Summary:PURPOSE:To recover effectively the potential heat of the return part of the grate of a Dwight-Lloyd type sintering apparatus by utilizing hot air obtd. by recovering the potential heat as air for calcination. CONSTITUTION:A suction hood 15 is placed above the return part of the grate 3 of a sintering apparatus, and the open air is sucked upward through the grate 3 to transfer the potential heat of the grate 3 to the air. Hot air recovered by the heat transfer is sent to a hood 17 and mixed with exhaust gas after dust collection from the ore discharging section of the sintering apparatus. The gaseous mixture is utilized as air for calcination at the ore discharging side of the sintering apparatus. By this method the potential heat is effectively recovered.
