The zirconia analyzer is an in-line heating type with an overall stainless steel structure. It has the characteristics of high sensitivity, fast response speed and good stability. The zirconia analyzer can not only measure the residual oxygen in the boiler combustion process, but also be used for various thermodynamic studies, continuous monitoring of oxygen content in gas manufacturing plants, control of the combustion process of soaking furnaces, and oxygen in chemical plants and other production processes. Quantitative control analysis, etc.
Zirconia analyzer plays a more active role in reducing environmental pollution, saving energy and improving combustion efficiency. It is also an important means of project management and quality control. It is widely used in electric power, petrochemical, metallurgy and chemical fertilizers and other domestic boiler industries.
The working principle of the zirconia analyzer is that when the measured gas (flue gas) enters the inner side of the zirconia tube through the sensor, the reference gas (air) enters the outer side of the sensor through natural convection, when the oxygen concentration inside and outside the zirconium tube is different. Oxygen concentration potential is generated inside and outside the zirconia tube (in the case of reference gas determination, the oxygen concentration potential output by zirconia is a function of the operating temperature of the sensor and the concentration of the measured gas) The zirconia analyzer measures The electromotive force of the oxygen concentration difference is converted into a standard signal with a linear relationship with the oxygen content of the measured flue gas through the display instrument for display and output.
