wonder why gum isnt on the chart ?

Because anyone who splits firewood wants to pretend that it doesn't exist. The only people who burn gum are the OWB users that don't need to split it and they don't care as much about BTU content of the wood (my criteria for what wood I burn is pretty liberal......did it used to be part of a tree?)

Oh ,ok. just cut four down out of the yard. got tired of rolling down the hill on them sticker balls. i guess ill burn them. hate to waste that wood.probably going to be about 5 cords
 
I was really surprised to see oak listed as higher BTU than hedge?? Every book or chart I have ever seen always listed hedge the highest. I know that it will burn the grates right out of my furnace and heat alot hotter/longer than any thing else I have evr burnt and I have burn't alot of oak as well as others.
 
This is why I look for eucalpytus. And why I threw my back out last year! Stuff is a heavy as concrete when green..

Eucalyptus 32.5 - 34.5 3550 - 4560 6470 - 7320
Wet weight per cord no wood heavier than that!!
 
Machinery's Handbook has good weight values for wood, I also have old Navy Engineering manuals that list weights but I've never seen the BTU Table good info TY

I'd have to question the accuracy of that also. I've burned hedge for 20 years but had a lot of Oak given to me so i burned the Oak last year and in no way did it burn as hot or as long as the same amount of hedge loaded into the stove.
 
I wish we had some of those hedge apple trees around here!

They're a hardy tree that take extreem cold and heat both. They make a good shade tree when not planted in row's. Thats a pile i'm starting now with a row in the back ground.

I didnt realize they got that big. Must dull a chain pretty quick!

I spent yesterday cutting one up and dragging it out that was close to 4' at the base. Tons of wood in that tree. The row you see is a little over a hundred years old. I'll get a pic today of un trimmed row to show the branch's that have grown straight out into the field. Between taking them and a whole tree here and there the pile's building up fast.

Where did you find the higher Btu listing. Where Oak is higher than Hedge?

I have been reading these charts for several years and haven't seen that yet.

Osage Orange (Hedge) 32.9 million Btu's per cord and the highest Btu rating for Oak Tanbark is 27.5 million Btu's per cord .

These #'s come from Sweep's Library: Firewood Comparison Charts

I found it! I believe http://firewoodresource.com/firewood-btu-ratings/ is the site you got that from.
They state Live Oak is 36.6 million Btu's per cord.
I would bet whoever listed that on there site got some numbers mixed up or didn't verify there info.
Live Oak 36.6

I question some of the info as well. First Both Lodgepole pine and douglas Fir are heavier than listed most on most charts. And strangley Doug Fir bark when its dry burns hotter than any thing I have ever encountered. It even burns hotter than any hadwood I ever saw Be danged if I know why though. Also I have an old book at home that lists Pinon pine at 41
:chainsawguy::blob2:
 
Got to remember they are talking about total heat over the entire cord. Many kinds of wood burn hotter but go so fast they score low BTU's in the long run. I have some junk wood I burn now when I want a quick fast fire that will melt the stove but is used up in an hour. Oak would burn all day at half the temp but do to the time difference scores higher BTU's
 
Yeah saw it before, not much listed from the leftist coast, guess we dont have trees here.
A few firs, pines hemlock n such. There is a ton of eucalyptus( gums) species here, the charts Ive seen list them as tops/near tops in BTU's......
I found it, here it is...

And since Kalifornia feeds the world we have avocado, almond, citrus wood (crap), pistashio, walnut groves, cherrys (real cherry trees like in my front yard), pears, apples, plums, peaches, related species, grape wood, etc etc. And they all have a livespan, and we burn all of them.

As another cali Bro, I agree we have lots o wood to burn.. Avocado sucks! low BTU , smells bad, hard to keep a clean chimney. Just junk wood, like poplar, in MHOP. The BEST wood out here is Red Gum Eucalyptus, followed by other euc sp., then probably deciduous Oak out of the mountains. I see all kind of crazy BTU #s for wood, but we can call BS on the numbers if you've been a wood burner for 20+ years!!!:chainsawguy:
