烟气脱硝在线连续监测系统应用探索

摘要

脱硝在线连续监测系统与脱硫在线监测系统相比,脱硝装置在电除尘（或袋除尘）装置之前,而脱硫装置在除尘装置之后。由于安装位置的前移,脱硝CEMS系统运行环境将比脱硫CEMS系统更为恶劣,脱硝装置将面临着高温、高粉尘、高负压等一系列问题。本文结合脱硝装置工况及有关环保标准,提出了脱硝CEMS系统对设备的要求以及设备维护中的问题。%The maintenance of continuous emission monitoring system of denitration is much more difficult to the system of desulphurization. The CEMS of denitration will suffer from the problems, such as high temperature, high dust, high negative pressure and so on. This paper proposes the requirements for equipmen.t of the CEMS of denitration, according to the condition of denitration system and the environmental standards.
