摘　　要：在全工业废渣水泥生产线,采用低温煅烧技术,低温、长火焰煅烧法,加大三次风管,减少一、二次风的用量,加大三次风的用量,以及保持回转窑高快转率等技术措施,在不使用任何还原剂的前提下,能够减少窑内高温区氮气与氧气的化合,生成NO_x的量,实现减少窑尾烟气中温室气体NO_x排放量,达到烟气中NO_x<400mg/m^3,满足水泥生产中窑尾烟气中NO_x达标排放的要求,防止二次污染,降低生产成本,实现绿色生产的目的。In the cement production line of industrial waste, using low temperature calcination technology, low temperature and long flame calcination method, increase three times the wind pipe, reduce one or two times the amount of wind, increasing three times the amount of wind, and keep the high speed rotary kiln conversion rate and other technical measures, without the use of any agent under the premise to reduce the high temperature area, nitrogen and oxygen in the kiln is combined, the amount of NOx generated, to achieve reduction of greenhouse gas emissions in NOx kiln flue gas, flue gas reached NOx〈400mg/m3, meet in the production of cement kiln flue gas NOx emission requirements, to prevent two pollution, reduce production costs, achieve the objective of green production.
