摘　　要：对烟叶烘烤过程中产生的烟气余热进行回收利用,可实现节能减排、降低成本的目的。在密集烤房上搭建烟气余热回收系统,并与未采用烟气余热回收的密集烤房进行对照试验。试验结果表明,该系统节煤效果明显,平均每千克干烟叶的耗煤量为1.015 kg,比对照烤房节省0.362 kg,节煤率达到26.29%,烘烤成本降低0.33元/kg,节本率达到19.88%。此外,该系统烤后烟叶的外观质量、等级结构以及烟叶均价与对照密集烤房相比略有提高,不影响烟叶品质。The waste heat during curing stage was recycled and re-used, which was able to achieve the purpose of emission-reduction and energy-saving, and reduce the cost of baking. The waste heat recycling system of flue gas in tobacco bulk barn was designed and a contrast experiment was carried out for the baking tobacco leaves between the improved bulk curing barn and the conventional bulk curing barn. The results showed that, the system had obvious coal-saving effect, its average coal consumption for 1 kg dry tobacco leaves was 1.015 kg, being 0.362 kg and 26.29% less than the conventional bulk curing barn, the improved bulk curing barn could save the cost by 0.33 yuan/kg, and its cost-saving rate was 19.88%. In addition, the appearance quality, grade structure and average price of flue-cured tobacco leaves were slightly improved than those of control-cured barn, especially, the quality of tobacco leaves was not affected in the bulk curing-barn.
