Wood Facts A Series Wednesday

Reading about all the cold weather made me go for warm today.

Osage Orange {Maclura pomifera} is the species of wood that produces the most heat when burned, approximately 33 million BTU's per 20% air dried moisture content cord. A cord of wood is 4 foot wide x 4 foot high x 8 foot long {128 cubic foot} and has on average 80 cubic foot of burnable wood, the rest is just air space.

David, in your research about Osage Orange, did it talk about how long it will burn?  A nice dry piece of fir will put out some serious heat, but it burns up so fast it's hardly worth the effort of cutting it.  Just wonderin' 'cause a lot of people around here burn wood for heat (not that we have access to osage orange!).  Thanks again David!

Hi Mainewood,
Did not state how long it burns for, but on a chart of best firewood it takes the top place while fir ends somewhere down the bottom. Here's a link to the chart http://chimneysweeponline.com/howood.htm
Keep warm.

Interesting fact, thanks for the chart.

Ok, a lot of heat and a quick burn,
te burnable wood is 80 out of 128, do you know how much that is for pine or oak?

thanks David.

No idea Marcel. But am trying to find out, you have got me thinking on this one.
