Review of Waste Heat Utilization Technologies for Industry Processes

概述了余热利用的热交换技术、余热制冷制热技术、低温有机朗肯循环及Kaliana循环余热发电技术的应用,并对其热力学原理以及研究方法进行了分析。认为研究推广低温有机朗肯循环及Kalina循环等低温余热发电技术对提高余热利用率更加有效,余热制冷制热技术的应用必须与工艺过程相结合,加强计算机模拟在制冷过程的设计中的应用。

This paper reviewed the characteristics and applications of waste heat recovery technologies such as heat transfer utilization, refrigeration and heat pump. power generation by organic Rankine cycle （ORC） system and Kalina cycle. The thermodynamic principle and research method existing in the recovery of waste heats were carried out. The dissemination of ORC system and Kalina cycle system are necessary for increasing the effective of waste heat utilization. Meanwhile. refrigeration and heat pump technologies should be combined with specific industry process, application of simulation to the design also should be enhanced.
