You would be better off making a small steam engine and burning your

Hmm...that IS a thought actually..and an electric fan once it gets going
to 'turbocharge' the boiler..

You don't even need that - just a good chimney and steam injectors to
give it a bit of a push.

A 250psi boiler full of superheated steam (at a few 100C) is a different
"kettle" of fish to manage though...
