Zirconia Oxygen Analysis Instrument Installation Guide: Choose The Appropriate Installation Point To Extend The Service Life

Zirconia oxygen analysis instrument, also known as Zirconia Oxygen Analyzer, zirconia analyzer, zirconia oxygen meter, zirconia oxygen meter, is a commonly used online oxygen measurement device that displays oxygen content and temperature. The high temperature used by the instrument The physical properties of zirconia have the characteristics of high measurement accuracy, strong stability, and low price. It can quickly and accurately display the oxygen content of flue gas generated during the combustion process of boilers, kiln heating furnaces and other combustion equipment online. , detection, and analysis to achieve low-oxygen combustion control, achieve energy conservation, and reduce environmental pollution. It is an oxygen analyzer widely used in industry. The following is a brief explanation of some precautions when installing Zirconia Oxygen Analyzer:

1. Selection of installation point

Choosing the appropriate mounting point has a great impact on the service life of the Zirconia oxygen analysis instrument. The flue gas temperature is required to meet relevant requirements to ensure long-term use of the detector. Generally speaking, the flue gas temperature is low and the service life is long, and the flue gas temperature is high and the service life is short. The Zirconia oxygen analyzer probe cannot be installed in a dead corner where flue gas does not flow, nor can it be installed in a place where flue gas flows quickly. In addition, the flue gas leakage is small and installation and maintenance are easy, which is an important condition for selecting the installation point. For medium and small boilers, it is recommended to install it before the economizer and after the superheater to better reflect the amount of flue gas oxygen in the furnace.

2. Fixing flange of analytical and testing instruments on the furnace wall

In order to ensure the fixation and stability of the Zirconia oxygen analysis instrument, a suitable fixing flange must be used. Normally, steel is used to make the transition frame. The flange of the transition frame can be directly welded to the furnace wall or embedded in the furnace wall, but it must be airtight and firm. The flange on the other end of the transition frame is designed to fix the detector, so it must match the screw hole of the detector fixing flange.

3. Installation of detector

The reference gas is very important when installing the detector. The detector needs to be installed horizontally, with the reference gas and standard gas interfaces facing downwards to ensure measurement accuracy. Rubber cardboard must be filled between the transition frame flange and the detector flange to prevent air from leaking into the flue and affecting measurement accuracy. The reference gas of Zirconia oxygen analysis instrument is provided by natural convection of air, ensuring a stable flue environment and appropriate detector installation, which are key factors to ensure the accuracy of detector detection.
