    Default old pine

    I have as much old dead pine as I want, but will it burn good? Most of this is red or jack pine that had a disease about 10-15 years ago. Some of is has been down on the ground for years but was cut up and stacked last spring to clean up the property. How well will this burn in an evaporator?

    Sorry this may be the wrong place for this. Can a moderator please move this to the room talking about fire wood.

    Thanks,

    Taken care of Rob... and to answer your question, I wouldn't bother with it if it's old and decaying. I haven't used it in my rig but based on the fire pit it has always been far more work to keep punky logs burning than it's worth and often requiring perfectly good wood to do it.

    We used pine last year. it burns great however you won't get the BTU of a hardwood from pine. This year we have mostly hardwood that is split wrist sized. I do have some pine that i will mix in. I like pine for getting the fire going and hardwoods for long hot fires. With the pine we had to fire about twice as much as when we used hardwood. Here is a list of the BTU output of wood. Should help you. If it's cut already then burn it.

    Pine burns very well, if there is little or no bark as long as it is not punky. The bark on most evergreens has evolved to protect the tree in a forest fire. It has it's own retardant. If split well, this does not hamper it but do not leave whole unsplit pieces with good bark still on it. This should not really be an issue for 15 yr old wood.
    I once put 1 pc of unsplit fairly fresh cut hemlock with a huge number of limb stubs, maybe 6-7" diameter in the evaporator just to get rid of it. That piece was still there an hour later, and after re fueling around it every 7 minutes. Never again, it messed up my boil rate for over an hour. That was before I had any blower for combustion. I don't know if that might help.
    Dave Klish, I recently bought a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
    Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
    Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
    After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.

    Thanks guys. Some of it i am sure is punky. I wonder if a blower on it will help out the punky wood though. If i decide to use it i plan to move some of it this weekend and cover it until it is needed in the spring. It should dry out nice by then. I would think even dry punky wood would burn then. Am i wrong?

    I have had a hard time gettin pine that was punky to dry. And when it gets dry not much heat. If it is not punky it is worth using.

    Will a larger piece of pine generate the kind of BTUs that a wrist-sized piece of hardwood puts out?

    I picked up a batch of seasoned quarter-round pine that is so knotty I can hardly get my maul through it. I'm at the point where a lot of the pieces may just have to go into the evaporator as is. I have enough other wood split small that I could just work one big piece in once in a while.

    Do you think the big pieces kill the boil?

    Am I the one thats confused or you BTU guys? Seriously here is my thoughts and deal with the BTU debate. BTU's for wood are based on a cord of wood correct? Now we all can agree that a cord of hardwood burns longer than a cord of pine right? So with that said you get more BTU's out of a cord of hardwood than a cord of pine. Any one disagree? But guess what I could really truly give a rats behind how many BTU's I get out of my sugar wood cause my only concern is how darn hot the wood burns to get those pans ripping. I am willing to bet that if you were able to measure the temp of a good dry piece of pine and a good dry piece of hardwood you will find that the pine burns alot hotter just for not as long. Personally I would rather be shoving wood nonstop so I can get to bed sooner than be throwing in wood less often and be up longer. Done it both ways and I will pick up a piece of pine before I reach for a hardwood in my evaporator.
