不同品质煤的着火动力学参数研究

Study on Ignition Kinetic Parameters of Different Property Coal

主要针对水泥分解炉内的燃烧工况对不同煤质的煤的着火动力学参数进行了研究。结果表明:从无烟煤、贫煤、烟煤,其反应速率越来越大,着火活化能越来越低。干燥无灰基固定碳含量增加,其着火活化能逐渐升高,反应速率逐渐降低。

Ignition kinetic parameters of different property coal in calciner of cement kiln were discussed in this paper. The research showed that for anthracite, lean coal and bituminous, the reaction rate became larger and the ignition activation energy became smaller. With the carbon content of dry ash-free basis increasing, the ignition activation energy increase and the reaction rate fall.
