<p>PROBLEM TO BE SOLVED: To provide a cooling apparatus cooling sintered ores and pellets having high ability to recover exhaust heat, and an exhaust control method in the cooling apparatus.SOLUTION: A cooling apparatus 1 cooling sintered ores P and pellets of the present invention is arranged in a production line producing the sintered ores P and the pellets and cools the sintered ores P after being sintered and the pellets, the cooling apparatus 1 comprises: a forced circulation passage 3 through which the air after cooling the sintered ores P and the pellets is recovered and the recovered air is returned as a cooling source for the sintered ores P and the pellets; a heat exchanger 7 provided on the forced circulation passage 3 and for recovering heat from the air circulating through the forced circulation passage 3; and a circulation blower 8 provided on the forced circulation passage 3 and for circulating the air of the forced circulation passage 3. In the cooling apparatus 1, the forced circulation passage 3 is provided with discharge means 12 for discharging the air after heat exchange in the heat exchanger 7 to the outside of the forced circulation passage 3.</p> |
