摘要

在实验室规模的小型立式旋风筒中

对工业制备的内蒙古锡林浩特褐煤半焦的贫氧旋风燃烧特性进行了试验研究。结果表明:在过量空气系数为0.5~0.9时

贫氧燃烧产物的热值在1 500~3 500 kJ/m3之间

且随着过量空气系数的增加而降低；随着过量空气系数增加

半焦燃烧碳转化率增高

当过量空气系数＞0.6时

半焦燃烧碳转化率＞97%

炉内燃烧区温度升高

在过量空气系数为0.7时

燃烧区温度可达1 280 ℃

高于灰熔点

这对保证液态排渣非常关键；给料量增加对半焦燃烧特性影响不大

表明旋风筒燃烧室对燃烧褐煤半焦具有良好的负荷调节特性；贫氧燃烧条件下

旋风筒NO的排放质量浓度较低

随着过量空气系数和给料量的增加

旋风筒NO的排放质量浓度提高。
