Abstract

PURPOSE: To enhance the waste heat recovering efficiency of a cooler in the next process by reductively regulating the volume of waste gas sucked in a wind box and the following wind boxes at the point of time when the sintering zone of a sintering machine reaches the upper surface of the grate.
CONSTITUTION: Sintered ore sintered with a sintering machine 1 is crushed with a crusher 2, fed to a cooler 3, and cooled. At this time, by reductively regulating the volume of waste gas sucked in a wind box (W.B.) No.14 and the following wind boxes at the point of time when the sintering zone of the machine 1 reaches the upper surface of the grate, the cooling degree is reduced, and the one is discharged to the cooler 3 at a higher temp. such as 500W540°C. At the same time, by adjusting the temp. of waste gas at the inlet of a dust collector for sintering to 100W110°C, the dust collecting and desulfurizing effects of waste gas are enhanced, the temp. of waste gas for W.B. 14 from the cooler 3 is raised, and the heat recovering efficiency of a boiler 23 is also enhanced.
