What does a combustion analyzer measure in building performance testing?

A combustion analyzer is specifically designed to measure the content of flue gases, which is essential in evaluating the efficiency and safety of combustion appliances like furnaces, boilers, and water heaters. By analyzing the flue gases, the device can determine the amount of oxygen, carbon dioxide, carbon monoxide, and other gases present in the exhaust. This information allows professionals to identify how well a combustion appliance is operating and whether it is burning fuel efficiently and safely.

This focus on flue gas composition is crucial because improper combustion can lead to increased emissions and potential safety hazards, such as carbon monoxide leaks. By understanding the combustion process through flue gas measurement, technicians can make informed decisions about necessary adjustments or replacements needed for optimal performance and safety in building systems.
