[Stoves] Other pellet stove fuels

[Crispin Pemberton-Pigott]

Dear Dr Tom

"The A/F ratio for wood is about 1.5.  For starch and carbohydrates it is 
probably more, and an oxygen (lambda) sensor on the exhaust might give a 
good monitoring of the flame needs. "

I wondered if that was for combustion or gas production or both....

Can I calculate the air required for any fuel using the chemical formula
alone?

For example what would it be for paraffin if it averages C16H34?

Or diesel at C19H40?

Thanks
Crispin
