[Stoves] Stoves using wood and charcoal at the same time

[Crispin Pemberton-Pigott]

Dear Dr Tom

 

If you could read my letter to Dr Lloyd, can you comment on the "Stove LHV"
for charcoal?

 

Thanks

Crispin

 

>Wood can be looked at as a carbon hydrate, ie

CH1.4O0.6 = C (H2O)0.6 H.2

with increasing temperature driving off successively .1, .2, .5 of the H2O.

Cooking charcoal is made at about 450 C, driving off maybe 0.2 of the 0.6
waters.  Pyrolysis proceeds approximately

CH1.4O0.6 + heat ==> C H O0.4 + 0.2 H2O
