中文摘要	建立燃烧福建无烟煤循环流化床锅炉炉内脱硫的二步法反应模型,并与一步法反应模型进行比较。计算发现,模型的预测结果与工业实际运行测量数据基本吻合,能够反应脱硫效率随钙硫比的变化趋势:钙硫比较小时变化缓慢,只有当钙硫比较大时(>2.2)才有明显提高。与一步法反应模型相比,在钙硫比较小的情况下,该模型的计算结果与工业实测结果吻合更好;另外,由于考虑了石灰石煅烧的影响,该模型更能反应出负荷变化对脱硫效率的影响。模型计算表明,在保持钙硫比不变的条件下,脱硫效率随流化速度的增加而降低,随物料循环流率的增加而提高,随燃烧温度的升高而增加,但随负荷波动的变化较小。; A two step reaction desulphurization model of circulating fluidized bed(CFB)boiler burning Fujian anthracite was established.The model was validated against industry experiments and showed that it could predict the tendency of the variation of desulphurization efficiency with Ca/S mole ratio well:the desulphurization efficiency increases slowly when Ca/S mole ratio is under 2.2,but increases rapidly when Ca/S mole ratio is bigger than 2.2.The model was also compared with that of one step reaction model,it shows that when Ca/S mole ratio is small(<2.2),the result calculated from two step reaction model would fit the industrial experimental data better than that calculated from one step reaction desulphurization model.Due to considering the effect of limestone decomposition during combustion,the two step reaction model is better than the one step reaction model in describing the effect of load variation on desulphurization efficiency.Numerical simulation also indicates that,when Ca/S mole ratio is hold constant,the desulphurization efficiency would reduce as the flue gas velocity in furnace’s chamber increase,and increase when the materials circulation rate grows;with the rising of combustion temperature,the desulphurization efficiency would also increase,but with the increment of boiler’s load,the desulphurization efficiency increase slowly.; 【作者单位】集美大学机械工程学院；东华大学环境科学与工程学院；东华大学环境科学与工程学院福建省厦门市361021；上海市长宁区200051；【作者英文名】HE Hong-zhou1,SHEN Liang-kun2,SU Ya-xin2(1.School of Mechanical Engineering,Jimei University,Xiamen 361021,Fujian Province,China;2.School of Environmental Science & Engineering,Donghua University,Changning District,Shanghai 200051,China)
