Dear Dr TLUD,

 

    An ANALYSIS PROCCES of dry wood (120°C for 10h ) is done in a BOMB REACTOR with 100gram wood and  filled with nitrogen and airthight heated to 500°C for 15 minuts .

Clooled, degassed and the remains are CARBON your 45 gram CHARCOAL .

SO you use an extned heat source stat the half of the fuel .

 

Regards

F.

 

Paul,

If you do what is called an “Ultimate Analysis” of the dry wood fuel you will get about 47% of the dry weight as elemental carbon. (ASTM method E777-17). The carbon is physically in the form of cellulose, hemicellulose and lignin. When you heat the wood in pyrolysis or gasification you will get about half of the carbon in the form of charcoal. The rest converts to CO, CO2, or other gases.  

 

Tom
