This seems very useful.
Drying out fuel is a natural use of otherwise wasted energy.
Pyrolysis is a further step.
That said, I wonder if a rocket could be used to create draft for a charcoal forge, either by heating combustion air indirectly or an under tuned rocket exhasting unburnt gases into the coal bed.
This comment was mine from the original thread last year...
I was thinking that adding the wood gas as "secondary fuel" along with a complimentary "secondary air" supply would be easy to add to the rocket (or to a batch box for that matter).
I bet this wood gas could also be added to a traditional charcoal forge firepot, but I'm having trouble seeing a rocket feeding into a charcoal forge... without burning up a grate/tuyere, or restricting the draft created with said grate or the charcoal bed.
But the charcoal production was certainly intended for fueling a traditional charcoal forge, though again, it could also be fed to the rocket instead of wood, possibly to greater heat effect?
Even incompletely charred wood in the retort would, as you say William, make for good dry fuel, which in the eyes of a charcoal-burner would be a fault in the doing... here, it's all good!
