Claim 1
Independent Claim
139 words
In combination, a coke oven having a chamber for coking coal and generating coke oven gases and a coke oven door sealing arrangement, said coke oven chamber having a coke oven door at one end thereof and heating flues at both sides thereof, said door coacting with a door jamb mounted cooperatively with an end brick structure of said heating flues at the ends thereof adjacent to said door, said coke oven door sealing arrangement comprising, a. a U-shaped sealing strip carried by said door that cooperates with a sealing surface of said door jamb and forms a fluid channel around said door; b. means dividing said channel into separate fluid channelways; and c. means fluidly communicating each one of said channelways with a respective end flue, whereby coke oven gases in said channelways flow into said end flues.
