METHOD AND DEVICE FOR CONTROLLING ADHESION OF TAR TO PLACE CLOSE TO DOOR OPENING OF CARBONIZATION CHAMBER OF COKE OVEN

摘要

PROBLEM TO BE SOLVED: To control the adhesion of carbon adhered to the periphery of a door opening portion by removing tar which is stayed on the door opening portion of a coke oven carbonization chamber as a raw material for the carbon. SOLUTION: Compressed gas-jetting nozzles 2 which can jet a compressed gas on tar stayed close to the door opening portion 3 of the carbonization chamber of a coke oven are attached to the lower portion of the support bracket 5 of a sheet surface cleaner loaded on an extruder. The jetting axes of the compressed gas-jetting nozzles 2 are obliquely downward directed to the oven bottom at the door opening portion 3. Each compressed gas-jetting nozzle 2 is connected to a compressor and a compressed gas tank through a control valve, and compressed air is forcefully charged from the compressor and the compression gas tank.
