Dear Martin and all,
Regardless of any naming, you have expressed (I believe) the issue of
the fire ( and air) coming up through the bed of the fire. Such a
fire can exist if there is a grate under the bed of embers and fuel.
But if the fire is on the ground, it seems like the access to the air
(the necessary oxygen) is conical (point is upward) and on the outside.
Whatever is in the center at the bottom is actually shielded from
access to the air if the fuel pile is sufficiently large or
sufficiently "closed" (meaning, no large log present to allow a
channel of air to get down and into the center of the fire.).
We all talk of the 3-stone fire as if it was one type only. But the
placement of the fuel wood and sizes could greatly impact the
important issues of cook-fires (duration, emissions, etc.). This
might have been studied in the past. It is not on my list of topics
for research. Maybe someone else will follow up.

Quoting "Boll, Martin Dr." <[email protected]>:
Dears,
Paul (Dr. TLUD), Paal, Andrew and all,
Some days ago Andrew made us look to the rocket-stove as a type
of stove, which is derived from three-stone fire; e.g. the rocket-stove is
only fed from one side.
Andrew, I didn't answer yet to that. I like this generalizing angle of view!
It gave me new aspects to see stoves.
Paal, as I am interpreting you right, you see TLUD as a typical manner of
burning.
Paul, you are without doubt Dr. TLUD! You have the merits for that (mostly
in batch-load-mode running) stoves. And without your concentrated direction
to and work on that TLUD-stoves, the stoves-community was certainly not so
successful focussed to that, even myself. And I find, it is a good
direction.
So I am thinking for a long time about TLUD and TLUDs.
Since long time In my mind I see the stone-age ancestors sitting near their
Fire-TV looking their interesting and exciting program. Playing along with
that, they certainly once pushed a stick under the glowing charcoal. That
TV-program was possibly the first through fire-bed burning, and possibly
most exciting for our ancestor, because it made a flame without nasty smoke.
And I am sure he re-made this with intention. Possibly they called it
smoke-free-fire in their language.
Naturally he did not start his fire as top-lit, because he would not have
succeeded. But he had a "through-fire-bed-burning", or more scientific
sounding a _per-fire-bed-burning_.
And as English-speakers like to make a word out of abbreviations I would
propose to call that: PeFiBe- burning.
In my opinion this contains that the essential foundation, what we expect
by a TLUD.
But there are other interesting PeFiBe-stoves, you all know; mainly
different in the grade of deflection of the vertical direction;
even I know an interesting stove run in sky to earth direction (forgive this
expression, it is only to de-connect from top and bottom of the fire)
I propose: let the TLUD-stove be a TLUD-stove. But let us speak about
PiFiBe-burning, or let us find another new term expressing this
burning-type, that all those interesting stoves are conform in.
We don't want to fight about words, but to have fun together with good
performing stoves.
-A lonely log doesn't like to burn-
Regards
Martin
