炉内喷钙脱硫的模拟
- FSI(furnace sorbent injection) desulfurization modeling
- 摘要:煤粉炉内喷钙脱硫是应用较为广泛的脱硫技术,运用逾渗理论建立氧化钙脱硫模型,用来模拟煤粉炉喷钙脱硫过程,并对脱硫影响因素:SO2浓度、温度、Ca/S比等进行了研究,模拟计算显示了这些因素对脱硫效果的影响,其结果与试验数据相一致。通过该模型计算可以优化脱硫过程,对煤粉炉内喷钙脱硫有重要的指导意义。
- Abstract:Furnace sorbent injection (FSI) is one of the widely-used desulfurization technologies.Based on percolation theory,CAO's desulfurization model was modified to simulate desulfurization process of furnace sorbent injection (FSI).Factors of desulfurization including SO2 concentration,temperature,Ca/S mole ratio were studied.Results of the model showed the effects of these factors on the SO2 removal.The SO2 removal efficiency varied with combustion temperature,SO2 concentration,and Ca/S mole ratio.They were in accordance with experimental data.Based on the model,desulfurization process can be optimized.
