工艺流程中低温余热回收利用技术研究

Research on Applications of Waste Heat

随着经济的发展,能源需求紧张的问题日益突出,节约能源、降低能耗愈显重要。针对当前低温余热回收利用率较低,开发低温余热回收技术,拓展低温余热的领域是当前节能减排工作中亟待解决的问题。本文主要介绍余热的分类及回收利用过程中存在的难点,并通过实例介绍低温余热应用的实例,提出余热利用中应遵循的原则,以提高余热的利用效率。

With economic development and energy shortage,save energy and reduce energy consumption become more important. With the low utilization of waste heat especially low-temperature waste heat,development low-temperature waste heat recovery technology and expand the field of low temperature waste heat are eager to be solved .This paper introduce the classification and the difficulties of using waste heat, then introduce examples of low temperature waste heat applications,and propose the principles of using waste heat in order to improve the efficient use of waste heat.
