[Stoves] Fuel Testing

[Tom Miles]

Kanchan Rai used to have all of the basic combustion formulas for wood
stoves interactively programmed (in java) on his website at the Research
Development and Consultantcy (RDC) Unit, Kathmandu University, Nepal.
http://www.ku.edu.np/ Unfortunately he has gone to do graduate work in
Scandanavia, I think, and his website is shut down. Maybe someone who knows
him can get him to turn it back on. His stove development work was quite
interesting. It was reported in Boiling Point Issue 51 (January 2006): High
altitude smokeless metal stove research and development Kanchan Rai, A.
Zahnd and J.K. Cannel http://www.practicalaction.org/?id=boiling_point

I'm sure that others on the list have spreadsheets that they might be
willing to share. We can put those on the stoves site at
www.bioenergylists.org

Subject: [Stoves] Fuel Testing

Dear Stovers,

I'm about to present my 'introduction' formula (in Excel) for the fuels
program.  Only thing left is running a few examples of different fuels
through the program. 

Also; There is a part I would like to add but do not know how and would like
some help. I have the calculations for carbon densities. I think I would
like to subtract from that the carbon needed to remove the water from the
fuel. 

My questions are: If you use dry wood to boil a pot of water and determine
the energy produced. Then take the same type of wood and soak into it, say,
100 mls water and repeat the test is some of the energy in the wood reduced
because of the water or, because the wood will dry during the fire and the
carbon later used, it doesn't make a difference?  If some of the energy
(carbon) in the fuel is needed to first remove the water (cooled to make
steam) is there an estimate of the amount of carbon 'wasted' to remove a
gram of water? Am I thinking about this in the right way?

Thanks

Frank
