[Stoves] Energy in different fuels: was Re: 160 grams of charcoalboils and simmers 5 liters/CF04 Stove

[Tom Miles]

Paul,

 

I'm sure that others have a handy list. For the time being let's see if this
table comes through:

 

Energy Value of Various Fuels, from "Cooking Fuel Options Help Guide"

http://bioenergylists.org/en/UNJLCguide  

 


Energy Value of Various Fuels 


Description: 

Heating Value Fuel (MJ/kg): 


Wet Firewood (60% moisture content) 

8 


Cow Dung 

10 


Tree Residues (twigs, leaves, etc.) 

13 


Agricultural Residues (straw, cotton stalks, etc.) 

13 


Air Dried Firewood (20% moisture content) 

15 


Densified Briquettes (wheat straw, rice husks, bagasse, etc.) 

16 


Oven Dried Firewood (10% moisture content) 

20 


Peat 

21 


Charcoal 

28 


Charcoaled Briquettes 

30 


Kerosene 

44 


Biogas 

45 


Liquid Propane Gas 

46 


Note: Heating Value = Energy Value = Calorific Content 

Add;

Ethanol (LHV) 26.7 MJ/kg

Biodiesel 37.8 MJ/kg

 

On Bioenergylists.org go to "Fuels" -> "Properties"

http://bioenergylists.org/en/taxonomy/term/588 

 

I didn't see a value for "Fireballs"

 

The tabulated data is all higher heating value (HHV) or Gross Calorific
Value (GCV).

Lanny and all,

 

How do XXX grams of charcoal compare with the energy content of a 

similar weight

of alcohol, and other stove fuels, NOT counting on the energy used/wasted to

create the charcoal or alcohol, etc?  We note that there are about 15 

mJ per kg

of wood (allowing about 20% moisture).

 

Do we have a table of this somewhere?  One table I found via Google 

that refers

to vehicle fuels gives some comparisons, but not including charcoal, and the

ethanol is E85, and the units are gallons.  Not much use, but you can 

see it if

you want to at:

http://www.eere.energy.gov/afdc/progs/fuel_compare.cgi

 

But what comparative tables do we have for fuels for stoves?
