[Stoves] Fuelwood moisture and wood stove

[Crispin Pemberton-Pigott]

Dear Otto

>I have "never" heard about stoves. which can burn wet wood cleanly, apart
from boilers, may be.

There are good reasons why boilers can burn wet wood - if they are designed
to do so.

I demonstrated to Dr AD Karve a stove that was burning very damp wood at
ETHOS, perhaps 2007 - was burning very cleanly. Basically it requires
preheating the primary air. As very few stoves preheat the primary air, they
do not deal with damp fuel well.

Very dry fuel can also make a lot of condensed particulates, principally by
burning so fast that it runs out of secondary air. That is one way to
manufacture carbon nanotubes.
