Introduction / first gasifier build

Hello

My name is Anti. Like many I’ve been lurking and reading in the background for years.

I first stumbled on to gasifier technology by the way of Ben Peterson some 20 years ago, I found the subject fascinating, bought his books and some of the items he sold but that was about it.

A few years back I bought the DOW plans and started thinking about it again and now I’ve decided to build a charcoal gasifier kinda sorta like Matt Ryders.

I used a 75 litre drum cut the top of installed a nozzle 1/2” ss pipe , water injection around the nozzle , a grate 8” below that and an outlet under it , a filter using an ammo can , a blower with a flare tube , got a generator of the neighbour ( which might or might not have problems in hindsight I wish I would have bought a known running generator) , made some charcoal in 50 gallon drum tipped at 45’ (that seemed to work ok) , sized the charcoal ( maybe a bit big about 1”-1/4”) and lit her up.

The results…..well not the best but not bad for the first try. The first thing that happened was I had motor problems ( got those sorted) then I think the blower was too strong and I was over drawing the system. The barrel where the air jet was turned red hot at one point and gas outlet temp got up to 200’C. I did get a flare to light fairly fast that was quite nice but the aluminum flare tube promptly melted :worried:, I also got the generator to actually run on its own power a few times but at one point I fed way too much water injection and was unable to dry it out and that was the end of day 1.

At this point I’m not looking for trouble shooting advice as I can see a lot of things I need to “remedy” but I just merely want to introduce myself and share my project.

I do have some videos but I’m not sure how to share them?

I do have some questions for someone eventually

That’s it for now.

Thanks Anti

Welcome Anti. I know you are not looking for advice but I’ll give you some anyway. Cut your char size in half and you will be a happy camper.

Nice looking build Anti. Totally agree with Don M. My charcoal fuel is sized between a quarter and three eights of an inch. A little bigger would probably be OK but I can’t speak from experience. I would ease into the water injection. You can tell quite a bit by the color in your flare. The hydrogen in the water will cause the flame to start looking whiter or clearer as you get closer to optimum water feed.

Welcome here Anti.
We do love pictures and videos here and to show videos you need another platform, Youtube for instance, to upload your videos under your account there and then post the link here in a post.
Preferrably on its own row without space or other text before and after on the same row to get its own clickable preview pic. Works otherwise as well but just the link as text then.
Good luck :blush:
