[Stoves] Other pellet stove fuels

[Peter Verhaart]

Dear Crispin,
I think the air factor for liquid fuels might be lower than for solid 
fuels, because of easier dosage and better mixing.
Stoichiometrically C16H34 needs 16 O2 for the C and 34 O (=17 O2) for 
the hydrogen, makes 33 O2.
One kmol equals 12*16 (for the C) and 34*1 (for the H) makes 226 kg.
Density around 800 kg/m3 eg 1kmol more or less equals 282.5 litres.
Hoping this helps.

Cheers,

Peter Verhaart
