ABB expands combustion gas analysis capabilities with new oxygen probe
Combustion gas analyzers for industrial and utility boiler applications.
ABB Measurement Products has launched its next generation of combustion gas analyzers for industrial and utility boiler applications. Featuring a revised sensor design and an increased choice of probe lengths up to 4 metres (13.12 feet), the Endura AZ20 expands ABB’s offering to a new range of high temperature applications up to 800°C.
A key feature of the Endura AZ20 is its enhanced robust design. Manufactured using a new ceramic-to-steel bonding process, the AZ20 offers improved resistance to thermal stresses and shocks compared to a conventional brazed design. This enables it to be used in a wider range of applications subject to sudden variations in process temperature, as well as offering a gas tight bond throughout its operating temperature range.
The Endura AZ020 benefits from a unique cell processing technique which bonds the multi-layered platinum electrode to the zirconia. This means that the AZ20 can be used in arduous applications subject to sulphurous and reducing atmospheres such as sulphur recovery processes, crematoria and industrial and clinical waste incineration.
The strength of the AZ20 has been further enhanced by its reduced component count. With fewer parts requiring servicing or replacement, the AZ20 offers simplified maintenance. In the event that problems do occur, the AZ20’s NAMUR compliant diagnostics, with alarms and warnings in clear text, enables operators to quickly trace and rectify the fault.
Operation has been simplified by the use of ABB’s new universal Human Machine Interface (HMI), which has now been extended across its range of instrumentation products. Enabling operators to easily scroll through and select options, the HMI simplifies operation, maintenance and training, reducing cost of ownership and providing a consistent user experience. “Through-the-glass” control technology provides a local operator interface for inputting short, quick data for all user specific parameters without removing the transmitter cover.
As a HART-enabled device, the Endura AZ20 also offers the ability for operators to perform online modification and monitoring of parameters.
Improved process control is ensured by the positioning of the zirconium oxide measuring sensor at the tip of the probe, which is then inserted into the flue duct. This offers the ideal position for direct in-situ measurement, enabling users to get an accurate and immediate oxygen reading for optimizing the combustion control process.
Another new feature is the inclusion of integrated advanced calibration technology, which automatically controls both the test gas flow rate and test gas sequences during calibration
testing. This eliminates the need for expensive ancillary equipment typically needed for traditional flue gas oxygen analyzer systems and prevents incorrect calibrations caused by the loss of test gas.
As a leading manufacturer and supplier of a comprehensive range of instrumentation technologies, ABB is well placed to offer advice and guidance on the best analyzers for your application. For more information, please call 0870 600 6122 or email: moreinstrumentation@gb.abb.com ref. ‘analyzers’.
