I went to see on the site but I did not understand the principle.
The wood is heated and therefore produces vapors.
It's ok!
But it takes energy to heat this wood, if we use the wood directly and we burn it it amounts to the same ?!
or is it self maintained ?!
and well in this portable barbecue (tin) the fire is lit with a little alcohol, which spreads in the pile of twigs, if not in a pellet stove (pro version) it is an electric resistance + fan which turn it on ...
Did you see what I put in this stove? bits of twig!
heating with wood is no longer a chore like cutting trees with a chainsaw! the twigs only have to bend down to pick up this NRJ in a bar ... natural, non-radioactive
... non-polluting? false: when decomposing, dead wood emits ... CH4! What could be more natural ?
in short to come back to our sheep, all wood burning is emitting smoke, most are flammable, but poorly ... concentrated, they go up in smoke! with the secondary air technique, the wood gas does not evaporate because the flame catches up with it at the last moment; hence the better yield.
with a handful of twig / small dead wood I boiled a pot!
