摘要

基于锅炉排烟含氧量、附加燃尽风风量、燃尽风风量等运行因素对机组脱硝经济性的影响

建立了锅炉低氮燃烧与SCR脱硝系统联合运行的综合成本模型

通过锅炉低氮燃烧调整试验与SCR脱硝特性试验获取机组的运行特性及模型参数

开发了以机组脱硝运行综合变动成本最小为目标的脱硝运行优化系统

实现了机组脱硝优化运行在线指导。试验验证及应用结果表明:脱硝运行优化系统给出的运行方式合理；A电厂2号机组按脱硝运行优化系统给出的运行方式调整后

灰渣平均含碳量减少了32%

锅炉效率提高约0.28%

氨耗量增加约23 kg/h

综合节省费用约240元/h；B电厂3号机组调整后锅炉效率基本不变

尿素耗量下降约49 kg/h

综合节省费用约180元/h。
