Oxygen Analyzer for Hydrogen Boiler Exhaust Gas – Precision Monitoring for Clean Energy
Reliable control of oxygen content in hydrogen boiler exhaust is critical for efficiency, safety, and emissions compliance. Our oxygen analyzer for hydrogen boiler exhaust gas delivers real‑time, high‑accuracy measurements that enable operators to optimise combustion, extend catalyst life and meet stringent environmental standards. Designed for continuous operation in harsh plant environments, the instrument combines robust hardware with intuitive software, making it the preferred choice for power plants, petrochemical complexes and industrial hydrogen generators.
How It Works – Advanced Optical Sensing
The analyzer employs a tunable diode laser absorption spectroscopy (TDLAS) head tuned to the 760 nm O₂ absorption line. A sealed optical path eliminates contamination, while a temperature‑controlled housing maintains measurement stability from –20 °C to +60 °C. The laser light passes through a quartz sample cell; absorbed intensity is converted to an oxygen concentration via built‑in calibration algorithms. Data are output to a PLC or SCADA system through Modbus‑TCP, Profibus or 4‑20 mA, ensuring seamless integration with existing control loops.
Continuous self‑diagnostics monitor laser power, detector health and cell pressure, triggering alarms if any parameter drifts outside preset limits. This proactive approach reduces downtime and guarantees that the oxygen signal remains trustworthy throughout the plant’s operating cycle.

Application Scenarios
- Hydrogen‑fired steam generators where excess oxygen reduces turbine inlet temperature and fuels inefficiency.
- Industrial hydrogen production units (electrolysis or steam‑methane reforming) that recycle boiler exhaust to pre‑heat feed streams.
- Zero‑emission power plants requiring continuous verification of low‑NOx combustion achieved through precise O₂ control.
- Process‑intensive refineries that blend hydrogen with natural gas; monitoring exhaust O₂ helps maintain catalyst integrity.
FAQ
What is the minimum order quantity (MOQ) for this analyzer?
We accept orders from a single unit for prototype or pilot projects. For bulk purchases, a standard MOQ of 10 units applies, allowing us to optimise packaging and reduce freight costs.
Can the device be customised for specific exhaust gas compositions?
Yes. Our engineering team can adjust the optical path length, add corrosion‑resistant coatings, or integrate additional gas‑type compensation algorithms to match the exact matrix of your hydrogen boiler exhaust.
What is the typical lead time?
Standard configurations are shipped within 15‑30 days after order confirmation. Customised builds require 45‑60 days, depending on the complexity of the requested modifications.
Is there a warranty or service agreement?
All units come with a 24‑month limited warranty covering parts and labor. Extended service contracts and on‑site calibration support are available on request.
