Woodgasifier/Generator, Completing the Filter at Long Last

[@senorjp21]

Terrific craftsmanship

[@whathappensintheshed]

Thanks mate

[@thierrymarti5895]

Finally another Woodgasifier video! I love your work!

[@whathappensintheshed]

Thanks mate, much appreciated

Splendid progress, my fellow woodgas addict :) . Seeing all the metalwork that you are doing, it occurs to me that a CNC plasma cutter would be a wonderful asset. One of these days, I am totally gonna build one of those. Keep up the woodwork, oops, I mean good work :) .

[@whathappensintheshed]

Mate, I so much need a plasma cutter, been watching some CNC kit builds, yep that'll do it. I'll start with a plasma cutter first, I have a space problem in my shed, I need to finish the gasser and get it out, only then can I contemplate what to fill that floor space with, cheers

[@CNCmachiningisfun]

@@whathappensintheshed Yup, it looks like we are in the same boat. Looking for space, and an affordable way to fill it with a CNC plasma cutting solution. Dunno whether to build or buy, as it all comes down to cost VS performance, I reckon.

Makes me want to go with in my garage, what an inspiration you are 😁

[@whathappensintheshed]

Thankyou very much, that has been my aim, to share what I'm doing with others, thanks for the feedback, cheers

Good job. I admire your attempts and problem solving. You keep moving forward. Unfortunately, I stopped trying - lack of funds. You can't imagine how many common points our projects have. I would like to support you with some comments; 1. Use wood pellets instead of wood chips. You will eliminate many mechanical problems resulting from the use of wood chips. After achieving stable operation of the pellet generator, you can return to wood chips and optimize the generator's operation in this respect. 2. Consider the thermal insulation of the generator heart. This is crucial. I recommend using vermiculite or a similar board (resistant to temperatures of at least 1,100 degrees Celsius) that will be in direct contact with the fire. This direct contact eliminates the problems of steel at high temperatures. Unfortunately, this requires design changes. Ceramic fiber insulation can also be used (minor design changes). 3. I admire your ability to join metals, but it is equally important to control and monitor process parameters. Without process control automation (at least PLC with sensors), success may be incomplete.

@@dariuszkubicki9219 thanks for the feedback, much appreciated, we're in the subtropics here where heating is not a big thing, so wood pellets are not available, only for smoking meat etc. I have gone over to a more chunky fuel that has helped, once I get this running properly I'll start insulating it and being with automation and so on. Main thing is I'm having fun, cheers

[@whathappensintheshed]

@@dariuszkubicki9219 I'm sorry to hear that you had to stop your project, fingers crossed you'll be able to start it again soon, cheers

Really appreciate your work. Wood gas creates a couple acids which eat the pyrolysis cores at the bottom neck. Do you think it would be a good idea to go through the expense of getting the core ceremic coated like is done with high-end automotive heads & pistons? Thanks again.

[@whathappensintheshed]

@@denverbevins4052 Thanks mate much appreciated, I have seen guys playing around with ceramic chokes, but for the time being I'm stuck with mild steel, once I've got a proper working unit I probably will explore using other materials, thanks for the feedback, cheers

[@fraid5508]

What kind of fuel do you intent to use? Charcoal or dry wood?

[@TheNicestAssholeYouWillNvrMeet]

Probably a combination of both.

[@whathappensintheshed]

Hi, exclusively dry wood, only times on charcoal is after a major service or teardown, every startup is on charcoal from previous run, once up to temp. feeding of wood fuel begins, cheers

[@TheTwistedOutdoors]

Are you gonna have plans and parts list?

[@whathappensintheshed]

@@TheTwistedOutdoors Short answer, no. The first reactor I had fully detailed drawings and bill of materials, but I very quickly strayed away from the design and started doing things on the fly, I'll do up sketches on CAD and then go from there, cheers

[@kastlunger]

how are you filtering the gas? We have 4 huge wood gasifiers. Running since 12 years. The biggest is making about 200kW The biggest problem in our systems is the lifetime of the filters.

[@whathappensintheshed]

@@kastlunger The filtering is done by the straw and foam filters, the last two test runs it produced virtually no tar so I'm hoping the filter will cope, 200kW now that is huge, do you produce electricity, or is it for biochar? Cheers

Thank you and thank you and thank you!

No worries, thanks for the feedback, cheers
