I joined the site after the article about Wayne came out in Mother Earth News. Bought the book when it got published and built a Wayne Keith gasifier modified with an 8 inch fire tube with the intention of using it to power a generator. I ran a couple of test runs and just flared off the gas but never hooked it to a generator. I had no chunker of any kind and it was a lot of work furnishing fuel for it so satisfied that it would work if needed I set it aside. Then I burned down my shop and most of my fabrication tools. Being 69 at that time, retired and on the usual fixed income it was a struggle to get a new shop built and furnished with a minimum of cheap Harbor Freight tools. So it’s been quite a spell since I had the time to invest in gasification on any level. Now I’m interested in building an updraft charcoal gasifier that it would be possible for an on-line group for prepper homesteaders I’m involved with to build with basic fabrication skills.
It seems that most of the projects people were doing in this area were some years ago. I like the unit they built on Off-grid/pro but there are no recent reports from that group. I am thinking of something like the Troy Martz gasifier but again no recent reports. I’m wondering if those units somehow failed to work after further testing. I’ve tried to study what in the DOW forums but it’s information overload. I’m 73 now. Not sure I have time to read thousands of posts. I also like the Ben Peterson unit he put in his Mustang but that’s too complicated for my friends to build. So some of the questions I have are,
On the Gilmore simple fire units, how is the ash dealt with?
Why would someone use multiple nozzles if a single nozzle is sufficient to provide useable gas?
I’ve seen several videos that say a charcoal gasifier must have a full hopper before start up. Can a half full one be started?
My generators are hooked up for gas and propane. Does wood gas have to be pressurized to run it though the propane regulator or does some kind of by-past have to be created to pump it in past the regulator?
Probably stupid questions but give an old man a break.
