APPARATUS FOR CLEANING THE DOORS OF COKING OVENS

摘要

An apparatus for cleaning coking oven doors having a sealing edge for placing on the door frame. The doors are adapted to be driven to be placed in front of the apparatus which is provided with nozzles for discharging pressurized water on the door regions which are situated close to the sealing edge and are covered with encrusted deposits. The apparatus is characterized in that a pair of nozzles, which is situated on both sides of the inward-driven door is aimed at the gap between the sealing edge and a door plug. The nozzles are connected to a pressurized water supply duct and are placed at a distance from each other equivalent to approximately half the door height. The nozzles are disposed in a vertically adjustable frame so that the top and bottom angle subtended by the sealing edge can be subjected to pressurized water, namely by the top nozzles in the top position and by the bottom nozzles in the bottom position. The top nozzles are pivotable in the top limiting position and the bottom nozzles are pivotable in the bottom limiting position so as to bias the regions of the door situated at the top and at the bottom horizontal portion of the sealing edge. The nozzles are disposed on horizontal inwardly pivotable tubes which are situated on both sides of the plug of the inward-driven door and are connected to the supply duct for pressurized water.
