基于多点实时在线监测原理的精准喷氨技术在脱硝系统中的应用

Research and Application of Accurate Ammonia Injection Technology Based on Multi-point Real-time Online Monitoring Principle in Denitration System

通过在脱硝进出口烟道加装多点实时在线烟气监测系统,对氨喷射系统进行分区改造和调整,实现全负荷工况下的脱硝喷氨系统的自动投入,降低脱硝还原剂消耗,取得了良好的应用效果。

By installing a multi-point real-time online flue gas monitoring system in the denitrification inlet and outlet flue,the ammonia injection system is modified and adjusted in zones to realize the automatic input of the denitrification ammonia injection system under full load conditions and reduce the consumption of denitrification reducing agent,And achieved good application effects.
