氧化锆氧量分析仪在火电厂燃烧控制中的应用

Application of Zirconia Oxygen Analyzer for Combustion Control in Fossil-fired Power Plants

氧化锆氧量分析仪作为发电厂锅炉燃烧的监测仪表,在指导燃烧方面起着重要作用。因此,必须维护好氧量分析仪,使它经常处于正常的工作状态,并能准确测量出氧含量的大小。分析了氧化锆氧量分析仪的主要结构、作用原理,探讨了国内外不同氧化锆氧量分析仪在测量准确度、使用寿命等方面存在较大差异的原因,最后得出造成这种现象的主要因素是材质和制造工艺上的差距。

Zirconia oxygen analyzer is the monitoring instrument for boiler combustion in power plants, it plays a significant role in directing combustion. Thus it is necessary to well maintain the analyzer to keep it in normal operational conditions for measuring content of oxygen precisely all the time. The main structure and operational principle of zirconia oxygen analyzer are analyzed ; and the reasons of big difference in measurement accuracy and life span existing among different zirconia oxygen analyzers made in China and other countries are investigated. Tbe conclusion obtained is the major factor which causes this is the materials and the technological process of fabrication.
