In neither of the two quote you gave was gasifier mentioned, I suspect
both Crispin and (I know) myself deliberately avoided the term. Tom
Reed has posted a very likely reason why people are happy their
devices be termed gasifiers.

This is how the idd stove "works", an ordinary updraught stove behaves
similarly. The idd better controls the offgas production and enables a
better match with secondary air.

I very much doubt this under natural draught with no chimney.

I have honoured your xpost this time, I consider it a stoves related
matter.

I was giving Tom Reed first refusal :-)
