Frequently Asked Questions

What gases can a flue gas analyzer detect?

They typically measure parameters such as oxygen (O2), carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx), Nitric Oxide (NO), sulfur dioxide (SO2), and sometimes other gases or particulate matter. By analysing these components, users can optimise combustion processes for efficiency, minimise emissions of pollutants, and ensure compliance with regulatory standards.

What industries commonly use flue gas analysers?

They play a vital role in industries such as heating, power generation, automotive, and environmental monitoring, helping to improve energy efficiency, reduce environmental impact and ensure appliances are safe.

What is the difference between a flue gas analyzer (FGA) and a combustion analyser?

In general, there isn't a big difference between them as they are often used interchangeably to refer to devices that measure and analyse the composition of gases produced by combustion processes. However, there can be slight differences in how these terms are used depending on context and specific applications and devices.

They generally both measure gases emitted from combustion processes, such as those from boilers, furnaces, or engines. FGA's focus on measuring parameters like oxygen, carbon dioxide, carbon monoxide, nitric oxide, nitrogen oxides, and other combustion-related gases. They are commonly used in heating, power generation, and environmental monitoring industries. Combustion analysers may offer additional features such as calculating combustion efficiency, stack draft, and performing other diagnostic functions beyond basic gas analysis.
