Product Description
- Zirconia Sensor Element: The core component is a zirconium dioxide (zirconia) ceramic, typically doped with yttria, that functions as a solid electrolyte. When exposed to high temperatures, zirconia allows oxygen ions to move through its lattice structure, generating a voltage that corresponds to the oxygen concentration.
- High Temperature Tolerance: These analyzers work effectively at high temperatures, often above 600C (1112F), making them suitable for environments like flue gas, combustion chambers, and kilns.
- In-Situ Installation: As an in-situ device, it measures directly within the gas flow. This design eliminates the need for sample extraction and conditioning, making it quicker to respond to changes in oxygen levels.
- Electrochemical Principle: Zirconia-based analyzers leverage the Nernst equation, which relates the EMF (voltage) generated across the zirconia electrolyte to the partial pressure of oxygen in the measured gas.
- Fast Response Time: Due to the direct measurement approach and high-temperature functionality, these analyzers offer a fast response time, critical for controlling combustion processes efficiently.
Applications
- Combustion Control: Used in power plants, cement kilns, steel manufacturing, and petrochemical industries to optimize combustion, reduce emissions, and improve fuel efficiency.
- Process Safety: Monitoring oxygen levels to prevent explosive mixtures or ensure safe operating conditions.
- Environmental Compliance: Helps in maintaining low oxygen levels to control NOx and CO emissions.
Benefits - Real-Time Measurement: Instantaneous data helps optimize processes.
- Low Maintenance: Limited or no need for gas sampling lines, reducing downtime.
- Durability: Designed for continuous operation in challenging industrial environments.
In-situ zirconia-based oxygen analyzers provide essential control and monitoring capabilities in various high-temperature industrial processes, ensuring both efficiency and safety.
