分析单预热和双预热燃烧方式适用不同燃料的情况,同时针对两种燃烧方式,分别开发了适用于大型金属镁还原炉的蓄热燃烧器。实践表明,该燃烧器能较好地实现高温低氧燃烧,提高能源利用率和炉温均匀性,减少污染物的排放,延长还原罐的使用寿命,在实际应用中取得了良好的效果。 Analysis of single preheating and dual preheating combustion for different fuels, and for the two kinds of combustion mode, respectively, for the development of a large magnesium reduction furnace regenerative burner. Practice shows that the burner can achieve high temperature and low oxygen combustion, improve energy efficiency and uniformity of furnace temperature, reduce pollutant emissions and extend the service life of the reduction tank. The practical application has achieved good results.
