【摘要】 在循环流化床内物料浓度模型的基础上，重点进行了循环床内煤的燃烧数学模型的研究，并借助模型考察了几个重要因素对循环床燃烧过程的影响。模型对煤在循环床的密相区和稀相区的燃烧过程采用了不同的处理方法．模型计算结果与实验结果基本吻合，证明了模型的可靠性。更多还原

【Abstract】 On the basis of the particle concentration model in circulation fluidized bed, this paper emphatically studies a mathematical model of coal combustion in circulation fluidized bed and investigates the influence of some important factors on the combustion process by the model. Different methods are taken for the model to deal with coal combustion process at dense phase zone and dilute phase zone of circulation fluidized bed. The model calculated results accord with the experiment, which proves the reliability of the model.更多还原
