Dear AD, Priya, and all at ARTI,
Good that this topic has come up again. And thanks to Alex for posing
a good list of questions for updating all of us.
But I went to the Stoves website and could not find a good description
of what the process is. The is one piece
http://www.goodnewsindia.com/Pages/content/discovery/karve.html
that has 2002 and 2004 dates on it, and it shows one picture of the
kiln of that time, with 7 barrels in it. But from when I visited
ARTI in Phaltan (about 2006) there was a mobile unit that was taken to
the fields. I do not see any write-up. Is there some broken link
that someone can resend? Or whatever the Karve's can provide.
I am requesting some background info upon which the responses to
Alex's questions can be referenced.
Thanks.
Paul

Quoting Alex English <[email protected]>:
Dear A.D. Karve,
You have now been at this for a decade or so. I, predictably, am
just curious to know more details.
Perhaps it would be useful information for others too.
Concerning your TLUD style kilns, can you share with us ;
1. how many of these kilns are active,
2. how much total charcoal all the kilns produce per year or season,
3. what percentage of ARTI charcoal briquettes are made with
charcoal from these kilns,
4. how long it takes to earn back the purchase price of the kiln,
5. how long the kilns last.
6. are the number of these kilns in use still growing.
7. is there a subsidy for any part of this energy production-stove chain.
8. has the kiln been adopted beyond your region.
9. what is the bulk density of the charred cane trash as transported
before being briquetted.
10. average distance it travels from field to market.
11. Are any wheels involved in the cane fields, either moving the
kiln to the trash or the trash to the kiln.
12. Are there any concerns about the loss of nutrients from these fields.
Warm regards
Alex English

Dear Stovers,
we are currently using 200 litre steel barrels for charring sugarcane
leaves into charcoal. Our kilns work on the TLUD principle. Since
sugarcane leaves are light in weight and difficult to transport, we
send our kilns to the farm where they are harvesting sugarcane,
convert the dry leaves into charcoal and bring the charcoal back to
our briquetting facility. The gaseous part of the leaves is burned and
exhausted. Being an ambient operation, we cannot harvest or use the
energy generated by burning the gaseous fraction of the biomass. But
since sugarcane leaves are in any case burned in the field itself,
nobody mourns for the loss of energy.
Yours
A.D.Karve
