摘要
以新兴铸管轧钢加热炉低氮燃烧超低排放改造为例,介绍了轧钢加热炉"炉内烟气循环+分级燃烧+精细调试"低氮燃烧技术及其应用实践.生产实践表明,应用该技术后,从排放源头降低NOx产生,实现了稳定满足国家和地方环保标准限值的目标,并取得良好的环保成效和经济效益,为钢铁行业超低排放提供一种可行可靠的技术参考和工艺借鉴.
Abstract
Taking the low nitrogen combustion and ultra-low emission transformation of emerging cast pipe steel rolling heating furnaces as an example,this article introduces the low nitrogen combustion technology of"furnace flue gas circulation+staged combustion+fine debugging"for steel rolling heating furnaces and application practice.The production practice shows after the technology is applied,it reduces NOx generation from the emission source,achieves the goal of stable compliance with national and local environmental protection standards,and achieves good environmental and economic benefits,providing a feasible and reliable technical reference and process reference for ultra-low emissions in the steel industry.
