The Multi-Channel Zirconia Oxygen Analyzer System delivers accurate O2 measurements utilizing Yokogawa’s zirconia oxygen analyzers for combustion monitoring and control, helping industries achieve lowered CO2, SOX, and NOX emissions. The oxygen analyzer system provides minimized downtime and simplified maintenance with advanced diagnostics, intuitive design and technician training, in addition to having the ability to connect up to eight probes to one analyzer.
The Multi-Channel Zirconia Oxygen Analyzer System includes the AV550G converter and ZR22 detector and is capable of measuring oxygen concentrations. The system includes all of the features of the single-channel system as well as additional functions such as averaging outputs and accessibility of all probes in one analyzer.
The ZR22G separate-type detector is an in-situ probe that uses a high-reliability zirconia sensor. The zirconia cell and heater assembly can be replaced in the field, reducing maintenance costs. The ZR22S separate-type detector for explosion-proof applications is also available and offers the following explosion-proof certifications:
The AV550G averaging oxygen analyzer is ideal for combustion control in large utility boilers and industrial furnaces and features a 5.7-inch color LCD touch screen, “hot-swappable” channel cards to minimize downtime and up to eight probe inputs. The AV550G can output the average oxygen concentration from a user-selected group of zirconia detectors, and detectors that are in alarm, calibration, or that are not in service, are automatically removed from the average output. This is especially useful when performing calibration or maintenance.
Predictive diagnostics from the analyzer simplify troubleshooting and provide technicians with the necessary data to create a minimal calibration schedule with the help of the smart calibration, asymmetry alarm, and trend graphing functions.
The probe's cell is designed with a large measurement surface area, making it less susceptible to contaminants, which allows for longer periods between cell replacements and calibrations.
The probe uses a long-life, high-reliability zirconia sensor and has an intuitive design that enables easy troubleshooting and repair in the field, minimizing downtime and reducing costs since technicians only need to replace the needed parts.
Yokogawa’s knowledgeable representatives and support technicians provide operation and repair training for all Yokogawa products both in the factory and in the field. Training ranges from basic operation to advanced troubleshooting, helping you achieve more efficient operations and simplified maintenance.
WZ-H cables are compatible with all ZR22, ZR402, and AV550G model Oxygen Analyzer Systems. The purpose of these cables is to transmit the signal from the sensor/detector to the analyzer. Additionally, the cabling provides for electrical input to the heater assembly within the detector for cell temperature control.
The accumulation of fly ash on the zirconia cell affects its ability to measure oxygen concentration. Fly ash and its constituents can reduce the life of the zirconia cell and affect the cells response time to changes in gas concentration. Yokogawa's large surface area sintered metal filters are designed to keep particulate and ash off the measurement cell.
Yokogawa's Zirconia oxygen detector systems offer a variety of calibration units for quick, easy control of calibration gases giving the user simple, accurate calibration.
Tantalum Capacitors are electrolytic capacitors that use a material called tantalum for the electrodes. Large values of capacitance similar to aluminum electrolytic capacitors can be obtained.
In a hot blast stove, the by-product gas produced in a coke oven is burned to preheat the air blast for the blast furnace. To improve the combustion efficiency and conserve energy in a hot blast stove, it is essential to be able to control combustion by measuring and adjusting the oxygen concentration in the exhaust gases.
