Principle And Application Of Zirconia Flue Gas Oxygen Analyzer

The Zirconia flue gas oxygen analyzer is an instrument used to measure the oxygen content of gases in high-temperature furnaces. Its principle is based on the electrochemical reaction of oxygen ion transfer. When the gas passes through the zirconia oxygen probe, the oxygen molecules in it react with the oxygen ions on the sensor surface, causing the electrical potential on the sensor to change. This potential change is proportional to the concentration of oxygen molecules in the gas.

The zirconia flue gas oxygen analyzer consists of two main parts: the zirconia oxygen probe and the electronic control unit. The zirconia probe consists of a stable oxygen ion sensor and a bottom-closed tube that passes into the gas being measured. By precisely measuring the change in electrical potential across the sensor, a zirconia oxygen analyzer can accurately determine the oxygen content in a gas.

Diversion zirconia oxygen probe: Use a long diversion tube to introduce the measured gas into the zirconia oxygen probe, and then the heating element heats the zirconia to the working temperature (above 700°C). Zirconia is generally in the shape of a tube, and the electrode is a porous platinum electrode. Therefore, it is not affected by the temperature of the detected gas, and the oxygen content in gases of various temperatures can be detected by using different guide tubes.

Zirconia flue gas oxygen analyzer has a wide range of applications, especially in industrial fields. It can be used to monitor the oxygen content of gases during combustion to optimize energy utilization and reduce environmental pollution. By monitoring the oxygen content during the combustion process in real time, operators can adjust the fuel supply in a timely manner to ensure that combustion efficiency and environmental emissions meet requirements.

In short, the principle of Zirconia flue gas oxygen analyzer is simple and reliable, and its application fields are wide and diverse. In addition to combustion process monitoring and environmental monitoring in the industrial field, zirconia oxygen analyzers also play an important role in many other fields.
