摘　　要：黄磷生产过程中产生的黄磷尾气富含高浓度CO、H2,是非常好的燃料。实验研究了应用黄磷尾气烧制石灰时,黄磷尾气的杂质含量和燃烧特性对石灰活性度的影响。实验结果表明,石灰活性度随着黄磷尾气杂质含量的降低而增大;随着石灰窑燃烧梁的温度和黄磷尾气中CO含量的增加而增大,在CO含量为92%时、空气过剩系数为1.3时,石灰活性度达到《冶金石灰标准》(YB/T 042-2014)普通冶金石灰一级标准。Yellow phosphorus tail gas, created during the production of yellow phosphorus, contains high concentrations of CO and H2 , and is a very good fuel. An experimental study examined the application of yellow phosphorus tail gas fired lime, the impact of impurity content, and combustion characteristics of yellow phosphor- us tail gas on the activity of lime. The experimental results show that the lime activity increases with the de- creased impurity content of yellow phosphorus tail gas. The lime activity increases with the temperature of the burning beam of the lime kiln and the content of CO in yellow phosphorus tail gas. When the content of CO was 92% , the excess air ratio was 1.3, and lime activity was up to the Standard of Metallurgical Lime （YB/T 042- 2014） , general metallurgical lime first class standard.
