"Stovers" - The following just in. Ron

(The remainder all from Grant)

Dear All

A number of changes and updates have recently been made to improve the
usefulness of the HEDON web page (the pages of the Household Energy
Development Organisation's Network):

1. The HEDON pages (http://www.energy.demon.nl) have been simplified to
reduce download times further. This is particularly important for people
with (slow) telephone connections to the Internet. For those without graphic
capabilities the entire website can be accessed in text mode at
http://www.energy.demon.nl/hedon/text/.
2. By selecting the relevant link on the homepage an Events Calendar can now
be accessed (in addition to that distributed in the email newsletter).
Please submit other important events that should be listed (for your
organisation or for others) using the form at the bottom of the web page or
by emailing the relevant information to hedon@energy.demon.nl. A growing
number of visitors are now using the site making this an important place to
publicise events.
3. The questionnaire developed by Dr Nigel Bruce on "methods for assessing
exposure of women and children to indoor smoke pollution in less developed
countries" has been added and can be accessed via any of the HEDON pages by
clicking on the relevant link. The form can be filled in online or
downloaded in Rich Text Format so that you can fill it in and return it by
email, fax or post.
4. A "What's new on the HEDON website?" page has been added so that visitors
can get a quick summary of the latest developments.
5. The Internet links page will shortly be updated... do you perhaps have a
URL to include in any of the the relevant fields... health, technical
development, renewable energy, buildings and kitchens, cottage industry,
forestry, or policy and planning? Let us know... email it to
hedon@energy.demon.nl or fill in the form on the 'Links' page.

Sending attachments with emails through the email list (hedon@onelist.com)
has been disabled. This will ensure that members with slow Internet
connections are not burdened with long (unsolicited) downloads (although
this hasn't happened up to now). In addition this is a precautionary measure
as a result of the increasing risks of viruses being distributed unknowingly
and automatically by email. From now on emails sent with attachments will be
stripped and forwarded as text only. If you would like to distribute a file
to everyone on the list please send it to me and I will make it available to
download from the website. If files absolutely have to be emailed to the
group please let me know and I will arrange it and verify that the
attachment is safe.

I hope that these changes will further add to the usefulness of the HEDON
resource. Let us know what you think and how HEDON can serve you better. Is
there something extra you would value?

With best wishes
Grant

Message-ID: <b08fe196.24dc2fe5@cs.com>

Dear Ron, Tom et al:

I wish I could work on stove full time, but I'm working full time on a 25 kW
"modular biomass" project. Which does the world need more.

Specifically, in inverted downdraft (top down) burning I have successfully
operated up to 30% moisture (made by oven drying fuel, then adding water in a
bag and equilibrating).

HOWEVER, the production of charcoal goes from 20-30% at 0 moisture content
to nearly 0% charcoal at 30% moisture. Why?

As the pyrolysis flame proceeds down looking for the rising air, it needs to
ignite each successive layer. If the next layer is very dry, it ignites
easily and the flame passes on to the next layer. If it is wet, some of the
charcoal must be burned to dry the next layer sufficiently to allow flame
propogation. This explanation is sensible and seems to fit the experiments.

I hope soon to have some more practical material to send Alex for web page on
Turbo stove.

Regards to all, TOM REED BEF

Just to add to your explanation:

I think that part of the explanation is that the steam being generated from
moisture emerging into the flame from wet wood at the rate of 27 cubic feet/1 lb
at 100 deg C tends to extinguish it, causing some of the inflammable pyrolysis
gases to be lost with the steam emerging from the flue so that, as you say, some
or even all of the charcoal is burnt so all you're left with for your efforts is
a small heap of dry ash!

If I wanted to improve the efficiency of a traditional charcoal burning operation
I would arrange for the hot outlet gases to pass through my next charge of wood
to pre-dry it or increase its dryness before using it.

Good luck!

If anyone is interested in this job, it would be my pleasure to share my
knowledge of the organization and its Board members; several of whom I know.
I am also familiar with Sacramento.

Subject: OIL ARMAGEDDON
Message-ID: <1ae0de20.24dedc6c@cs.com>

Dear CREST friends and Petroholics:

While there have been many false warnings about oil depletion in the world,
we all recognize that there is a finite quantity of oil in the ground and
that eventually the demand will overtake the supply. M. King Hubbert
correctly predicted 10 years in advance when US oil production would peak
(1973) from his criterion of Bbl oil/ft drilled.

The M. King Hubbert center at the Colorado School of Mines
(http:/hubbert.mines.edu) makes it their business to keep track of the most
responsible estimates of remaining oil . In their latest newsletter, J. F.
(Buzz) Ivanhoe summarizes world oil supplies as follows:

FORESEEABLE PERMANENT GLOBAL CRUDE OIL SHORTAGE

A critical date for U.S. and global oil consumption will be when the world's
oil demand exceeds the global supply. This watershed will occur when the
world's oil production reaches the "Hubbert Peak", i.e. when the world's oil
is HALF GONE - NOT when all the earth's oil has been consumed. The question
is NOT WHETHER, but WHEN this foreseeable event will occur.

Current estimates of when the Hubbert Peak will occur range from year 2005 by
the most bearish to 2020 for more bullish petroleum geologists. The
potential for economic dislocations and societal upheaval is enormous and
frightening. Serious planning by all governments for the foreseeable energy
crisis should be started immediately.

~~~~~~
I Talked to Buzz Ivanhoe today. He is Hubbert's heir apparent in oil
reserve prediction, having spent a lifetime exploring for oil. He can be
reached at 805-646-8620 >805 646 5506FX. Or mail to 1217 Gregory St., Ojai,
CA 93012-3038. (No Email please). Visit the web page (above) and place your
bets.

Some of us are seeking viable alternatives for our current oil based world.
Better get cracking....

Dear Tom Stubbing et al:

Hmmm. Maybe so, BUT the stove seemed to burn as well at 30% moisture as at
0% so no unburned gases that I could tell.

Incidentally, I also tried coal and it burned better than any other fuel for
length of burn. No smell of sulfur (Western coal is low).

Purists will turn thumbs down on coal, but health and tree advocates will
recognize that in some instances coal will be the fuel of choice. We just
have to see how it plays out.

Yours truly, TOM REED BEF

I introduced myself to the group a while back and had hoped to get some
feedback on my CHRBO stove. Elsen Karstad and Alex English are testing
the stove at this time and Elsens early conclusions were very favorable
from the standpoint of efficiency and ease of use. I was hoping to have
the opinions of some of the rest of you involved in developing an
efficient stove.. My stove is the product of almost 15 years of trial
and error and all the bugs have been worked out at this time. My
original design did not collapse and was not easy to tote around because
of that. The key to the new stove is its versatility, efficiency and
durability. I really would love to hear some comments. Visit my web
site at "http://www.chrbo.com".

Looking forward to your comments

Elsen: Very sorry to hear about the accident. I leave tomorrow for a week
trip to see my son and first addition to his family (our fourth

instructor-level hang-glider (I know there is a difference from
para-gliding - but from my vantage point they look equally daunting).
Since you have time to answer such frivolous questions - tell us more about
how and why this happened. What lessons for the paragliding community?
Was it difficult to get you out after the accident? Need a helicopter?
Good deal of pain - other injuries, etc? Anyway - sorry to hear about
this. Twelve days says this was darn serious. Same Nairobi hospital you
took me to? Is there anything any of us can do to help?

Look forward to more data anyway. Good luck. Ron

Subject: Fine particle respiratory fluid dynamics.
Message-ID: <199908181145.HAA15604@adan.kingston.net>

Dear Stovers,
I came across this news item which some of you may find interesting.

The following was copied from
http://www.cnn.com/NATURE/9908/17/particles.enn/

Tiny particles of air pollutants can zoom through human lungs up to
two times faster than previously thought and pose a risk to healthy
adults, according to a university scientist. "Smog kills," said
Anthony S. Wexler, a professor of mechanical engineering at the
University of Delaware, "perhaps partly because pollutant particles
are so deeply deposited in our airways."

A study conducted by Wexler and colleague Ramesh Sarangapani shows how
pollutant particles smaller than 2.5 micrometers - a size identified
by the Environmental Protection Agency as hazardous - penetrate
buildings and people's airways.

Pollutant particles are found in car exhaust, power-plant emissions
and the smoke from fireplaces and wood stoves. Clusters of the
particles produce clouds of dust, haze and smog. "Tens of thousands of
elderly people die prematurely each year from exposure to ambient
levels of fine particles," according to EPA.

In a paper to be published in the Journal of Aerosol Science, the
scientists explain how particles penetrate human airways through
dispersion and expansion resulting from contact with moisture.

"As people breathe," said Wexler, "a clump of fine particles called a
bolus will rapidly disperse throughout the lungs. At the terminal
alveoli - little sacks at the end of each respiratory branch where
oxygen and carbon dioxide trade places with blood - these particles
take up water and expand, much like a sponge, because of hydroscopic
effects."

Mathematical models of these physical events suggest that "the
smallest particles can sometimes penetrate almost two times farther
into airways than we had suspected," said Wexler.

That's because air in the center of a lung tube flows faster than the
surrounding stream, he said. And, particle-laden air mixes with clean
air at each intersection of the respiratory branches. All that
secondary mixing "dramatically speeds the movement of these fine
particles through the respiratory system," he said.

The next step, Sarangapani said, is to further investigate why fine
particles can be toxic in the lungs. "With the current amount of
knowledge available to us," he said, "I think that the EPA's current
standards are a reasonable response. But, additional research is
needed to identify the precise mechanisms involved in particulate
toxicity."

Bioenergy List Members

I would like to meet with the Bioenergy List moderators and anyone else
interested in helping manage these lists in Oakland during the Biomass
Conference of the Americas. While the schedule may be quite full an
informal meeting would be quite useful.

Please send me private email if you expect to attend the conference and
would like to discuss the lists. Please also suggest a time. One of the
lunch periods might be appropriate.

While these lists are hosted at CREST they are supported by sponsors and
volunteer moderators. As always we need volunteer moderators to share the
load, especially for the bioenergy, bioconversion and digestion lists.

Thanks,

Tom Miles

Subject: La Lorena
Message-ID: <000901beea0a$2eae4ce0$400e66d1@default>

Dear Mr. Ortiz,

Consultants from Aprovecho helped to design the original Lorena stove.
Aprovecho published the book describing how to build the Lorena. Follow up
studies, however, showed that the original Lorena had two major problems.
The combustion chamber was uninsulated and badly shaped which cooled the
fire, producing smoke. As well, the heavy stove body absorbed heat that
could have helped to cook food. Heat transfer to the pot was not optimal.

We do not recommend building the original Lorena, it needed several
modifications. Aprovecho sells a manual ( for $6) describing stoves built
this year in Honduras that look like the Lorena but produce less smoke and
are more fuel efficient. These stoves use wood ash as insulation and are
designed to assist more complete heat transfer to the pots.

Lorena itself is a wonderful material. With a few simple modifications, the
Lorena becomes a more fuel efficient and smoke free cookstove, just insulate
around the combustion chamber and heat flow path and expose as much of the
pot as possible to the high grade heat. These two design principles work in
most stoves. We also add a short 10" insulated chimney above the combustion
chamber to assist fierce hot burns and to achieve a good amount of secondary
combustion in the chimney section.

Best Regards,

Dean Still

Message-ID: <19990826095841.26087.qmail@hotmail.com>

We at IIT,Delhi are working on modelling the processes in an annular
sawdust stove.The processes identified for modelling are
1) chemical kinetics
2) heat transfer inside the sawdust bed
3) pyrolysis
4) flow of volatiles inside the sawdust bed
5) combustion of volatiles

Finally we plan to combine all the models together so as to obtain a
complete theoretical model for sawdust stoves.

Geometry chosen : Annular

Present state of work : Model for pyrolysis in an annular sawdust bed
assuming first order kinetics and conduction as heat transfer mode inside
the sawdust bed is in final stage of completion. The experimental data for
validating the model is being fine tuned. First set of resuls from
experiments as well as model are expected soon.

Feedback , questions , comments on the work summarized above are welcome.

Sir,
I visited your site. I saw for the first time a stove which is foldable.
I have few queries regarding your stove.

1) did you went about designing the stove purely experimentally or you did
some (or rigorous) theoretical analysis to come to final dimensions of the
stove ? could you please brief on this ?

2) how about changing the fuel in the stove ? say if you try with powdery
biomass like SAWDUST.

Stovers: I know there are several users of CO monitors on the list.
Perhaps others have some ideas for Kevin - a non-list member.

Kevin: Our list would not normally get into such topics, but I believe it
would be helpful to re-raise this issue - which is important for stove
optimization.

There are many commercial low cost CO monitors and display units on
the market here in the US. Could you explain the term "GCSE"? What is
your purpose in tackling this problem?

I am told that some computer-controlled auto ignition systems
operate on CO content in the exhaust. The monitor itself is probably very
cheap - and probably quite well developed.

I hope you will keep us informed on what you learn.

Stovers: The follwoing is a bulk ad - that I thought twice about sending

However, "ceramic glass" might already be or could become a useful

this product has revolutionized US stove designs. The produce is much
stronger than regular glass and provides an optical tranmissivity much
higher than that for ordinary ceramics.

to: "M.V.OZERMAN" Would you please supply us a little bit more on the
circumstances when you believe ceramic glass would be appropriate for lower
cost cook stoves. Our list is well aware of the advantages of supplying
some illumination from a stove - and that this need is usually not met with
"improved" cook stoves. My question relates to the need to keep costs very
low, to have a good lifetime, and to have the units be amenable to local
installation and replacement.

What are the smallest "panes" available? At what cost? (for
various levels of supply).

Our list would benefit from having detailed technical and cost
information. To your knowledge, What is the success of these units in
lower cost stoves designed for use by low-income families?

I'm not positive, but believe that cars use O2 sensors for the exhaust,
based on a zirconium chemical cell. Some of them have a heating element,
others don't.

I'm aware of a couple of CO sensor technologies, and I'm sure there are others.

The older home CO sensors used a tin oxide based sensor that was
periodically heated to take a reading. Not sure what the new ones use - the
only reliable ones are the "Nighthawk" brand. I got a battery powered one
with an LCD readout down to 10 ppm for about $30 US - they are available at
Home Depot, Walmart.

Our portable TESTO flue gas analyzer uses a very expensive chemical cell
containing sulphuric acid. The sensor lasts for about 2 years. It reads
from 1 to 4000 ppm and is +/- 20 ppm to 400 ppm and +/- 5% above that.

The 10 year old automotive 4 gas analyzer at our lab uses an infrared bench
to measure CO, and is quite accurate and reliable. It uses the principle
that CO (and CO2) selectively absorb certain wavelengths in the infrared
spectrum. It would be great if there was a cheap IR laser, like the diodes
used in CD players, or perhaps remote controls, that could be used in
combination with a photocell to build a cheap CO meter.

Coincidentally, I'm just off to my supplier in Montreal to pick up a bulk
order of "Robax" ceramic glass, manufactured by Schott Technical Glass
products, in Germany. Minimum order for wholesale pricing is 5 sheets,
which measure 34.75" x 60.675" each. Price just went up 20%, and is $320CDN
per sheet, about $208 US. We generate a lot of offcuts, about 17" x 5", if
they are of any use to anybody.
