How is the noise generated by the burner in a heating furnace?
Thread Content
The burner in the gas-fired heater inside the device always produces some harsh noises while burning. I would like to ask the experts: what causes the noise from the burner?
After lighting the lighter, listen carefully – there is a very slight burning sound. For the same reason, the combustion reaction between the gas and air ejected at high speed from the burner generates light and heat; friction with the gases inside the furnace also produces noise. Jet planes are noisier than this, right?

This is the sound produced by the friction between the airflow and the metal
The noises generated by the combustion in the heating furnace nozzles can be categorized as follows: 1. Noise is produced when the gas composition becomes lighter and more gas is consumed, or when preignition occurs during combustion; this noise is mainly caused by the friction between high-speed air currents and the nozzles； 2. The noise generated when the nozzle is blocked is mainly caused by the vibrations resulting from detonations due to poor airflow out of the nozzle; at this time, backflow occurs in the nozzle and the flame burns in a flickering manner ； 3. The connections formed by the burners are loose or damaged, causing increased airflow vibration and resulting in noise.
It is the sound produced by high-speed expulsion of gas
It is the sound generated by significant friction resulting from the change in the nozzle diameter, as gas or steam flows at high speed through the gun nozzle.
Check whether there is oil in the gas; the presence of oil can also cause abnormal noises
Vibration, including possible resonance, can also generate a lot of noise. .
This should be closely related to the gas velocity; it has been observed before that the higher the gas velocity, the greater the noise
