ZIRCOMAT

Zirconia Stack Oxygen Gas Analyzer

FOR harsh, dirty and “hot” environments

Our COSA XENTAUR™ Zircomat™ zirconia oxygen gas analyzers are widely used; not only in industries of high energy consumption, such as steel, power, petrochemical, ceramics, pulp and paper, food and beverage, and textile industries, but also in various combustion facilities, such as garbage incinerators and medium-to-small sized boilers, as combustion controllers, achieving a significant energy-saving effect. The oxygen concentration control ensures complete combustion, thus reducing CO2, SOx, and NOx emissions and helping prevent global warming and air pollution.

BENEFITS

Benefits of the Zircomat zirconia stack oxygen gas analyzers include:

  • High Accuracy: The zirconia sensor provides high accuracy and stability, even in harsh and variable process conditions.
  • Fast Response Time: Have a fast response time, typically less than one second, allowing for rapid process control.
  • Low Maintenance: The zirconia sensor is rugged and reliable, requiring minimal maintenance and calibration.
  • Wide Measurement Range: The analyzers can measure oxygen concentrations from trace levels up to 100%, making them suitable for a variety of applications.
  • Versatility: Are available in several models with different measurement ranges and options for sample conditioning, making them suitable for a wide range of applications in industries such as power generation, combustion control, and process control.
  • Easy Integration: The analyzers can be easily integrated into existing process control systems, with options for analog and digital outputs, as well as communication protocols such as Modbus and Profibus.

INDUSTRIES

Some of the industries that use the Zircomat zirconia stack oxygen gas analyzer include:

  • Power Generation: Commonly used in the power generation industry to measure oxygen concentration in combustion processes, such as boilers, turbines, and incinerators.
  • Petrochemical: The analyzer is also used in the petrochemical industry to monitor oxygen concentration in chemical processes, such as gasification, reforming, and cracking.
  • Metals: The analyzer is used in the metals industry to measure oxygen concentration in steelmaking and other high-temperature processes.

Rugged Zirconia Oxygen Gas Analyzer

APPLICATIONS



PROBE OPTIONS

Standard ZFK

    • The ZFK is designed for oil or gas fired operations with stack gas temperatures up to 1150ºF. This probe uses the natural pressure drop created from stack gas passing across the prove tip to deflect the sample gas past the oxygen detector for measurement. The detector detaches from the probe for service without removing the prove from the stack.

ZTB Self Cleaning

    • Designed for dirty applications with sample gas temperatures up to 1150ºF, the ZTB probe uses plant air to clean the detectors sample gas filter automatically at programmable time intervals and is recommended for coal and black liquor fired boilers or incinerator applications with high fly ash content. The detector detaches from the probe for service without probe removal.

ZFK-ST High Temperature

    • This probe is manufactured from ceramic and can be used on applications burning oil or gas as a fuel with stack gas temperatures up to 2200ºF. The detector detaches from the probe for service without removing the probe from the stack. For special applications, high temperature alloys can also be supplied.

ZTA High Temperature

      • The ZTA is used for sample gas temperatures up to 2900ºF and is available with a self-cleaning function. It uses compressed air to educt the sample from the stack. A built-in heater maintains the sample above the dewpoint during start-up. The detector detaches for service without probe removal.
