Burner FAQ — Combustion Troubleshooting

Ignition difficulty means the burner cannot ignite at startup. Possible causes include power failure, damaged ignition electrodes, or fuel-supply problems. Check the power connection, replace the ignition electrode, and clean the fuel pipeline.

Incomplete combustion lowers thermal efficiency and pollutes the environment. Common causes are insufficient fuel supply, too much or too little air, and carbon buildup in the combustion chamber. Adjust the fuel supply, balance the air flow, and clean the combustion chamber.

Unstable combustion reduces work efficiency and can damage equipment. Causes include poor fuel quality, carbon buildup in the chamber, and ignition-system malfunction. Use higher-quality fuel, clean the combustion chamber, and service the ignition system.

Smoke above the standard signals environmental and safety risk. It usually comes from incomplete fuel combustion or a high combustion-chamber temperature. Adjust the combustion parameters, clean the combustion chamber, and replace the filter screen.

When the burner cannot hold the chamber temperature, the equipment may overheat or run too cold. Causes include a faulty temperature sensor or a malfunctioning control system. Replace the temperature sensor and maintain the control system.
