DOOR FOR COKE OVEN AND METHOD OF OPERATING IT

摘要

A coke-oven door for use in combination with a coke-oven chamber having an upright doorjamb has a door panel whose periphery is complementary to the doorjamb and which is provided with a seal extending around that periphery between the same and the doorjamb. A plug with a heat-insulating outer wall is carried on this panel within the seal and projects through the doorjamb into the chamber. This plug is formed with a vertically extending and upwardly open passage bounded by a metallic inner wall having gaps by which gases produced during coking adjacent the plug enter the passage on their way to a flue, exchanging heat through the metallic wall with the charge in the oven and thereby aiding the coking operation.
