Peter has posted to us about his downdraught barbecue stove so I think
you are right. Also when Elsen was making his chardust he used just
such an approach as a pyrolyser and flare.

The thing that strikes me about both down draught and top lit
updraught (alias inverted down draught o.k. Martin ;-)) is that the
incoming air keeps the mass of fuel outside the active zone cool, so
this limits how much fuel is undergoing reaction at any one moment
without the need to add fuel in Paul's trickle feed fashion.
