Wow, thanks for all the great info guys!!! It will take me a day or two to go through it all. Not because I’m slow but because there’s so much to see
David, thanks for bringing me back to the Simple Fire. I had seen that first video of Gary in front of the wood pile and didn’t realize so much development had continued with the design. I’m working through that long thread first to get educated.
Don, that is a great, compact build! It’s cool to be able to talk to you about it. Do you still use popcorn as the filter? What is your reactor tank made from and how many gallons does it hold? How long a run could you get from it if you were mowing your lawn (while upgrading your 60" mower to wood gas)?
Hi Carl, thanks for confirming the approximate 3 gallon equivalent to a quart of gasoline. Water sounds nifty but that would definitely be a future upgrade. When you say I’d end up with half the charcoal in the tank at the end, why is that? I’ve seen these units run on youtube but I haven’t seen them shut down or run out of gas before so I’m probably missing some obvious operational things…
As I learn more about this system (Simple Fire) I realize that the fan is to draw all the air out of the system. So I see that refilling would undo that. But if the engine is off and you dump more charcoal in, I’m assuming you’d just run the fan for a bit (or crank the engine) until that new air is evacuated and you’re back in business. Maybe?
That Leitinger nozzle sounds perfect. Seems like you could just take a big chunk of steel roundstock, drill down the center 90% of the way, drill the air ports in from the side and pipe tap thread the one end and you have a super massive nozzle.
I produce charcoal currently in my wood stove in the house. One small batch at a time. Without trying too hard last spring I made two chicken food sacks of charcoal. I’d need to make a better grinder and sifter. That production was for biochar for the garden. But to run the tractor, I think I can make enough during a heating season.
You guys are the best!
