The designation "gasifier stove" is fine. A more generic name that
certainly can include the many variations that keep being mentioned,
plus others that are even more different than what "TLUD" has stood
for since first used in 2005.<br>

"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

<p class="MsoNormal"><span style="color:windowtext">Well
I just showed that char can be an input to a TLUD. I
can burn charcoal <i>only</i> as an input fuel to a
TLUD. I have a set of cooking photos used for
promotion showing a Vesto operating 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. </span></p>
