摘　　要：在晶粒模型的基础上建立了用于描述中温烟气 (4 0 0℃～ 80 0℃ )生石灰脱硫过程的数学模型 ,并进行了求解及模型的验证。通过该模型的计算可以更好地了解中温区域内生石灰脱硫反应的进程和反应机理。采用该模型初步探讨了几种物理参数的变化对钙转化率的影响。A model used to simulate the sulphur absorption reaction of middle temperature (400-800°C) flue gas with lime has been established based on the grain model. The rationality of the model is examined by making comparison between the calculated values of the model and the experimental results. The effect of some parameter on the conversion of CaO is analyzed. The establishment of this model lays the initial foundation of the development of sulphur absorption technology in middle temperature region.
