意大利 ADEV OxyPink 氧化锆烟气分析仪
OxyPink 是一款高度创新的氧化锆探头,是唯一能够在 0°C 至 1250°C 整个温度范围内测量烟气中残余 O2 浓度的探头,这得益于简单但非常先进的集成加热系统,由外部电子设备管理。
这种完全由陶瓷制成的弹性原位分析仪能够承受最恶劣和多尘的过程条件,专为火化炉和焚化炉而设计,但它是所有燃烧过程的理想解决方案,其中探头必须始终保持在线状态,无论哪种情况是烟气温度。
可测量气体

测量原理
分析所依据的测量原理与氧化锆的使用有关,氧化锆在高温下可以表现得像固态电解质,在与不同 O 2浓度接触的两个电极上产生电动势 (EMF)(分压),与以开尔文度 (°K) 为单位的温度以及两个压力 PO 2 ‘ 和 PO 2 ”之间比率的对数(根据能斯特众所周知的比率)成正比:
E = RT / nF (ln P0 2 ‘ / P0 2 ‘)
其中: R = 完美气体常数(8.31 焦耳/度体积)
F = 法拉第常数
T = 绝对温度(°Kelvin)
