Apparatus for cleaning coke oven doors

摘要

Apparatus for cleaning incrusted deposits from the regions of coke oven doors between a central refractory sealing plug and a surrounding sealing edge or strip with the use of two pairs of nozzles carried on the upper and lower ends of a frame which can traverse the inner end of the door on which the sealing plug is carried. The frame has a length preferably one-half the height of the door such that the upper nozzles will clean the upper half of the door while the lower nozzles clean the lower half. The nozzles are pivotally carried on the frame such that they can be actuated to clean the horizontally-extending portions of the door between the sealing plug and the sealing strip at the upper and lower extremities of the door.
