中国钢铁工业节能减排潜力及能效提升途径

 钢铁工业是典型的资源能源密集型行业，是节能减排重点行业之一。总结了中国钢铁工业“十二五”以来所取得的节能减排进展及存在的问题，采用动态物质流分析方法，构建了钢需求量和废钢回收量预测模型，基于35项重点节能减排技术评估，结合能源消耗与CO2排放模型，分析了中国钢铁工业到2050年的节能减排潜力并分析了各因素的影响。在此基础上提出了提升中国钢铁工业能效的若干途径，为钢铁工业的绿色低碳转型、可持续发展提供理论指导。

Potential of energy saving and emission reduction and energy efficiency improvement of China's steel industry

The iron and steel industry is a typical resource- and energy-intensive industry and one of key industries for the energy conservation and emission reduction. The progress and problems in the energy conservation and emission reduction achieved by China's iron and steel industries since the 12th Five-Year Plan were summarized. Based on the dynamic material flow analysis method， the steel demand forecast and the scrap recovery model were constructed. Based on the evaluation of 35 energy saving and emission reduction technologies， combined with the energy consumption and CO2 emission models， the energy saving potential of the China's iron and steel industry by 2050 and the impact of various factors were analyzed. Finally， several ways to improve the energy efficiency were proposed which provides the theoretical guidance for the green and low-carbon transformation and sustainable development of the China's iron and steel industry.
