ABB Endura AZ30 Combustion gas oxygen analyzer
Overview
The ABB Endura AZ30 oxygen analyzer for combustion gas is engineered to measure oxygen concentration directly in hot flue gases. With high-temperature zirconia sensor technology, the AZ30 delivers accurate, continuous oxygen readings without the need for gas sampling or conditioning systems.
The rugged stainless steel probe and built-in calibration port make it ideal for harsh industrial settings such as boilers, incinerators, and kilns, where combustion efficiency depends on reliable oxygen data.
Engineering & Design
The in-situ probe design places the zirconia sensor directly in the flue gas stream, eliminating the sample line, pumps, and conditioning equipment of extractive systems. This reduces maintenance and provides fast response to changes in combustion conditions.
The analyzer helps reduce fuel consumption, control emissions, and enhance combustion efficiency, and it is fully compatible with a wide range of process control systems through its analogue and communication interfaces, including remote diagnostics for extended operational lifespan.

Combustion efficiency depends on oxygen measurement, and the ABB Endura AZ30 oxygen analyzer provides the data, which is why Seven Star LLC supplies the ABB Endura AZ30 oxygen analyzer for boiler projects.
For combustion measurement, the ABB Endura AZ30 oxygen analyzer is an in-situ choice that measures directly in hot flue gas. Seven Star LLC supplies the AZ30 with a range of probe options.
The ABB Endura AZ30 analyzer measures the oxygen in the flue gas with the zirconia cell at the probe tip and the control unit on the wall. The probe is inserted into the boiler duct through the mounting flange, and the control unit displays the measured oxygen and provides the 4-20 mA output. The automatic calibration with the reference gas keeps the reading stable over the long operation period.
Why Seven Star LLC
Seven Star LLC supplies the ABB Endura AZ30 oxygen analyzer for combustion projects across the Gulf, with verified specifications and technical support. Our team assists with probe selection, integration, and calibration planning for boilers and kilns.
We serve power, chemical, and metal industries with reliable B2B supply of combustion analyzers throughout the GCC.
Installation & Operation
The in-situ probe is installed directly through the flue duct wall, placing the zirconia sensor in the hot gas stream. The built-in calibration port supports gas calibration without removing the probe, and the stainless steel construction withstands the flue gas environment.
Remote diagnostics and process control integration allow the analyzer to be monitored from the control room, and the fast response supports trim control of combustion air for efficiency and emissions compliance.
Supply Chain & Sourcing
Seven Star LLC supplies the ABB Endura AZ30 backed by genuine ABB supply, including the probe configurations and calibration accessories for your boiler application.
Our team supports the selection of probe length and integration options.
The probe is serviced by removing the sensor assembly for inspection, and the calibration port allows the zirconia cell to be verified with reference gases.
The analyzer electronics provide the oxygen signal and diagnostics to the control system, supporting the combustion trim strategy that reduces fuel consumption and emissions in boiler and kiln operation.
For multiple boilers, the analyzer configuration can be repeated across the units, and the common spare part strategy reduces the stock required. The probe length is selected for the duct geometry of the application.
The AZ30 combines the low maintenance of in-situ measurement with the accuracy of zirconia technology, supporting the combustion efficiency programmes of industrial plants.
The Endura AZ30 serves the combustion measurement needs of industrial boilers and kilns with a proven in-situ design.

Selecting the Right AZ30 Probe Configuration
The AZ30 is supplied in several configurations, so the order should start from the process rather than the catalogue. The key inputs are the flue gas temperature at the proposed mounting point, the duct or stack dimensions, the fuel being fired and whether the gas carries dust or corrosive components. Probe insertion length should place the sensor well into the representative gas flow, away from wall effects and air in-leakage. When replacing an existing unit, the probe and transmitter nameplates give the full order code, which is the most reliable way to match length, flange and electronics.
- Flue gas temperature and pressure at the sampling point
- Duct size, wall thickness and available nozzle or flange
- Fuel type and expected dust loading
- Required output signals and power supply at site
Installation and Commissioning
Choose a location downstream of the combustion zone where the gas is well mixed, and avoid points close to air heaters, dampers or leaking inspection doors that can dilute the sample and give falsely high oxygen readings. Allow enough clearance behind the flange to withdraw the full probe length for service. After mounting, the sensor needs time to reach operating temperature before calibration. Commissioning normally includes a two-point calibration with certified test gases through the calibration port, then a check of the 4–20 mA output against the DCS or boiler control display.
Maintenance and Troubleshooting
In-situ zirconia analyzers need little routine attention, but a few checks keep readings trustworthy over long campaigns:
- Verify calibration with test gas at regular intervals and log the drift so ageing of the cell can be tracked.
- Inspect the probe filter or diffuser when response becomes sluggish, especially on dusty or heavy-fuel-oil duties.
- Check the reference air supply if readings wander without a matching change in combustion.
- Look for air in-leakage at the mounting flange if readings stay unexpectedly high.
Applications in Oman and the GCC
Across Oman and the wider Gulf, AZ30 analyzers are typical on package boilers and fired heaters in refineries and petrochemical plants, heat recovery steam generators in power and desalination plants, and kilns in cement production. With fuel efficiency and emissions reporting both under closer scrutiny, reliable excess-oxygen measurement is one of the simplest ways to trim fuel use while keeping combustion safe.
