DRYING AND TEMPERATURE RAISING OF DRY COKE QUENCHING EQUIPMENT IN EARLY STAGE OF OPERATION

摘要

PURPOSE:To increase the efficiency of operation, etc. in the drying and temperature raising of a newly built quenching tower, by forming a heat insulating layer consisting of sintered ore or iron ore in place of fire bricks laid on a cooling coke layer formed above a cooling gas blower. CONSTITUTION:A cooling coke layer 19 is formed to cover a cooling gas blower 12 at the bottom of a quenching tower 10 just before drying and temperature raising of a newly built coke oven and a heat insulating layer 20 consisting of sintered ore, iron ore, etc. is formed above the coke layer 19. A drying burner 17 is mounted on the heat insulatng layer 20 and air and fuel are sent in for combustion to dry and raise the temperature of the quenching tower 10. Then the drying burner 17 is removed and red-hot coke is charged into it through an inlet 11 while a cooling gas is blown into the tower from the cooling gas blower 12 to continue temperature raising, and the cooling coke layer 19 and the heat insulating layer 20 are taken out of the quenching tower.
