating spaces left on both sides thereof.
A coke oven door to promote temperature rise in the vicinity thereof which comprises a heat-insulating box provided on the inner side of an oven door structure adapted to open and close a door jamb in the coke oven charged with coal particles via a seal plate pressed against said door jamb, horizontal support frames provided to partition the height of said heat-insulating box into multiple sections, and a bottom-less gas migration and isolation chamber formed by arranging shield bars to prevent the entry of coal particles , laterally and vertically with small ventilating spaces left on both sides thereof, to fill the spaces between said horizontal support frames, with the upper end thereof pivotally fastened to said horizontal support frames.
A coke oven door to promote temperature rise in the vicinity thereof which comprises a heat-insulating box provided on the inner side of an oven door structure adapted to open and close a door jamb in the coke oven charged with coal particles via a seal plate pressed against said door jamb, upper shield bars fitted in spaces in said heat-insulating box partitioned by horizontal support frames having a slot extending in the direction of oven height and provided in the mating surface of the lower end thereof, lower shield bars having a downward-extending projection adapted to pass through and engaging with said slot and a projecting stopper adapted to come in contact with the lower end of said horizontal support frame provided in the lower end thereof.
A coke oven door to promote temperature rise in the vicinity thereof which comprises a heat-insulating box provided on the inner side of an oven door structure adapted to open and close a door jamb in the coke oven charged with coal particles via a seal plate pressed against said door jamb, horizontal support frames having a rugged engaging portion at the upper edge and provided to partition the height of said heat-insulating box into multiple sections, and a bottom-less gas migration and isolation hollow plug formed by putting together, both vertically and laterally, shield bars having two separated hooks adapted to engage with the dents on both sides of a projection on said horizontal support frame by stepped joints, with small ventilating spaces provided on both sides thereof and vertical sliding spaces on the projecting side of both stepped joints, and a projecting stopper to prevent the breakoff of the shield bar by coming into contact with said horizontal support frame provided in the lower part of the shield bar.
