になっている。FIG. 1 is a diagram showing a conventional coke dry fire extinguishing furnace. (1) is a cooling tower, (2) is a cooling gas, (3) is a high temperature exhaust gas, and (4) is a boiler. Red-hot coke discharged from the coke oven is charged through the coke charging port (5), cooled by cooling gas (2), and cut out from cutout D (6). On the other hand, high-temperature exhaust gas (3) discharged from the cooling tower (1) is led to a boiler (4) where steam is generated and is recycled again as cooling gas (2).
