工业余热的回收利用研究--以鲁邦大河热电厂为例

Research on Recovery and Utilization of Industrial Remaining Heat--Taking Lubang Dahe Thermal Power Plant as an Example

随着我国经济的迅速发展,能源的消耗量日益增加。提高能源利用效率是当前工业生产发展一个很重要的课题,这不仅关系到工业的发展,更关系到整个国家的未来。近年,全球能源危机日益严重,能源紧缺困扰全球经济发展。如何降低单位产品的能源消耗,成为各国研究的一个很重要的课题。文章通过对鲁邦大河热电厂的余热利用方式以及节能效果的调研,研究了该热电厂整个生产工艺流程,简单阐述了发电厂烟气余热利用背景,分析了该发电厂烟气余热利用与应用技术方案,重点介绍了热管在余热利用中所采用的方式及方法,以及经济投入。并对火该厂烟气余热利用与应用效益进行了进一步探讨,发现了余热产生的原因,介绍了余热的产生及其利用模式。结果表明回收利用余热将会节约大量的能量,减少污染物的排放,实现节能减排。

With the rapid development of Chinese economy,energy consumption is increasing day by day.Improving energy efficiency is a very important issue in the development of industrial production,which is not only related to the development of industry,but also related to the future of the whole country.In recent years,the global energy crisis is becoming more and more serious,and the energy shortage has troubled the global economic development.How to reduce the energy consumption per unit product has become a very important research topic.Based on the investigation of waste heat utilization mode and energy saving effect of Lubang Dahe thermal power plant,this paper studies the whole production process of the thermal power plant,briefly describes the background of flue gas waste heat utilization in power plant,analyzes the technical scheme of flue gas waste heat utilization and application in the power plant,and emphatically introduces the methods and methods of heat pipe in waste heat utilization and economic investment.The utilization of flue gas waste heat and its application benefit are further discussed.The causes of waste heat generation are found,and the generation and utilization mode of waste heat are introduced.The results show that waste heat recovery will save a lot of energy,reduce the emission of pollutants,and achieve energy saving and emission reduction.
