What is the primary cause of most infrared burner failures?

Excessive gas pressure or overheating of the burner box is the primary cause of most infrared burner failures. When a burner is subjected to high gas pressure, it can lead to overheating, which may cause damage to the burner components, including melting or warping the burner material. Infrared burners are particularly sensitive to these conditions because they operate at high temperatures, and any excess pressure can result in combustion instability or mechanical failures. Proper regulation of gas pressure is crucial to ensure safe and efficient operation, as well as to extend the lifespan of the burner.

Incorrect gas type, insufficient gas flow, and faulty ignition systems can certainly lead to problems with burners, but they do not account for the majority of failures. Using the correct gas type is essential for compatibility, while insufficient gas flow can affect performance but is typically controllable through proper installation and maintenance. A faulty ignition system can disrupt the lighting process, but it does not usually lead to the catastrophic failures seen with excessive pressure and overheating. Understanding the parameters that lead to burner failure helps technicians not only in diagnosis but also in prevention through proper equipment handling and maintenance practices.
