Abstract
Thin-walled corundum tubes form smooth and pore-free surfaces for supplying non-preheated gas to the burners in heating flues between coking chambers of a coke oven. Silica blocks forming a burner in the heating flues have an enlarged opening to receive the tube so that the tube projects a short distance from the top of the burner and extends therealong below the floor of the heating flue. The tube is made of corundum or similar refractory material to prevent the accretion of carbon which precipitates at a high temperature from the rich gas.
Claims8
Apparatus for supplying non-preheated gas to heating flues between oven chambers of a regeneratively-heated coke oven, said apparatus including burners projecting into said heating flues, said burners having a lining forming a gas-conducting wall surface consisting of a refractory material capable of withstanding temperatures of at least 1000.degree. C. and defining a smoothness sufficient to substantially prevent accretion of carbon on said wall surface at said temperatures.
