Gas-fired boilers have a high safety factor and are not easy to explode. As long as the operation method is correct, it will not explode. Of course, an explosion may occur under the following special circumstances:

1, overpressure inside the boiler will cause the shell to burst.

2. The burner is not pre-purged before ignition, which will lead to deflagration (explosion) of furnace gas.

3. The boiler room gas leakage caused an explosion.
