Ever go camping and forget the firewood or run out of propane? With a small woodgas stove, you can forget the fuel and use readily available sticks to grill, smoke, boil, etc. Here’s how I built one out of some old cans, a pair of aviation snips, and a drill:
Another benefit of the woodgas stoves is the lack of smoke. No more smelling like a campfire, alerting game animals of your presence!
To keep from having to continually maintaining the fire, I have built a gravity fed system. There are a couple of things that I had to do to make the system work. First, enough wood had to be put in to last at least 6 hours before needing a refill. Second, the wood had to be placed in such a way that it would not jam in the feed tube. I ran into a bit of trouble with the feed tube sucking heat from the fire. To counteract, I made a heat reclaimer that preheats the fuel and combustion air from this waste heat to improve efficiency.
Here’s a video on the feed system and heat reclaimer:
Here’s a video on how I prepare the wood for jam-free feeding:
If you are new to this site or my youtube channel, you may not have seen some of my older information on my rocket stove heating system. It is a hydronic type of heating system, where the heat from the rocket stove heats water that is circulated through copper coils in the chimney. That water is then pumped to a heat exchanger and hot water tank for later use. Here are my older videos on the system:
Producing the heat:
Turning it into house heat:
This should get you up to speed on the basics of the system. It has come along quite a ways since these videos.
A lot has changed in my life, and as I grow older, I seem to have less time on my hands. As a result, I’ve decided to give up web design on my personal web pages and switch to the WYSIWYG simplicity of a blog. This should enable me to share more of my projects with my audience in a more timely manner than I’ve been able to lately. Thank you all for your support on my youtube channel and airgun website. I hope that you can find my experiments inspiring and useful to you.
