ZO-801S anti-corrosion zirconia oxygen analyzer

1、 Overview:

Due to the high concentration of corrosive gases, high temperature, high humidity, high dust, and strong corrosive media such as HCl and SO ₂ in the flue gas of garbage power plants, acidic substances are easily generated, which can easily corrode zirconia tubes. Zirconia tubes are the core components of instruments, and damage to them can lead to measurement errors and inaccurate data. So our zirconia probe needs to adopt an anti-corrosion design, using waterproof and anti-corrosion zirconium tubes, along with some process design,ZO-801S anti-corrosion zirconia oxygen analyzerThe probe is made of corrosion-resistant materials such as 316L and silicon carbide. Our company has a standard anti-corrosion zirconia oxygen analyzer process, which is specifically used in industries such as waste to energy plants, chemical plants, sulfuric acid plants, and hazardous waste environmental protection. It adopts thin film electrolysis technology, greatly increasing the service life of the product. If the flue gas contains dust and particles, our company's anti-corrosion probe can be equipped with a blowing device and wear-resistant processes, which play a key role in corrosion resistance and blockage prevention.

3、 Application:

(1) Optimize incineration efficiency, monitor the oxygen content at key points such as furnace outlet and waste heat boiler inlet in real time, adjust the primary and secondary air flow rates and grate operation speed in a coordinated manner, maintain an appropriate excess air coefficient, ensure full combustion of garbage, stabilize furnace temperature above 850 ℃, efficiently decompose harmful substances such as dioxins, and improve thermal energy recovery efficiency.

(2) To assist in achieving environmental standards, accurate oxygen content data can be used to convert the emission concentration of flue gas pollutants, meeting the requirements of environmental emission standards. At the same time, in conjunction with the operation of denitrification systems, it can improve denitrification efficiency and reduce emissions of pollutants such as NOx.
