Most likely there isn’t any water in the boiler and the flames are trying to heat water that isn’t there. In case you’re wondering this is a fire tube boiler and the flames pass thru tubes inside the water vessel. Normally this is prevented by a low water cutoff but it’s possibly clogged with mud. This thing is gonna melt
What makes them go boom is when the blower doesn’t clear the combustion chamber of gas before igniting. Most boilers in residential use these days are like tea kettles. They’re pretty safe unless the room fills with gas then ignites

Ah, so no steam no boom. That’s good
Or well not as bad as it could be at least
