Description ZR22G-100-S-C-E-T-Q-E-A YOKOGAWA Zirconia Oxygen Analyzer Detector Product Dimensions： Product Description (Detailed Explanation) The ZR22G utilizes the principle of a Zirconia solid electrolyte cell. At high temperatures, oxygen ions can move through the zirconia element. When there is a difference in oxygen partial pressure between the reference air side and the process gas side, an electromotive force (EMF) is generated. This EMF is measured and converted into an oxygen concentration percentage. The suffix code -100-S-C-E-T-Q-E-A specifies a highly customized configuration, including a 1.0-meter insertion length, specific flange requirements, and specialized material treatments for durability in corrosive environments. Product Parameters (Technical Specifications) Parameter Category Specification Measurement Target Oxygen concentration in flue gas Measurement Method Zirconia solid electrolyte (Oxygen concentration cell) Insertion Length 1.0 Meter (-100) Measurement Range 0 to 100% $O_2$ (Standard range 0-25%) Sample Gas Temp 0 to 700°C (Standard) Sample Gas Pressure -5 to 5 kPa Repeatability ±0.5% of Maximum Scale Linearity ±1% of Maximum Scale Reference Air Supply Natural convection or Instrument Air Enclosure IP66 (NEMA 4X equivalent) Product Advantages (Key Benefits) Direct In-Situ Measurement: Unlike sampling systems, the probe is inserted directly into the flue, eliminating the need for gas sampling lines and reducing maintenance complexity. High Durability: The zirconia cell is highly resistant to thermal shock and can withstand the harsh, high-temperature environments of industrial furnaces. Replaceable Heater & Cell: The heater and zirconia cell are designed for easy on-site replacement, which significantly reduces the Total Cost of Ownership (TCO). Excellent Long-term Stability: Due to the stable nature of the zirconia electrolyte, the sensor maintains high accuracy with minimal calibration drift. Range-Free Compatibility: Supports a wide variety of process conditions through modular suffix options, making it versatile for different global industrial standards. Precautions (Important Notes) Heater Safety: The probe contains an internal heater that operates at over 600°C. Never handle the probe while it is powered on or immediately after shutdown. Condensation: Ensure the detector is installed at an angle (usually 5° to 90° downward) to prevent condensation from accumulating on the zirconia cell, which can cause cracking. Calibration Gas: Regular calibration with a standard gas (e.g., 1% $O_2$ in $N_2$) is required to ensure accuracy. Check the calibration gas piping for leaks to prevent false readings. Corrosive Gases: While durable, high concentrations of $SO_2$ or $HCl$ in the flue gas can shorten the lifespan of the cell. Specialized filters or ceramic coatings should be used in such cases. Product Applications (Typical Use Cases) Power Plants: Monitoring combustion efficiency in coal-fired and gas-fired utility boilers. Steel & Metal Processing: Controlling the atmosphere in reheating furnaces and soaking pits to minimize oxidation of metal. Waste Incinerators: Measuring excess oxygen to ensure complete combustion of hazardous materials and to monitor emissions. Refineries: Managing oxygen levels in process heaters and crackers to optimize fuel consumption and reduce carbon footprint. Pulp & Paper: Controlling the recovery boiler performance for chemical recycling and energy recovery.
