[Stoves] Major case study about TLUD stoves

I could imagine a Sankey diagram for a stove with variable qualities of
fuel, environment, and pots on top could end up being quite complex, but it
could be a great way to visualise the impact of various 'key' parameters
and features, especially if it looks at more than just the stove and fuel
but includes the growing, collecting, preparing, using and maintaining and
replacing of the fuel.
If anyone had even a stab at compiling such a chart it would be great to
have as a reference or discussion document.
Please do post something if you have tried.
This report from India is excellent, many thanks for sharing.

Alex that is a great idea.
I have wondered for years if this was going to make it to market and
prepared a little for it. I have a proposed method for calculation the
performance of a pair of stoves using the fuel in a chain.
The implementation is the substitution of charcoal for coke which is
perfectly sound from a manufacturing point of view. A lot of the Eastern
USA forests were made into charcoal for steel production. It is not
everywhere this setup can work.
A faint glimmer shone in Tajikistan last week when it became clear that
one of the fuels available is a high energy coal with enough volatiles to
light easily. In a TLUD if burns off the volatiles and goes out, basically.
What is left is high energy coke.
Unfortunately the source is a mine that doesn't wash or grade the product.
It is too stony to sell. Too unreliable. But it remains a possibility in
other circumstances.

PS I will find one of the diagrams as a reminder of the energy flow
concept.
Paul,
Thanks. I would encourage you, or perhaps a third party less invested
researcher, to produce a Sankey diagram
( https://en.wikipedia.org/wiki/Sankey_diagram ) of the Champion stove and
the entire energy system around it that you have introduced into the
Deganga area. It can be included as part of a life cycle assement. It won't
cover social impacts but it summarizes data at a glance
Crispin did this for some tested stoves. I hope he posts a link to them
again.

Paul,
It is good to see this report. You have persevered.
The charcoal was purchased back for 12 cents/kg. What happened to it next?
Was it used in the form it was produced?
I do not know about the form. Some might be briquetted. But it was sold
to restaurants and small industry for burning.
If these homes wanted to buy charcoal what would it cost?
NOT available for purchase by the households. Carbon credit agreement
requires that it be used to replace traditionally made charcoal.
Did this new supply have any change the local market price?
I do not know. I will try to have more answers in the follow-up article
about 2016 activities / expansions.
I hope that some other locations will be interested in some similar
locally-focused TLUD stove projects.
Paul
Congratulations.

Dear all,
Four co-authors have written an detailed article about a highly successful
and on-going TLUD gasifier stove project in Deganga, an area of the Ganges
Delta in India. Please read it, share it with others, and give
consideraton about how you and your projects might build upon the lessons
learned.
*Case Study of Acceptance of Champion TLUD Gasifier Stoves*
*in the Deganga Area, Ganges Delta, India*
*[Data as of early 2016; released in September 2016]*
On the Internet at: http://drtlud.com/deganga-tlud-project-2016
And attached as a .pdf file.
*Summary: *
With field data to document earlier challenges and current
success, as of early 2016 the Deganga TLUD Project in the Ganges Delta has
over 11,000 Champion micro-gasifier stoves in a small rural area. In seven
villages, between 25% and 40% of households have adopted the stove. Factors
contributing to the success include funding via carbon offsets, attaining
critical mass of households, adequate supplies of appropriate fuel, fuel
cost savings, installment payments for the BOP (Base of the Pyramid), and
stove maintenance services. Unique to this project, and very well received
by the households, is the creation of household income from the sales of
charcoal byproducts produced in the stove while cooking. Similar results
should be possible in other communities in developing societies.
*********************
Speaking personally, I have wanted this type of result for many many
years. I thank my co-authors for making it happen. Now we can look
forward to replications and variations of this study to provide the quality
of TLUD gasifier stoves wherever needed around the world.
Paul
