中文摘要:

(YQ ) Yangquan 的燃烧过程白煤与 0.045wt% , 0.211wt% , 1.026wt% ,和 2.982wt% 氯的增加被调查在空气气氛从周围的温度使用一个 thermogravimetric 方法到 1173 K。结果证明 YQ 燃烧特征没被氯内容的增加显著地影响。为燃烧变换获得的数据然后进一步为运动分析被处理。用没有模型的方法决定的平均明显的激活精力(明确地 KAS 方法) 分别地,是 103.025, 110.250, 99.906,和 110.641 kJ/mol,为描述包含氯的 YQ 的燃烧过程的最佳的运动模型是成核运动模型由 z() 主人阴谋方法决定了。运动模型当时是的成核的机制功能采用了估计 pre 指数的因素,由使用赔偿效果。描述包含氯的 YQ 燃烧的运动模型因此通过最佳的机制功能,平均明显的激活精力,和 pre 指数的因素的先进决心被获得。

英文摘要:

The combustion process of Yangquan anthracite(YQ) with the addition of 0.045wt%, 0.211wt%, 1.026wt%, and 2.982wt% chlorine was investigated using a thermogravimetric method from an ambient temperature to 1173 K in an air atmosphere. Results show that the YQ combustion characteristics are not significantly affected by an increase in chlorine content. Data acquired for combustion conversion are then further processed for kinetic analysis. Average apparent activation energies determined using the model-free method(specifically the KAS method) are 103.025, 110.250, 99.906, and 110.641 k J/mol, respectively, and the optimal kinetic model for describing the combustion process of chlorine-containing YQ is the nucleation kinetic model, as determined by the z(α) master plot method. The mechanism function of the nucleation kinetic model is then employed to estimate the pre-exponential factor, by making use of the compensation effect. The kinetic models to describe chlorine-containing YQ combustion are thus obtained through advanced determination of the optimal mechanism function, average apparent activation energy, and the pre-exponential factor.
