以两套完全相同的烧结机余热回收系统为测试平台，研究了环冷机密封对烧结余热回收系统的影响。测试结果表明，环冷机密封的改善降低了环冷机漏风率，提高烟气量、同时降低烟气温度。在环冷机鼓风量达到某一特定值时，通过改善环冷机密封反而降低了余热回收效率。这主要是因为环冷机鼓风量增加时，空气从烧结矿中带走的热量会达到一个极限值并趋于稳定，而锅炉的排烟损失始终增加，最终导致余热回收系统的回收效率降低。

Take two completely identical sintering machine waste heat recovery systems as testing platform to research the annular cooler sealing influence on sintering waste heat recovery system .The testing result shows that the annular cooler sealing improvement can reduce annular cooler air leakage rate and increase fume volume as well as reducing the fume temperature .However , when the annular cooler blast volume reach certain level , the improve-ment of annular cooler sealing will decrease the waste heat recovery efficiency .The reason is that when the annular cooler blast volume increase , the heat taken from the sinter ore by air will reach limit value and become stable , but the boiler flue gas loss will keep increasing , finally the waste heat recovery system recovery efficiency will decrease .
