<p dir="ltr">Doc,</p>
<p dir="ltr">Thank you for the explanations.</p>
<p dir="ltr">In the same context, how would you define a gasifier stove? <br>
Someone my choose to call it a gasifier stove and not TLUD.</p>

"TLUD" is the combustion processes associated with the Migratory
Pyrolytic Front (MPF). that creates the pyrolytic gases and leaves
charcoal behind. That does not change. The other features of a
"stove device" can be and are diverse. And that is where we can
find all of the variations that you mention.<br>
<br>
If a stove COULD successfully operate with the MPF, it could be
called a TLUD stove even if it can also be operated in other ways.
<br>
<br>
But if it COULD be with the MPF, but if it is mostly NOT being used
with the MPF, calling it a TLUD gasifier stove is misleading.<br>
<br>
[Note: This same problem occurs with the "Rocket" combustion
processes which (for the purists among us) should have the
fuel-supporting shelf with air entering underneath until it comes up
near the burning tips of the inserted fuel. From my limited
following of on-going Rocket stove designs and production, the shelf
with associated tip-burning is often absent (by manufacturing or by
user removal) but the name is still Rocket stove. That is
unfortunate, in part because the Rocket advantages are absent and
should not be claimed by the different stove. I do not want the
TLUD distinctiveness to be claimed if the MPF is not an active part
of the operation of a stove that claims to be a TLUD.]<br>
<br>
Example: If you filll a TLUD-capable fuel chamber with charcoal,
there canNOT be a MPF. Why? Because there is no pyrolysis. The
fuel is ALREADY charcoal. That operation might be driving off
some volatiles that then move upward, but that is not pyrolysis. <br>
<br>
Note: TLUD is an acronym for "Top-Lit UpDraft". But the acronym
is now a distincitive name in its own right. And it is associated
with the MPF and with dry biomass fuels. If some other process has
ignition at the top and has upward moving air flows, it can have any
name you want to give it, but not the name TLUD. <br>
<br>
As a rather absurd example, if there is a "Lignin Powered Gasifier"
stove, it should not be called an LPG stove. That would be
misleading, would be false, and could probably cause some law suit
from the big business of LPG. I doubt that LPG is a registered
trademark, but misuse of those letters would cause trouble.<br>
<br>
So, please help to keep TLUD to mean things consistent with
"woodgas" and "pyrolysis" and MPF. Ify you discussing something
else, then come up with its own distinctive and non-confusing
name. <br>

The char yield is associated with some char combustion during
the time of the pyrolysis, but that is not the same as having
the char as the input fuel.<br>

<p class="MsoNormal"><span style="color:windowtext">Well I just
showed that char can be an input to a TLUD. I can burn

as a TLUD charcoal burner with a cooking plate in place of
the pot. Charcoal stoves operate much better, cleaner and
longer when operated in TLUD mode. TLUD was the standard
operating method for the POCA which is a charcoal-only
stove.
