Testing the flue gas composition is crucial because it helps assess combustion efficiency and identify safety issues. Evaluating flue gas allows technicians to determine how effectively a fuel is being burned and whether the system is operating efficiently. By analyzing the levels of carbon monoxide, carbon dioxide, oxygen, and other compounds, professionals can gather essential information about the combustion process.

For instance, high levels of carbon monoxide can indicate incomplete combustion, which is a safety concern since this gas is toxic. Additionally, proper levels of oxygen in the flue gases are indicative of an optimally functioning system, while deviations can signal issues such as blockages or improper air-to-fuel ratios. Effective combustion not only maximizes energy efficiency but also minimizes harmful emissions, making this testing critical for both safety and environmental compliance.
