High temperature extraction zirconia oxygen analyzer

Zirconia oxygen analyzerModel List: In industries such as thermal power plants, waste to energy plants, chemical plants, steel plants, hazardous waste environmental protection, glass building materials, etc., precise measurement of oxygen content is the key to achieving efficient combustion, energy conservation, and emission reduction in industrial process optimization and environmental monitoring, optimizing production processes.Zirconia oxygen analyzerAs an intelligent instrument for online monitoring of flue gas oxygen concentration, the oxygen ion conductivity generated by zirconia ceramics at high temperatures is utilized to accurately calculate the oxygen content by measuring the potential difference caused by the difference in oxygen concentration on both sides. This intelligent instrument helps enterprises achieve low oxygen combustion control, achieving energy conservation, consumption reduction, and environmental pollution reduction.

Zirconia oxygen analyzerThere are many types, which can be divided into multiple models according to different installation methods, usage environments, and measurement principles.

Model:

(1) The TKFX-ZOA series (such as TKFX-ZOA/F) has direct insertion installation and can be selected for anti-corrosion/wear-resistant applications in petroleum, chemical, power, energy, environmental protection, etc.

(2) The ZO series (such as ZO-12B, ZO-801S) has a wide range of models, including wall mounted, disc mounted, wear-resistant, anti-corrosion, wear-resistant, and waterproof types.

(3) OXT series (such as OXT1000, OXT3000) OXT1000 is the standard type, OXT3000 is the anti-corrosion type for thermal power plants (standard type), and garbage/biomass power plants (anti-corrosion type).

(4) The FN series (such as FN3001B, FN3101B) uses imported zirconia sensors and intelligent signal converters for industries such as power, metallurgy, heating, and building materials.

(5) ZB-312 anti-corrosion design, specifically designed for garbage incineration, with low internal resistance, long service life, and a corrosive flue gas environment.

(6) ZFK8/ZRM1K/ZKM1 ZFK8 are direct insertion probes, while the latter two are wall mounted analyzers for online monitoring of thermal power plant environments

(7) The OCM6000 series explosion-proof design offers a wide range of probe length specifications for hazardous environments with explosion-proof requirements.

(8) YB-88 type: Low temperature type: YB-88GJ-DW-400, YB-88GJ-DW-600, YB-88GJ-DW-1000, YB-88G-DW-1200mm; High temperature type: YB-88G-GWP-1000, YB-88G-GWP-1200, direct insertion standard typeZirconia oxygen analyzerMade of 316L stainless steel and utilizing diaphragm electrolysis technology, it enhances its corrosion resistance and service life.

（9）ZO-801S 型Zirconia oxygen analyzerFor strong corrosive environments such as sulfuric acid production, there are specialized models such as ZO-801SZirconia oxygen analyzerThis model has been specially designed for the process characteristics of sulfuric acid plants.

(10) High temperature extraction zirconia analyzers such as NFZO-GW/FS, TKFX-ZOA/G, etc. can handle flue gas temperatures up to 1600 ℃, and reduce the impact of dust and high temperature on measurement through a sampling pretreatment system.

Response speed is an important indicator for measuring the dynamic performance of an analyzer. premiumZirconia oxygen analyzerThe response speed can be as fast as within 3 seconds, which can timely reflect changes in flue gas oxygen content and provide real-time data for combustion control. Installation dimensions include insertion depth and flange specifications. Common insertion depths include various specifications such as 300mm, 400mm, 500mm, 600mm, 800mm, 1000mm, 1200mm, etc. The flange size is usually DN50 (according to HG20592 standard), and can also be customized according to customer needs. The output signal is usually a 4-20mA current signal, used for remote transmission to DCS or PLC control systems. The analyzer also provides rich diagnostic functions, such as thermocouple open circuit, zirconium head heating abnormality and other alarms.

Selection precautions:

Choose the appropriateZirconia oxygen analyzerThe model needs to consider multiple factors to ensure that the instrument matches the specific application conditions.

Smoke conditions are the primary basis for selection. It is necessary to clarify the temperature, pressure, and composition characteristics of the flue gas (such as whether it contains corrosive gases, dust concentration, etc.).

For flue gas containing corrosive gases such as HF and HCl (such as waste incineration tail gas), a corrosion-resistant zirconia analyzer must be selected; For high dust flue gas, a porous ceramic filter needs to be installed.

Installation requirements directly affect measurement accuracy and maintenance convenience. The length of the sampling probe should reach one-third of the diameter of the flue to ensure representativeness of the sampling.

The sampling point should avoid the bottom of the flue to prevent the influence of dust accumulation, and choose a location that is easy to maintain and repair. It is also necessary to choose secondary instruments that are wall mounted, panel mounted, or vertically installed according to the on-site space.

Standard analyzers can be selected for ordinary industrial environments; Places with explosion-proof requirements (such as chemical and coal mining areas) must use explosion-proof zirconia analyzers.

Brand and service are also factors to consider when choosing a product. Imported brands (such as Rosemount, Ametek, Yokogawa, ABB, Watson, etc.) have stable performance but relatively high prices;

Domestic brands (such as Anhui Meikang, Shenzhen Langhong, etc.) have more competitive price advantages and more convenient after-sales services while ensuring product quality and performance.

Correct selection and useZirconia oxygen analyzerIt has important value in achieving energy conservation and emission reduction, improving combustion efficiency, and is also one of the technical guarantees for industrial enterprises to achieve sustainable development.
