<p>A coke dry quenching facility (100) includes a cooling tower (1) including a charge port (11) for charging the red-hot coke on an upper side and configured to cool the red-hot coke charged therein; a furnace top lid (12) configured to open and close the charge port (11); a gas circulation passage (31, 22) configured for gas including cooling gas to be circulated and including a cooling gas flow passage (31) through which the cooling gas flows toward the cooling tower (1) and a high temperature gas flow passage (22) through which high temperature gas generated by heat exchange with the red-hot coke flows; a waste heat recovery boiler (4) disposed in the gas circulation passage (31, 22) and configured to recover heat of the cooling gas having a high temperature due to heat exchange with the red-hot coke; an adjustment mechanism (5, 6) configured to adjust a flow rate of gas circulated through the cooling tower (1) and the gas circulation passage (31, 22); and a control system (7) that controls the flow rate of the gas circulated through the cooling tower (1) and the gas circulation passage (31, 22) to be smaller during a charging operation of the red-hot coke into the cooling tower (1) with the furnace top lid (12) set open, as compared to a normal running operation with the furnace top lid (12) set closed.</p> |
