摘　　要：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。The adaption of air regenerative burner or air-fuel regenerative burner is analyzed for different fuels. Two kinds of special regenerative burner have been developed for the two kinds of combustion which is used in large magnesium reduction furnace. It is shown that this design is helpful to achieve high-temperature low-oxidation burning, enhance the effective of energy sources, improve the uniform temperature field in the furnace chamber, shorten pollution and elongate the lifetime of the reduction jars.
