There is no magic 'genie' in looking for solutions for fuel-burning generation of air pollution.

You've just spent a lot of time and effort making a case for "The key to the efficiency of the heat-scavenging system is that it uses propane vapour rather than steam to turn a turbine".

Propane vapor is extremely dangerous. There are 602 Google hits on the phrase, "boiling liquid expanding vapor explosion" (or BLEVE).

Consider metal fatigue in the power plant you propose.

"...a catastrophic stress failure is likely. Such a failure can lead to a Boiling Liquid Expanding Vapor Explosion, or BLEVE. The effects of a BLEVE include missiles, blast and if the contained material is combustible, a fireball with extreme radiation hazard. The contained material does not have to be flammable for a BLEVE to occur. It is the pressure and rapid phase change that causes the physical damage."
