摘要
节能减排主要依靠工业领域,工业余热利用是重要内容。本文从余热利用过程能量转换情况角度,概述了国内用于余热利用的热交换技术、热功转换余热发电技术及余热制冷制热技术及其设备的技术特点及应用概况,分析了工业余热利用中的存在的问题,认为需进一步推广余热锅炉及低温汽轮机余热发电技术,提高中高温余热的利用率,需要强化研究并掌握有机朗肯循环等300℃以下低温余热发电技术,积极向工程应用推广,提高低品位余热利用率。
Waste heat recovery in industry is indispensable in saving energy, lowering energy consumption and reducing pollutants. This paper overviewed the characteristics and applications of waste heat recovery technologies in China such as heat transfer utilization, power generation technologies, refrigeration and heat pump. The dissemination of waste heat boiler and power generation technologies is necessary for increasing the ratio of midium/high temperature waste heat utilization; meanwhile Organic Rankine Cycle system is an effective solution to the low temperature waste heat recovery and the development is a pressing need.
