The bricks in the carbonization chamber are heated from the combustion chamber to 1000 ° C
After being used for a long time, wear, cracks, etc. due to rapid cooling from the high temperature of 1200 ° C by charging coal, abrasion due to extrusion of dry-distilled coke, and repeated carbon adhesion and peeling that occur during carbonization Get damaged. In such a damaged carbonization chamber, coke cannot be pushed out and normal coal dry distillation cannot be performed, so repair such as transshipment of wall bricks is required.

冷却しなければならない。When repairing a damaged portion of the carbonization chamber wall, it is necessary to maintain a high temperature state on the side wall of the combustion chamber where the repair is not performed in order to prevent cracking due to temperature decrease. Further, since the brick repair work is performed in a high-temperature carbonization chamber, it is necessary to cool the repair part as much as possible in order to protect the worker from the high temperature and facilitate the work.

内に取り入れ、その雰囲気温度を調節するものである。Japanese Unexamined Patent Publication No. 6-41538 discloses a method for performing hot repair in a carbonization chamber. This means that a vertical duct is provided downward at one end of a ceiling duct having a predetermined length in the horizontal direction, and a plurality of air suction holes are provided on the inner surface side of the vertical duct whose suction positions can be adjusted up and down. The vertical stiffener hanging from the ceiling duct at an appropriate interval and a horizontal stiffener connecting the vertical duct and the lower end of the vertical stiffener are attached to form a rectangular frame.
It is a heat insulation panel used for hot repair work of a coke oven that spreads heat insulation material on the front of its rectangular frame. This heat insulation box is hung inside the work compartment, and vertical ducts and ceilings with air suction holes are installed. The flow of outside air is taken into the working compartment through the duct to control the ambient temperature.
