基于氧泵原理的氮氧化物监测仪的性能评价

Performance Evaluation of a Nitrogen Oxides (NO_x) Monitor with Zirconium Oxide (ZrO₂) Oxygen Pumping Sensors

摘要: 介绍了基于氧泵原理的氮氧化物监测仪，并对其性能进行评价。结果表明，该氮氧化物监测仪的准确度较高、重复性和稳定性较好，同时受环境影响小，在小锅炉氮氧化物排放连续监测和工业过程控制中具有较高的应用价值。

Abstract: This paper describes the concept and performance evaluation of an NO_x monitor with ZrO₂ oxygen pumping sensors. Test results showed that the NO_x monitor presented good repeatability, accuracy, and stability, and it was seldom affected by the environment. It suggested that the NO_x monitor could be used in the continuous monitoring of NO_x in exhaust gases produced by industrial processes.
