Abstract

In the European Union (EU), industrial sectors use 26% of the primary energy consumption and are characterized by large amounts of energy losses in the form of waste heat at different temperature levels. Their recovery is a challenge but also an opportunity for science and business. In this study, after a brief description of the conventional Waste Heat Recovery (WHR) approaches, the novel technologies under development within the I-ThERM Horizon 2020 project are presented and assessed from an energy and market perspectives. These technologies are: heat to power conversion systems based on bottoming thermodynamic cycles (Trilateral Flash Cycle for low grade waste heat and Joule-Brayton cycle working with supercritical carbon dioxide for high temperature waste heat sources); heat recovery devices based on heat pipes (flat heat pipe for high grade radiative heat sources and condensing economizer for acidic effluents).

欧盟工业废热回收及提出的新技术

在欧盟(EU)，工业部门使用了26%的一次能源消耗，其特点是在不同温度水平下以废热的形式大量损失能源。它们的复苏对科学和商业来说是一个挑战，但也是一个机遇。在本研究中，在简要介绍了传统的废热回收(WHR)方法之后，从能源和市场的角度介绍了I-ThERM Horizon 2020项目中正在开发的新技术。这些技术是:基于底部热力学循环的热电转换系统(用于低品位废热的三边闪蒸循环和用于高温废热源的超临界二氧化碳焦耳-布雷顿循环);基于热管的热回收装置(高档辐射热源用平板热管，酸性废水用冷凝省煤器)。
