摘要
灰钙循环烟气脱硫技术是煤炭科学研究总院针对高效煤粉工业锅炉自主研发的烟气脱硫技术,其反应器阻力是影响装置运行的重要因素,涉及相关设备选型、循环灰量和增湿水量的连锁保护控制。采用k-ε湍流模型对灰钙循环烟气脱硫反应器进行了数值模拟,确定了设计脱硫反应器的空床阻力,结果表明进料口前阻力占反应器总阻力大于90%。并对其结果进行了实验验证,结果证明模拟结果可靠,反应器设计合理,该阻力对锅炉燃烧不产生影响,同时可保证脱硫设备安全稳定运行。
FGD ash ＆ calcium circulating reactor is a flue gas desulphurization technology developed by CCRI for effi- cient pulverized coal industrial boiler. The reactor resistance is a key factor affecting reactor operation. The k - ~ turbu- lence model is used in the numerical simulated for the ash ＆ calcium circulating flue gas desulfurization reactor to get its empty bed resistance. The results show that more than 90 percentage of total resistance is the feed port resistance which be verified by an experiment. The resistance does not affect the boiler combustion, while ensuring safe and stable operation of desulfurization equipment.
