When heating the boiler, the boiler electric heating element will sometimes burst. If the leakage protection is not in place, accidents are likely to occur. So many people want to know why the boiler electric heater will burst, and how to make the boiler electric heating element safe?
first,let us analyse the reasons
1.Boiler heater surface scale
When boiler electric heating element heat water, they produce a chemical called calcium carbonate, known as scale.In some areas where water quality is hard, the surface of boiler heater element will be easy to form scale.
The electric heating pipe of boiler cannot transfer the heat converted from electricity in time due to the package of scale. After a long time, the surface of the heater element will burn out, and even the tube will burst.
2. Magnesium oxide powder in boiler heater is damp
When the boiler heater is made, it will be filled with magnesium oxide powder with heat conduction and insulation, but the magnesium oxide powder has moisture absorption. When the boiler heating element is placed in a humid environment for a long time, it may absorb moisture from the pipe mouth.
Or some irregular manufacturers did not dehumidify the magnesium powder in the production process or did not put the boiler heater in the oven dehumidification. At this time, the electric heating tube of the boiler is energized. The moisture in the tube will be heated and become gas. Due to the effect of thermal expansion and cold contraction, the electric heating tube of the boiler will burst open.
3. Dry burning
The boiler heater tube of the boiler heating liquid is designed in accordance with the power standard of the heating liquid, so when the heating liquid leaks out of the liquid and appears dry burning, the electric heating pipe of the boiler will also burst because the surface temperature is too high.
