Understanding the Role of Oxygen Analysers in Combustion Control
Oxygen analysers play a critical role in ensuring optimal combustion control across a variety of industrial processes, including power generation, manufacturing and heating systems. By accurately measuring oxygen levels in combustion systems, these instruments help to maximise efficiency, reduce emissions and ensure safety. Here, we explore the importance of oxygen analysers, how they work and their key benefits in improving combustion control.
How oxygen analysers work
These analysers are designed to measure the concentration of oxygen in combustion exhaust gases. They are typically placed within flue gas ducts or stacks, where they continuously monitor the oxygen levels in the exhaust. The measurement data provided by the analyser is then used to adjust the air-to-fuel ratio in real time, optimising combustion efficiency.
Importance of combustion control
Combustion control is vital for maintaining optimal fuel efficiency, reducing operational costs and minimising harmful emissions. Poor combustion can lead to incomplete burning of fuel, which not only wastes energy but also increases the production of pollutants such as carbon monoxide (CO) and unburned hydrocarbons.
By monitoring oxygen levels, the analysers help regulate the amount of air introduced into the combustion chamber. Too little oxygen results in incomplete combustion, while too much oxygen can lead to energy loss, as excess air carries heat away from the process. The optimal balance ensures that all the fuel is combusted while minimising wasted energy and emissions.
Key benefits of oxygen analysers

- Reduction of emissions:
- Improved process control:
- Enhanced safety:
- Extended equipment lifespan:
The analysers provide continuous feedback on oxygen levels, enabling precise adjustments to the air-to-fuel ratio. This ensures that the right amount of oxygen is supplied for complete combustion, maximising fuel efficiency. In industries, such as power plants and furnaces, this can result in significant cost savings.
Properly tuned combustion systems reduce the output of harmful emissions such as nitrogen oxides (NOx), sulphur dioxide (SO2) and carbon monoxide (CO). By using the analysers to achieve efficient combustion, industries can comply with stringent environmental regulations.
Analysers provide real-time data that allows operators to make immediate adjustments to combustion parameters. This ensures consistent process control and stability, reducing the likelihood of operational issues or fuel waste.
Monitoring oxygen levels is essential for ensuring safe combustion. Low oxygen levels can lead to incomplete combustion and the formation of dangerous gases like carbon monoxide. On the other hand, high levels of oxygen may increase the risk of overheating or even combustion explosions. Analysers provide the necessary data to maintain a safe operating environment.
Efficient combustion minimises the formation of soot, slag and other residues that can accumulate within boilers and combustion systems. By optimising the combustion process, analysers help reduce the wear and tear on equipment, extending its operational lifespan and reducing maintenance costs.
