<p><P>PROBLEM TO BE SOLVED: To provide a temperature rise method for a hot re-laid oven wall of a coke oven by which temperature of an oven wall re-laid by partial hot repair of a coke oven can be easily and uniformly risen without using a large number of man-hour and a special heating means, and as a result, joint loss and crack generation in the bricks of the repaired part is prevented. <P>SOLUTION: After hot re-laying of bricks of flues 21a, 21b in a chamber coke oven has been performed and until the temperature rise of the re-laid bricks is completed, the temperature rise of the re-laid bricks is performed by: making apertures 35 in a part of lower portions of the oven wall bricks of the flues 21a, 21b subjected to the brick re-laying and closing flue ports 22, 23 which are fuel gas or air supply openings of the flues 21a, 21b; introducing hot air 41 from a back non-re-laid part, which is caused to flow into a carbonization chamber 10a adjacent to the flues 21a, 21b, into the flues 21a, 21b through the apertures 35; and discharging the hot air 41 rising within the flues 21a, 21b, from flue inspection holes 30 disposed just above the flues 21a, 21b. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
