To prevent explosions in fuel or gas boilers during ignition due to leaks, can an exhaust fan be installed in the flue system?

To prevent fuel or gas boilers from experiencing detonation during ignition due to leaks (or other reasons), which could cause harm, can an exhaust fan be installed in the flue system? The fan remains in operation to reduce potential hazards. Experts, come and discuss it! ! !
In this case, the fuel gas boiler operates under negative pressure.
Communicate with the design institute – how large will they design it for you? What model? Determined through calculation
Of course it can be added; generally, the air volume is twice that of a blower, while the air pressure is half as low.
It needs to be purged before ignition; there will be no problems. WNS features combustion at slightly positive pressure, while the SZS design allows the use of an exhaust fan to achieve slightly negative pressure or slightly positive pressure as well
Purging should be able to solve this problem, right?
A draft fan can certainly be added, but its purpose is generally to overcome resistance; in my opinion, having a draft fan actually only increases the risk of the burner going out.
