Green wood burns just great! My neighbor and I have now finished over many years the last of 300 Red Pines between our properties. We cut throw on burn pile and poof. Once you get a good bed of coals, the rounds 12-18" burn down to nothing by the next day.
Just went to buy a used horizontal bandsaw. Fellow showed me his indoor gasifier system in a large barn. Walked into the room, looked at it, smelled it and told him he just needs to dry his firewood now. Black creosote stains running out of the loading door. Firebox full of black charcoal. Heard the old normal, Nope this furnace needs wet wood. I didn’t bother.
Yeah, if he was saying it needs wet wood then he's not running it right...but just FYI, if it was a downdraft gasifier they do tend to have a lot of black goo in the upper firebox...however, if everything is working right, the lower chamber and heat exchanger tubes will be nothing but white dust. Seems weird but that's the way it works. But if he thinks it needs wet wood, I'd bet the whole thing is full of goo.
Thanks for the education. You are right, I looked it up. They recommend 20-30%. All I know is whenever I see liquid creosote stains I get worried. He was burning 8”x8” splits of red and white oak. 24 to 30” long. Probably cut within a year. I would imagine he’s a little higher than 30%. It sure did look like a nice system. Wouldn’t mind having one of those. https://greenftechn.com/downloads/WoodGunManual.pdf
I’d love to know how the people who think they need green or wet wood to burn properly keep it wet in the firebox. Any residual moisture in mine tends to evaporate out pretty quickly in the 1000 degree firebox.
