Gas pressure abnormal (too high or too low) will have a significant impact on the working state of the burner, and even cause safety risks or equipment damage. The following is a specific analysis and possible consequences:

1.Hazards of Excessive Gas Pressure

-Abnormal flame morphology:

Elevated pressure accelerates gas injection velocity, potentially causing "fire escape" (flame detachment from burner) or forming excessively long flames that lead to incomplete combustion and generation of harmful gases like CO.

-Equipment damage risk:

High-pressure surges may impact internal burner components, damaging nozzles, ignition electrodes, or gas valves, thereby shortening equipment lifespan.

-Temperature instability:

Sudden flame temperature spikes could damage furnace linings or heat workpieces, compromising production quality.

2.Hazards of Low Gas Pressure

-Ignition Risk:

Insufficient gas flow may cause the flame to backflow into the burner or fuel line, potentially triggering deflagration or explosion (particularly dangerous for premixed burners).

-Unstable Combustion:

Flames may flicker, extinguish, or produce "yellow fire" (incomplete combustion with black smoke), leading to reduced thermal efficiency and increased energy consumption.

-Production Interruption:

Insufficient temperature in industrial furnaces may cause production halts, requiring frequent restarts that compromise operational efficiency.

3.System Chain Reaction

-Safety Device Activation:

Modern combustion systems typically incorporate pressure sensors that automatically shut off gas supply during anomalies. However, repeated activation may mask underlying malfunctions.

-Increased Pollutant Emissions:

Incomplete combustion releases carbon monoxide (CO), nitrogen oxides (NOx), and unburned carbon particles, violating environmental protection standards.

Response Recommendations:

1.Regular Maintenance:

Inspect pressure regulators and filters for blockages or malfunctions to maintain stable pressure levels.

2. Install Monitoring Equipment:

Equip with real-time monitoring devices such as pressure gauges and flame detectors.

3.Pressure Compatibility:

When replacing burners or adjusting gas pipelines, ensure compatibility with rated pressure specifications.

If the problem persists, it is recommended to contact a professional technician to check the gas supply system or burner design defects.
