1000MW电站锅炉SCR喷氨优化试验分析
摘要
论述了超临界电站锅炉喷氨优化过程
根据烟道内NOX浓度分布规律
有针对性的调整喷氨系统
从而降低了喷氨量
提高了SCR出口NOx分布均匀性
降低了氨逃逸浓度
减小了硫酸氢氨对空气预热器的腐蚀风险
并提高了脱硝效率。
Abstract
Discusses the optimization experiments for supercritical boilers
according to the distribution of NOX
we adjust ammonia system
reduce the amount of injecting ammonia
the distribution uniformity of NOX at SCR outlet is improved
ammonia escape concentration is reduced
the impact of ammonium hydrogen sulfate to the air preheater is reduced and denitrification efficiency is improved.
