ABB AZ20 Zirconia Oxygen Analyzer System
The ABB AZ20/.1.1.2.1.1.2.1.2.1.1.1.21.0.0.E./ST is a zirconia-based oxygen analyzer system designed for industrial combustion and flue gas monitoring applications. It is part of ABB’s advanced process gas analysis portfolio used for continuous oxygen measurement in high-temperature industrial environments where combustion efficiency and emissions control are critical operational factors.
In industrial combustion systems, oxygen concentration is one of the most important parameters for controlling fuel efficiency and ensuring complete combustion. Excess oxygen leads to energy loss, while insufficient oxygen results in incomplete combustion and increased emissions. The ABB AZ20 system provides continuous real-time oxygen measurement to help maintain optimal combustion balance and stable process performance.
This specific configuration represents a structured system definition that includes functional settings, hardware arrangement, and application-oriented parameter mapping. It allows the analyzer to be adapted to complex industrial conditions while maintaining consistent measurement reliability and operational stability.
Industrial Combustion and Flue Gas Monitoring
The ABB AZ20 zirconia oxygen analyzer is widely applied in industrial combustion environments where precise oxygen control is required for safe, efficient, and environmentally compliant operation. It is commonly installed in systems that rely on boilers, furnaces, and high-temperature combustion processes.
Continuous oxygen monitoring enables operators to adjust air-to-fuel ratios in real time, improving combustion efficiency and reducing fuel consumption. This leads to better energy utilization and lower operating costs across industrial facilities.
Typical application areas include power generation plants, cement production kilns, steel manufacturing furnaces, waste incineration systems, and chemical process combustion units. In all these environments, oxygen measurement is essential for maintaining stable combustion conditions and minimizing emissions.

Zirconia Oxygen Sensing Technology
The ABB AZ20 system utilizes zirconia oxygen sensing technology, which is widely recognized for its reliability in high-temperature gas analysis applications. Zirconia sensors operate based on electrochemical principles, measuring the difference in oxygen concentration between reference air and flue gas streams.
This generates a stable electrical signal proportional to oxygen concentration, enabling accurate and continuous measurement even in harsh industrial conditions. The technology provides fast response times, making it suitable for real-time combustion control applications.
Because zirconia sensors operate effectively at high temperatures, they are ideal for flue gas environments where conventional sensing technologies may fail. This ensures consistent performance in demanding industrial processes.
Stable oxygen measurement helps prevent combustion inefficiencies such as fuel waste, incomplete oxidation, and excessive pollutant formation.
Process Optimization and Operational Benefits
The ABB AZ20 oxygen analyzer supports industrial operators in optimizing combustion processes through continuous oxygen feedback. This enables precise control of air-to-fuel ratios, improving both energy efficiency and environmental performance.
One of the key benefits is reduced fuel consumption. By maintaining optimal oxygen levels, combustion systems can operate with minimal excess air, improving thermal efficiency and reducing operational costs.
In addition, accurate oxygen monitoring contributes to emissions reduction by minimizing pollutants such as NOx and carbon monoxide. This is increasingly important for meeting environmental regulations and sustainability targets.
The system also enhances process stability by providing real-time data that supports automatic control adjustments in combustion systems.
