摘要
结合我国钢铁工业CO2排放现状,概述了增加废钢电炉工艺粗钢产量、采用高质量铁料、改善能源结构、采用低碳炼钢技术、加强生产设备大型化和应用节能技术等CO2减排措施.我国钢铁行业目前的主要节能技术有干熄焦、煤调湿、煤气回收利用、余热余能回收利用及低压饱和蒸汽发电等.通过各种节能技术的应用,2020年CO2排放量可降低2.9亿t.根据减排措施的可操作性和实现阶段,从短期和长期两方面对我国钢铁工业CO2减排进行了展望.
Measures of CO2 reduction are analyzed with actuality of CO2 emission from iron and steel making in China, such as, increasing the production of steel scrap-EAF process, improving the quality of iron, improving the ratio of non-fossil energy, employing low carbon technologies, enlarging scale of equipment and using energy-efficient technologies. There are many technologies of energy conservation and emission reduction in iron and steel industry such as coke dry quenching, coal moisture control, gas recycling, waste heat and energy recycling and low pressure saturated steam power technology. CO2 emission will reduce 290 million tons through the application of energy-saving technologies. In short-term and long-term aspects, the prospect of CO2 reduction in domestic iron and steel industry is analyzed.
