摘　　要：针对燃煤电厂SCR烟气脱硝技术改造后空气预热器堵塞的问题,提出减少喷氨量和空气预热器吹灰等措施,并分析在线高压水冲洗、高负荷连续运行、冷端连续吹灰的处理效果处理,认为高压水冲洗、冷端连续吹灰可有效降低空气预热器堵塞问题。This paper mainly introduces the SCR flue gas denitrification technology in coal-fired power plant after the operation of the air preheater in the operation of the blockage problem,and puts forward a feasible solution,considers that the high voltage online watering and cold-point soot blowing can solve blocking through analysis.
