<div class="moz-cite-prefix">Dear all, especially Frank and
Crispin and Tom / Erin,<br>
<br>
Gustavo has presented a very nice video of the use of a tall
TLUD gasifier under a DUAL purpose stove frame (frame = stove
structure without the heat source) that first boiled 5 liters of
water in 12 minutes, and then converted into a plancha stove
with chimney, cooking papusas (related to tortillas). Total
cooking time 1 hour 45 minutes on one batch of wood chips/chunks
(5237 grams) that yielded 1300 g of char. 25% weight yield of
char. Probably could have operated an additional 10 minutes
with pyrolysis fire and a slightly lower percentage yield of
char.<br>
<br>
You who are on the Biochar and on the Stoves Listservs have not
seen this 10 minute mp4 video because it is 9.4 MB. I am sure
that Tom and Erin will make it available via the Websites and
send the link. And I will try to have it soon of <a
moz-do-not-send="true" class="moz-txt-link-abbreviated"
href="http://www.drtlud.com">www.drtlud.com</a><br>
<br>
Note: That is approximately 4000 g of fuel of pyrolytic gases
(including moisture content that was probably near 15%). Any
ash content (probably 1% of the raw fuel) remained in the char.<br>
<br>
With the above information, the folks who are strong with number
(Crispin, Frank, Tom and others) can calculate many important
values such as <br>
<br>
A. energy released [[ I think it is about 10 to 12 MJ per
kg of gases, so that is about 40 to 48 MJ released, with about
16 to 30 MJ of energy remaining in the char. This relates to a
side discussion about the value / amount of the energy in the
gases vs. in the char when TLUD stoves operate to completion of
a batch of fuel (so there is no need to separate out any
un-pyrolyzed fuel). MANY variables, so the numbers are still
quite approximate. ]]<br>
<br>
B. average fire power over the time of the batch: Using 44 MJ
released in 1.75 hours, that is 25 MJ per hour, which is a 7 kW
fire. That matches well with the 12 minutes to boil 5 liters.<br>
<br>
Sorry if you have not seen the video yet, but it will be
available via websites as soon as possible.<br>
<br>
Gustavo, WELL DONE for this initial experience. This all bodes
well for the future of TLUD thermal power into so many types of
plancha stoves. <br>
<br>
Paul<br>

only now I found the way to send you a good video. We can
