Many thanks for the analysis Howard. Your numbers and description of consequences convinces me. I hope no-one thinks that my suggestion that "the potential violence of model boiler explosions is overrated" is any reason to believe that small boilers are safe!
My comment was partly due to something overheard at the Bristol exhibition. A chap was telling a friend that a small traction engine happily steaming away was nothing but a bomb on wheels. That I doubt, at least compared with a actual bomb of the same size.
Consider what Wikipedia has to say about Nitroglycerin: "Detonation of nitroglycerin generates gases that would occupy more than 1,200 times the original volume at ordinary room temperature and pressure. The heat liberated raises the temperature to about 5,000 °C" And the same source gives the detonation velocity as 7700 m/s. That's a lot of energy released almost instantly.
So there you have it: conclusive proof that filling a steam boiler with Nitroglycerin is far more dangerous than filling it with water! I claim today's prize for stating the bleeding obvious...
Neil's link about full size boiler explosions is interesting as is this one too.
I've never heard of a serious accident involving a model steam boiler. That inspires confidence in their build quality, maintenance and responsible operation.
