What is the cause of deflagration of the burner during ignition

The burner is a burning device that we often use on industrial kilns. We use it in many places. It allows us to carry out industrial manufacturing. Compared with other auxiliary combustion devices, the burner is very important. When we use the burner, we need to ignite. Sometimes, deflagration occurs. So, what causes this? Now, let's take a look.

What is the cause of deflagration of the burner during ignition

1. In the ignition process of the burner, due to the relatively closed ignition space, once there is gas residue, deflagration is easy to occur during ignition, which may cause damage to the burner body, or personal accidents. If we want to solve the deflagration problem, we usually need to purge the radiant tube in advance and then ignite it. However, in the application of pulse controlled burners, due to the frequent opening and closing, purging in advance will take a certain time and cannot achieve accurate control.

2. We need a certain amount of leakage when the control valve of the air pipeline is closed, and it can also be adjusted. Usually, the electromagnetic butterfly valve is common on large diameter pipelines. It can realize the adjustment of large and small flow, and requires flange clamp installation.

3. On the small diameter pipeline, the air solenoid valve has obvious advantages over the electromagnetic butterfly valve due to its convenient installation and low price. It can be used in the air to realize the dual regulation of large and small fire flow.

After the introduction above, I believe you have known the cause of deflagration of the burner during ignition and what the solution is.
