ABB 氧化锆分析仪 AZ25 AZ20 产品简介
The Endura AZ20 is the latest in a long line of high-quality, combustion gas analyzers from ABB.
The sensor, based on a zirconium oxide cell, is mounted at the tip of the probe that is inserted in the flue duct. The resulting direct, in situ measurement provides accurate and rapid oxygen reading for combustion / optimization and emissions monitoring purposes.
Endura AZ20 has been designed for extended periods of maintenance-free operation. The modular design with reduced component count improves the reliability and robustness of the system and simplifies breakdown repair if it occurs.
Kits containing all the parts needed to complete on-site repairs are available from ABB, ensuring that service personnel can effect repairs quickly and efficiently at minimum cost. The Endura AZ20probe has retained an easy-access cell arrangement, similar to the proven ZFG2 probe. This ensures cell replacement can be carried
out on-site using readily available, basic hand tools, even after long periods of high temperature operation.
The Endura AZ20 oxygen probe measures oxygen in flue gas using an in situ 'wet analysis' method. The 'wet analysis' method avoids measurement error (typically20% of reading higher than the actual value) that is by a sampling system using the 'dry analysis' method.
For customers with an existing installed ZFG2 probe with a ZMT or ZDT transmitter, a 55 V heater version of the Endura AZ20probe (the Endura AZ20 / ZFG2 replacement probe) is available.
System equipment comprises a (flue-mounted) Endura AZ20probe by an integral or remote transmitter. During operation, a zirconia cell within the probe is held at a constant temperature of 700°C (1292 °F) by a probe heater and
The Endura AZ25 combustion oxygen analyzer is the latest ina long line of high-quality, combustion gas analyzers fromABB. The AZ25 is designed to measure oxygen high temperature furnace atmospheres.
The sensor, based on a zirconium oxide cell, is mounted at thetip of the probe that is inserted directly into the furnace. Theresulting direct, in-situ measurement provides an accurate andrapid oxygen reading, for combustion / optimizationand process quality purposes.
The in-situ technique provides a true oxygen measurementinside the process. It eliminates 'equilibrium shift' that iscommon to systems in which gas samples are extracted andcooled before measurement.
Reference air (500 to 1000 ml/min [1 to 2 ft3/hr]) is required foraccurate operation and can be supplied from an ABBmains-powered pump unit or a flow regulator unit.
Unique integrated automatic calibration
The Endura AZ25 automatic calibration system eliminates theneed for the expensive ancillary equipment required forautomatic calibration on traditional flue gas oxygen analyzersystems. ABB’s fully integrated, automatic calibration feature
the test gas sequence and detects test gasavailability, eliminating incorrect calibrations due to loss of testgas. Integrated automatic calibration secures the oxygenmeasurement, providing complete confidence in the analyzer's
