摘　　要：煤燃烧过程中的硫分析出特性受自身硫分组成、外部燃烧状况等多种因素的影响,通过分析硫分的析出规律,建立了硫分析出的统一动力学模型,对比研究了2种不同煤样在不同反应级数下的析出模型,通过origin软件作图计算得出,一级反应是最适合硫分析出的动力学模型。硫分析出动力学方程的建立对煤燃烧过程中有效控制气态硫的排放提供了参考依据。The characteristic of sulphur releasing is influnced by a lot of factors such as： sulphur composition, external combustion conditions and so on. This paper set up the dynamical model of sulphur releasing though analyzing its releasing law and studied sulphur releasing model of two kind of coal samples in different reaction order. The research results of mapping and calculating through origin software show that the firstorder reaction is most suitable for the dynamical model of sulphur releasing. The foundation of the dynamics equation offered reference basis for controlling effectively gas sulphur releasing during coal combustion.
