Fuel processing is a big issue to me.
I have thought of how to “feed” my Keith gasifier, and the best plan I have come up with is to buy wood scraps from a nearby handle mill. These scraps are 100% hickory, and come in pieces measuring about 1" to 2" square, with lengths typically in the 1 foot range. I would have to make a “mini-chunker” to cut these down to about 2.5" long.
I think a guy from my area (Denny) brought some of these scraps down to Wayne a few years ago, and they worked out pretty good.
I am a little frustrated that, even though I have a sawmill and access to an unlimited supply of slabs, etc. I can’g come up with an idea to process the fuel as efficiently as I could those hickory sticks. However, I can get the sticks for very cheap, and they are uniform.
Most mills nowdays have chippers, and I would add a chipper to my mill if it made good gasifier fuel. However, I am thinking that it might be a little too fine for the Keith gasifiers ???
