摘要：

为在烤烟烘烤期间利用太阳能替代部分燃煤，以达到节能减排的目的，对现有的密集烤房进行太阳能改造，在屋顶加装太阳能加热室，吸收太阳能并加热太阳能加热室内空气，高温空气通过内循环管道与烤房的加热室、装烟室连通，提供辅助热源。太阳能循环风机由温差控制器控制。对改造的太阳能密集烤房进行烘烤效应研究,结果表明密集型烤房的太阳能改造简单易行,经济实用，节能效果明显；太阳能提供的热量可满足烟叶烘烤前期的需要，每千克干烟耗能比改造前降低20%~24%，烘烤烟叶质量与普通密集烤房所烤烟叶质量相当，社会效益与经济效益明显，在光照好的烟区具有一定的推广价值。

Abstract:

In order to achieve energy conservation and emission reduction, a combination of energy from solar and coal has been built up based on a bulk curing barn by installing a solar heat system on the top of a bulk curing barn roof which are comprised of a heat room with valve controlled by a fan, lighting and heating transformation sheet and automatic temperature monitor. This study was focused on how much effect of the solar heating system could be as a supplemental energy to curing process, It has been turned out that not only a significant energy reduction has been achieved, but this modification bulk curing barn were easily constructed and economical, the solar energy could supply all heating from the early stage of tobacco curing process. The modified solar curing barn could save 20%-24% coal consumption per kg drying leaf as the one from a bulk curing barn at achieving the equivalent leaf quality. It has shown an encouraging prospective of benefit for economy and society especially on emission reduction and worthwhile for those area with abundant solar resource to extend this technology.
