Re: Energy produced by 1kg of burning charcoal

From what I know, charcoal made from different types of wood produces different amount of energy. In our region, certain species of mangrove wood are best. There must be an average figure somewhere - Wikipedia reference-linkEnergy content of biofuel

Look at the sixth item in the table and do your maths from there.

Re: Energy produced by 1kg of burning charcoal

charcoal 29.0 MJ/kg
diesel 45.3 MJ/kg
(from http://hypertextbook.com/physics/mat...ergy-chemical/)
("energy density" is a good search term here)

So diesel fuel provides about 1.5 times as much energy per kg.


Also, diesel has a density of 0.85 kg/l. Combining this gives

1 kg charcoal
= 29.0 MJ
= (29/45.3) = 0.65 kg of diesel
= 0.65kg / 0.85kg/l = 0.77 liters of diesel
