why not use a small gas engine for the belchometer
you can rig a custom exhaust in a matter of hours to fit 
a 5-10hp waterpump engine and tinker with the carb adj to test mixtures
most of these engines will run from 20-10:1 on mixture
and you cna get this control level at the carb adj screw
this would be the range we would want to look at anyways

if you need more heat in the exhaust build a double wall pipe
and heat the otehr chamber with the outpu from your propane burner
