Abstract
Addressing the issues of high energy consumption and high carbon emissions in the sintering process of the iron and steel industry,this paper systematically analyzes the basic prin-ciples,key control points,and practical energy-saving and carbon-reduction effects of four tech-nologies:oxygen-enriched ignition operation,deep-bed sintering process,sintering flue gas recir-culation,and circular cooler system optimization.Production practice on a 500 m2 sintering machine at an iron and steel enterprise demonstrates that the comprehensive application of the above tech-nologies can reduce solid fuel consumption by 12.9%,decrease process energy consumption by 15.6%,increase waste heat power generation by 39.0%,and achieve an annual reduction of CO2 emissions by 113 000 tons,which provides a reliable technical pathway for achieving green and low-carbon production in the sintering process.关键词
