Rolf and all,
The Windhager is not a retort and is not a TLUD at all. In a retort,
the heat is outside of the container with the fuel. And a TLUD has
TOP-LIGHTING.
It is a very nice updraft gasifier with close-coupled combustion (no
attempt to cool the gases, they are all intended for burning).

I came across this video when browsing for gasifiers.
In german language, people also call downdraft logburners gasifiers, which in
many ways is right.
The Windhager retort is a true TLUD.
The remarcable idea in this one is the double bottom sluice.
Whether it makes charcoal or not sure is only a matter of discarding earlier or
later and of the distance between the 2 discs.
(Shure a gas analyzer can tell us when it's time to let the charbed drop.)
I would air cool them, though. I have a lot of bad experience with long term
warping of hot metal plates.
I like the idea.

Dear Bjorn,
Since char is one of the better ways to sequester carbon, it should be
easy to persuade German legislators to accept it into landfills at no cost.

Paul,
since I am German, I understood the video, of course.
The system is designed for hot water production for domestic and commercial
space heating. Power range is 7...60 kW. There is no charcoal production. This
unit burns the wood and the ash is disposed. According to European standards
ash for disposal may not contain more than 5% of combustibles (char), otherwise
it cannot be used for landfill.

Betreff: Re: [Gasification] Getting both heat and char . chip boiler with
down-up gasification !
List,
I do not understand German, so I only saw the video. What is the price
tag? And what is the thermal output? And what is the quantity (char
weight percentage of input fuel)?

Hi Paul and Rolf,
Pyrolytic gas can be quite wet so precise temperatures are risky to
quote. What I can tell you from experience, is that it always burns
hotter than clean producer gas, upwards of 1,050C, a basic tar test
for cleaner specification gas, 13-1500C is a rough rule of thumb for
gas exiting the combustion chamber. It has a very high radiation
factor useful for refractory application, but the price for this is
that you will get a high ash content in the kiln and flue dust emissions.
The actual combustion is complex, but achievable in a non regulated
situation, emissions being the issue, both dust and toxic gas CO,CH4,
and Dioxins. Combustion of these gases have been our focus for some
6-7 years, and current work at CalForest in California, is to use
this gas to dry the incoming fuel to the charmaker.
Might be able to offer more later as you develop the concept.

Rolf,
I am responding to your two messages that are repeated below.
I am definitely with you on this matter of making heat AND making
char. I have lots of experience with small scale devices, and
moderate experience up to 200 kW thermal.
Yes, BOTH the heat and the char are important, and help to pay for
the other one.
Before taking the discussion off-list, could you please tell all of us
about your needs and about your resources. No solution is free from
the development costs. Does the kiln already exist (or is that
another cost to be covered?) And we want to find out who else has a
"burning" interest in this. (This was 2/3rds of a pun. 2/3rds
is P U ; as in pew!!) (With full respect for the non-native
English speakers on this listserv, here is then meaning of the joke:
Wordwizard • View topic - *PEW* !! whats that??
<http://www.wordwizard.com/phpbb3/viewtopic.php?p=63421>
http://www.wordwizard.com/phpbb3/viewtopic.php?p=63421 mj (a.k.a.
Michael), The word *PEW*! has been around a bit more than decades (
see ... 2) [1859] Expressing disgust at an unpleasant *smell*.
And where it happens does make a difference, such as with labor costs.
You are in Mexico. In what part? Plenty of dry biomass?? Please
send info. Okay if in Spanish (I can read that, and if others
cannot, we will cross that bridge when necessary).
Do you know Noel C. of forestry in Mexico? Could this become a
Mexico project?
Question for everyone: When "woodgas" (pyrolytic gases) come off of
the biomass, what is the highest temperatures at which they can be
burned? That would be with stochiometric combustion, right? Just the
right amount of air.
Paul
