How to deal with backfire during boiler burner combustion?
We all know that in the later stages of use, boiler burners often encounter various problems and malfunctions due to delayed maintenance or component wear. At this time, we need to have the ability to troubleshoot and solve problems. Below, we will learn about another type of fault problem, which is how to deal with backfire during boiler burner combustion?
Tempering is a phenomenon in which the flame shrinks back to the head of the burner through the flame hole during gas combustion and burns at the nozzle of the mixing tube. When the flame burns, there is a lot of noise, the flame becomes shorter, and the inner and outer cones are not clear. Tempering disrupts normal combustion, rendering the heat unusable and instead damaging the stove, leading to accidents. When tempering occurs, the stove valve should be immediately closed, the cause should be identified, and appropriate measures should be taken.
The reasons and solutions are:
1. If the burner or nozzle is clogged with dirt and causes backfire, it needs to be cleaned.
2. There is air inside the newly replaced rubber hose.
3. Excessive air volume at once.
4. If the pressure in front of the stove is too low, it is also prone to backfire.
5. When the stove is ignited, the high temperature of the burner itself can also cause backfire.
