【摘要】 在总结已有模型的基础上 ,考虑到 Ca O孔隙结构参数在反应过程中的变化 ,提出了 Ca O硫化反应的特定层数晶粒模型。通过对文献报道的实验结果和作者的实验结果进行比较 ,发现两者吻合较好 ,表明该模型预报炉内喷射超细 Ca O粉脱硫过程是可信的。这对于选择最佳的脱硫工况具有一定的指导意义更多还原

【Abstract】 New concepts for estimating the sulfation of CaO at high temperatures,namely a subgrain layer model,are presented in this paper.In the model the change of pore structure of CaO during the reaction process has been considered.The calculations made agree well with the experimental CaO sulfation data from the literature and those obtained in an entrained flow reactor by the authors.It is useful to select the best situation for desulfurization.更多还原
