[Stoves] Grates and chimneys

[CHRISTA ROTH]

Xavier, I don't know of any study, but if you stick a moisture meter  
into a living tree, you will get much higher moisture contents than  
'only' 50%. and a freshly  cut tree will not lose that much moisture  
in the one day before it gets stuck into a stove. and you are right:  
it is nearly impossible to burn that type of moisture content cleanly...
do you have a moisture meter? if not, try to collect some wood and  
charcoal samples and calculate the moisture through the weight loss  
after you have dried the samples well in a kiln/oven. you will be  
surprised what you get.
regards christa
