[Stoves] Wood-ash as insulator

Dear François,
Are you building a metal institutional rocket stove? Where would it be used?
If yes, I guess you are following the plans on Peter Scott's website, there
are several advices for an insulation : www.rocketstove.org. Clay is a good
option.
I strongly recommend you not to use stainless steel for the combustion
chamber, nor metal. It won't last long. We saw it with our stoves, we used
conventional stainless steel. The chambers didn't last 2 months, they were
deformed and ripped-off by the fire intensity.
Stainless steel is expensive, it is even more if it is heat-resistant. I am
not sure heat-resistant does last much longer either. Stoves in institutions
are used several hours a day, sometimes almost all the time. I think strong
ceramics or bricks should be always be used in institutional stoves, not
metal. I believe others share this opinion on the list.
I think short-lasting metal combustion chamber can make sense on a 5 dollars
stove for the domestic market. So it can be easily manufactured, people can
afford it, there can be a widespread adoption. But people expect
institutional stoves, costing more than 100 $, to last longer.

Stovers:??
?? Read the information on a 65% reduction in CO2 carefully.? That is if
they ever use CCS - which I doubt will ever happen.? We need to phase in
wood (in the form of Biochar to get carbon negativity) instead.? Mississippi
can do it.

Subject: [Stoves] Lignite in Mississippi
Dear Friends
?
Energy Company Southern reports they have patented and licensed a lignite
burning power plant design that ?burns cleaner? than natural gas. It has
been licensed to China. It was developed for a Mississippi-based coal
deposit. The Boss man (CNBC interview) did not define ?cleaner?.
?
My suspicion is that it is a fuel composition-related achievement. The H2
content of the fuel must be high. It also must be a statement conditioned on
the combustion devices being defined in order to make the comparison.
?
I am happy to hear that they have done at a large scale what we have done on
a micro scale. I am willing to bet it is a combined cycle gasification mode
power plant. The increased efficiency reduces the emissions per kW output.

Crispin

Dear Ron
?
Very informative. Thanks for reporting.
?
> ?? Questions?
?
The more than 100 types of biochar:
Are they significantly different in some respects?
?? RWL:? Many respects.? pH especially?ash content? especially rice husks,
etc.?? They have used multi-variate analysis to break into four main groups
that will (among other things) predict lifetime, best application rates,
etc? (not yet ready for publication).
Does the process used to produce it make more of a difference than the
species?
?? RWL:? probably both.?
Is the consistency of the product important for making predictable
agricultural results??? ??
?? RWL:? Yes
?
That would guide the producers as to where they should put the most effort.
??? RWL:? T he pros in this area (not just Australia) a?e feeling?good about
having it worked out pretty soon.? I heard one say it is a lot like applying
different fertilizers, lime etc.? Until you have some testing, it looks
mysterious.
Ron

Thanks Ron for the summaries and for the excellent questions you always
manage to pose to speakers.
The Kansai Corporation rice husk gasifier is interesting. They feed 150
kg/hr husk at 2000 kcal/kg and get 50 kg/hr char. It is a stirred bed
gasifier. Husks gasifying in the bed at about 600C. Air is added above the
bed to burn the gases. Stack gas is 15% O2 so they use lots of excess air.
About 30% of the heat input is recovered as hot water which is used in the
bio oil process and in winter for heating.
I was interested in the labeling of the 10kg bags. They indicate 40% carbon
and 50% silica (SiO2). They also list macro elements in MG/kg.
They provide separate instructions for use in gardens, horticultural crops,
row cropland tees.
Numbers of units and actual use are still not clear. I heard that Kansai
Corp had installed 200 of these and made char from about 10% of their husk
production of 100,000 tpy. I hope the presentations will clear up the
confusion. But it is not clear when we will see presentations or written
summaries. That is why I took a lot of pictures of slides.

Miles and family and 25? others to a rice husk charring operation. At least
three from Australia including Adriana Downie. Tom took lots of pictures
(after 4 days of most slides also). This has been in operation by a city
owned recycling operation in Shiga prefecture for about 8 years. Heat
captured and used for processing canola oil for diesel operation. Char in
large bags available at (I think) 700 Yen (little less than $10) for 10 kg.
Saw production at the rate of about 1 bag each 20 minutes. We could all get
up real close ? even to touch (water-jacket cooled) char coming out.
Pyrolyzer manufactured by the Kansai company ? with about 2000 similar
around Japan (maybe handling 10% of all Japanese rice husks), with some
appreciably larger than this one. This being mentioned to emphasize long
history of commercial Biochar operations in Japanese ? whereas very recent
US GAO report has Biochar listed as meriting a ?2? on a scale of 1 to 9. I
put anything at 10% of a market at an 8 at least.

The whole process started (in '80s??) with detergent-caused algae bloom in
nearby largest lake in Japan (we could see in distance from their
observation deck ? along with mostly rice fields on all directions). The
group started manufacturing their own soap as phosphorous-based detergents
soon thereafter disappeared from the market. When better detergents
reappeared (we need some in US now) they switched to making bio-diesel.
Rice husks needed for part of still on-going biodiesel production. Hey use
both waste oil and virgin canola oil, I believe.

Stephen's job was only to give a country report for Australia. The obvious
question is how many worldwide and my guess is that we are over fifty by now
? but maybe someone like Kelpie can give a better count from IBI
perspective. This again emphasizing that the US GAO didn't do a good job

making char. I think he may have been saying so the previous day. He also

by the country's coal resources ? which we have to find a way to keep in the

yet a panacea ? but lots of interest in this first attempt worldwide to tie
Char closely to climate topics.through a commercial ad campaign. At least
4-5 talks on this topic.. Key seems to be a 20 Yen (28 cent) label that is
attached to any produce packge? with half going back to the farmers for the

Many thanks William
They note:
"With TRIGT, the IGCC facility in Kemper County will turn Mississippi
lignite into gas while cleaning emissions of sulfur dioxide, nitrogen oxides
and mercury to near natural-gas levels. It also will produce 65 percent less
carbon dioxide emissions than the current pulverized coal plants."
And I note that they are in fact using a coal gasification process and
calculating their CO2 emissions on a kW generated basis. It is a far better
system efficiency than a single step process but it certainly comes at a
cost. There was initial talk about putting one into Ulaanbaatar as they 520
MW plant is getting close to capacity. It is pretty expensive.
The inherent emissions of mercury etc are already removable. I note they are
talking at Southern of carbon capture. Perhaps someone will pay them to do
that too.

Thanks Tom for those numbers.
They are burning 150 kg/hr and getting 20 kg of carbon in the final result.
Do you have any idea what the moisture content of the feedstock is?
Do you know if the silica has any ?medicinal? benefit? There are people
putting ground rock dust on fields and forests claiming benefits so I
wondered if that was related.
Thanks
Crispin
++++++
The Kansai Corporation rice husk gasifier is interesting. They feed 150
kg/hr husk at 2000 kcal/kg and get 50 kg/hr char. It is a stirred bed
gasifier. Husks gasifying in the bed at about 600C. Air is added above the
bed to burn the gases. Stack gas is 15% O2 so they use lots of excess air.
About 30% of the heat input is recovered as hot water which is used in the
bio oil process and in winter for heating.
I was interested in the labeling of the 10kg bags. They indicate 40% carbon
and 50% silica (SiO2). They also list macro elements in MG/kg.

Subject: [Stoves] Wood-ash as insulator
Message-ID: <000001cc7692$18853e70$498fbb50$@id-ong.org>
Content-Type: text/plain; charset="iso-8859-1"
Hello everyone,
I am currently trying to build a wood saving stove (rocket stove model). All
the info I gathered are saying to use wood-ash as an insulator between the
outside layer of sheet metal and the L-shaped combustion chamber.
Do you know if I could replace wood-ash by anything else ? Something easy to
come by? Something like dry sand for instance ?
Thanks!
Fran?ois

Dear Lloyd,
The most significant type of biochar that's I've seen in Thailand has been
the use of charred rice husk (no shortage of that feedstock in Thailand!),
which has been used as long as people can remember. The largest user has
been the horticultural sector; however, I have also seen char being made
from various other agricultural waste feedstocks and there's murmuring of
the introduction of biochar cookstoves in my province (all happening at a
relatively small-scale though, but repeated a HUGE number of times).
Re. the charcoal side of things, Thailand has a fairly long history of
charcoal production from all manner of feedstocks, although the most common
today are eucalyptus, rubberwood (sometimes), bamboo (through the Japanese
influence), and another wood type that I am unable to recognise as yet (no
mangroves in my area, so I don't know the extent to which they're being
used). There is also some collection of wood smoke distillate, but the
market is still very small (read: the fertilizer and pesticides industries
are still too strong).
Karl Frogner has also been involved in some biochar production/use work in
Thailand (in collaboration with Kasetsaert University), although I don't
know the status of the project at the moment. And, looking at the agenda for
the Kyoto Biochar Conference, I also see that Kasetsaert University is
involved in more biochar work, although us "little people" have yet to
actually see anything come out.
Something that may be of interest to you is that we're in the process of
putting together a farmers network in our province and I'd like to begin
trialling rice husk biochar through it in a more targeted way (currently,
there are 3,500 farmers interested), so I hope to have some solid
data/results coming up in the next few years :) This will be done in
conjunction with various other soil amendments, growing methods, crop types,
and lab testing of soil mineral content and crop nutritional content
(depending on the health of my bank account, as this will all be self
financed until we can find a donor/sponsor), so hopefully there'll be some
good stuff in there.
Cheers,
Bryan
