[Stoves] Request for "Efficiencies" data of stoves

[Paul S. Anderson]

Dear Sander all Stovers, especially the number crunchers!!

I have received a request for data from a Danish professor who is not  
on our Stoves listserv , so be sure that any replies include his  
address as well as the Stove listserv.

The request (below) will raise some questions.  Which efficiency (of  
combustion or of heat transfer to the pot), and what could possibly be  
"an average stove".  There is no agreement about that, and I am  
suggesting that he selects eventually 3 to 5 "average" stoves.

Also his indication of fuels is different from our normal topics.    
Biogas is the topic of other listservs, but maybe some Stover is also  
well informed about that.  And then he says "coal".   Sorry, I think  
he should be considering dry biomass such as wood (which in itself has  
many variables to be noted).

I hope that the Stovers can provide assistance to Sander.

Be sure to include him in the responses you send.

Paul
