ABSTRACT:
Apparatus and method for removing tarry deposits from the sealing surface of coke oven doors. At least the lowermost portion of the sealing surface is cleaned by reciprocating, fan-shaped, high pressure water jets, directed so as to undercut the tarry deposit. Removal of the deposits from the side portions of the sealing surface may be accomplished by the use of movable scraper blades which on encountering a hard deposit are adapted to be pressed more firmly into the deposit.
