The whole boiler idea is a bad one. They store substantial amounts
of energy,and even a small one would destroy the average garage,
not to mention anyone standing nearby.

All this talk about boilers is why I decided not to make a steam
engine. The boilers just require too much vigilance. Which I'm not
prepared to be. Vigilant, that is.

Just have to respect what can happen. Afterall, folks are killed
by water heaters when safeties fail.

Why not look into flash boilers. The tubes don't store as much
energy to be converted into a bomb should things go badly.
If you are stuck on using that old propane tank, just cut it and
line it with brick for the combustion chamber. Just don't
use it for a pressure vessel.
How much steam did your planned engine require?
