摘　　要：烧结矿余热竖罐式回收是研究团队提出的一项具有自主知识产权的工艺技术,其吨矿余热发电量有望达到30~35k Wh。文章在理论和实验研究的基础上,采用解析计算的方法建立了年处理量5.5万t烧结矿小型竖罐料层内气固换热解析模型,以出口冷却空气携焓?作为评价指标,得出了小试系统适宜的结构和操作参数。Vertical tank recovery of waste heat from sinter is a kind of technology put forward by our researeh team with independent iutelleetual property rights. The power generation derived from waste heat per ton of siuter ean reaeh 30 - 35 kwh. Aeeording to the theoretieal and experimental rese ar- ehes, the heat transfer model between gas and solid of the annual handling eapaeity of 55 thousand tons ＂vertieal tank was established with analytieal ealeulation method. The suitable struetural and operating parameters of vertieal tank were determined eonsidering the exergy enthalpy.
