Regeneratively-operated coke oven

摘要

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.
