摘　　要：针对传统颜式燃料器压缩空气雾化柴油燃烧效率低、污染物排放高的缺陷,将多氧燃烧技术应用于转动分银炉火法冶炼银精矿的生产实践,改造后柴油单耗和烟气CO_(2)排放均减少50%,辅料硝酸钠单耗降低约30 kg;加强了氧化精炼阶段除杂能力,使炉时缩短6 h。The compressed air atomized diesel of traditional YANS burner has defects of low combustion efficiency and high pollutant emission,therefore,the multi-oxygen combustion technology was applied to the production practice of silver concentrate by pyrometallurgy,the unit consumption of diesel oil and emission of CO_(2) are all reduced by 50%,the unit consumption of sodium nitrate is reduced about 30 kg;The purification capacity at oxidizing refining stage is strengthened,the smelting time is shorten by 6 h.
