[Stoves] Efficiency of clean fuel

[Peter Verhaart]

Paul,

During the (late?) eighties we at the Eindhoven Woodburning Stove Group 
measured the performance of kerosene stoves from all over Asia for the 
World Bank. We also examined some LPG stoves and the results should be 
in one or more reports submitted to the Bank.
If I remenber correctly the efficiency was quite good, similar to 
domestic gas burners many of us use in our kitchens. 70 %?

Hope this is of some use,

Peter Verhaart
