钢铁企业低温热能的回收利用 ·1 · 钢铁企业低温热能的回收利用 墙新奇 （宝钢集团新疆八钢有限公司，乌鲁木齐 830022 ） 摘 要 钢铁企业的低温热能种类较多，总量很大，并具有再生性，但这部分热能回收利用的很少，存在节能的机 会和潜力。本文对钢铁企业的低温热能按其载体的不同，分为热水低温热能和废气低温热能，对钢铁企业各工序低 温热能存在的主要形式进行了统计，对目前钢铁企业低温热能利用的技术和用途进行了论述。本文重点介绍了冷电 循环技术的工作原理，并对冷电循环利用低温热能的机理进行了研究，以钢铁企业的热水低温热能的回收利用为例 对冷电循环的应用前景进行了展示，从而进一步揭示钢铁企业低温热能的潜力，以引起对低温热能回收利用的关注。 关键词 钢铁企业，低温热能，冷电循环1 Low Temperature Thermal Energy Recycling of the Iron and Steel Enterprises Qiang Xinqi (Baosteel Group Xinjiang Baiyi Iron Steel Co., Ltd., Urumqi 830022, China) Abstract Iron and steel enterprises of low temperature thermal energy sort is more, total amount is large, and have a reproducible, but this part of the thermal energy recycling rarely， exist opportunities and potential of energy saving. In this paper, the irzon and steel enterprises of low temperature thermal energy carrier according to the different, divided into hot water low temperature thermal energy and waste gas low temperature thermal energy. The main form of existing in the process of low temperature thermal energy for statistics. The current technology of low temperature thermal energy utilization in iron and steel enterprises and uses are discussed. This paper mainly introduces the working principle of the cold electricity circulation technology. Cold electricity circulation mechanism of low temperature heat were studied.In iron and steel enterprises of low temperature hot water thermal energy recycling, for example on the cold electricity circulation applications, to further reveal the potential of low temperature heat energy,
