中国钢铁工业CO2减排的进步与展望

CO₂减排已引起中国钢铁行业的高度重视。中国钢铁行业20多年来，一直重视节能工作，并取得了巨大成就，成为CO₂减排最重要的基础。1990年以来，不同时间段的吨钢综合能耗年均降低值为3.02～5.85个百分点，主要大型钢铁企业能耗水平已与国外先进企业相当，干法除尘、冶金煤气、余压、余热利用技术水平不断提高，钢铁能耗统计不断完善，先进的“少碳”、“非涉碳”冶金技术正在研发。在保证中国发展的前提下，不断淘汰落后企业和装备，深化节能技术，进一步降低CO₂是中国钢铁工业最为迫切和长远的任务。

Improvement and Development of Decreasing CO2 Emission in China Iron and Steel Enterprises

The Chinese steel industry has paid more attention to minimize CO2 emission. In the past two decades, China attached great importance to energy saving and made great achievements on it which lead to the decrease of CO2 emission. Since 1990, the energy consumption per ton crude steel has decreased by（3.02%-5.85%） per year in average. The energy consumption of the main large scale steel enterprises in China is at the same level as the advanced steel enterprises in foreign countries at present. The technologies of dedusting without water, utilization of the byproduct gases, wasted pressure and heat have been improving. The statistics of energy consumption is also improving. Advanced technologies, such as ＂low-carbon metallurgy＂ and ＂non-carbon metallurgy＂, have been developed or under going. In order to ensure the development of our country, it becomes a long-term and urgent task to reduce CO2 emission by eliminating the enterprises and equipments which is not suitable for the development of our steel industry and further development of energy saving technologies.
