本文就干燥作业的能源利用与节约的通性问题作了分析与研究,认为干燥作业有很大的节能潜力,并指出,只要认真抓好炉灶改革和余热回收利用,同时采用合理的干燥工艺和干燥介质,使能耗降低40～50％是可以实现的。此外,文中对能源结构也作了简要的讨论。 This paper analyzes and studies the general problems of energy utilization and saving in the drying operation, and considers that the drying operation has great potential for energy saving. He pointed out that as long as the stove reform and the waste heat recovery and utilization are conscientiously carried out, at the same time, a reasonable drying process and Drying medium, the energy consumption to reduce 40 ~ 50% can be achieved. In addition, the article also made a brief discussion of energy structure.
