工业过程的特征在于能量损失，例如在不同温度水平下以废气或废水的形式排放到环境中的热流。因此，废热回收（WHR）一直是行业面临的挑战，因为它可以节省能源，提高能源效率和可持续性。因此，WHR方法和技术已在欧盟（以及全世界）广泛使用。本文回顾和回顾了传统的WHR技术，它们在所有类型的行业中的应用及其局限性。特别注意的是替代“新”技术，这是讨论的参数，如预计能源和成本节约。最后，对有关WHR技术应用的案例研究进行了扩展回顾。这里提供的信息也可用于确定目标能源性能，以及资本和安装成本，以增加WHR技术的吸引力，从而获得行业的广泛采用。
Industrial processes are characterized by energy losses, such as heat streams rejected to the environment in the form of exhaust gases or effluents occurring at different temperature levels. Hence, waste heat recovery (WHR) has been a challenge for industries, as it can lead to energy savings, higher energy efficiency, and sustainability. As a consequence, WHR methods and technologies have been used extensively in the European Union (EU) (and worldwide for that matter). The current paper revisits and reviews conventional WHR technologies, their use in all types of industry, and their limitations. Special attention is given to alternative "new" technologies, which are discussed for parameters such as projected energy and cost savings. Finally, an extended review of case studies regarding applications of WHR technologies is presented. The information presented here can also be used to determine target energy performance, as well as capital and installation costs, for increasing the attractiveness of WHR technologies, leading to the widespread adoption by industry.
