Description

AZ20/AZ25 ABB In-situ Zirconia Oxygen Analyzers

Product Dimensions：

Product Overview

The ABB AZ20 and AZ25 are high-performance in-situ zirconia oxygen analyzers used for continuous oxygen measurement in combustion control and flue gas monitoring applications. These analyzers are installed directly into the process duct or stack, enabling real-time measurement of O₂ levels, helping to optimize fuel usage, reduce emissions, and improve safety.

  • AZ20: Standard in-situ oxygen analyzer with a compact design.

  • AZ25: Dual-sensor in-situ oxygen analyzer for improved accuracy and redundancy in safety-critical applications.

Both models use a zirconium oxide (ZrO₂) cell for fast, accurate oxygen measurements at high temperatures.

Product Advantages:

  • High Accuracy & Fast Response: Real-time oxygen measurement for efficient combustion control.

  • In-Situ Measurement: Eliminates the need for complex sampling systems.

  • Low Maintenance: Rugged sensor design with long service life.

  • Smart Diagnostics: Built-in diagnostics reduce downtime and simplify maintenance.

  • Dual Sensor Option (AZ25): Enhanced safety and redundancy for critical applications.

  • Communication Protocols: HART and Modbus allow for easy integration into DCS/PLC systems.

Precautions:

  • Proper Positioning Required: Install the sensor in a representative flue gas location.

  • Avoid Contaminants: Do not expose the sensor to silicon, lead, or phosphorus-containing compounds.

  • Initial Warm-Up Needed: Sensor must reach operating temperature before accurate readings are available.

  • Handle with Care: Zirconia sensors are sensitive to mechanical shock.

  • Follow Calibration Schedule: Regular calibration is necessary for long-term accuracy.

Typical Applications:

  • Power Plants: Boiler combustion optimization and NOx reduction.

  • Petrochemical & Refineries: Furnace and reformer air/fuel ratio control.

  • Chemical Processing Plants: Emission monitoring and safety assurance.

  • Cement & Steel Industry: Kiln and furnace O₂ monitoring for energy efficiency.

  • Waste Incineration Plants: Combustion monitoring for regulatory compliance.
