ON your next run with just the one blower if your flare keeps blowing out ,slow the fan down to a point where your air fuel mix is correct . Nice build btw, plenty of blood sweat and tears always makes for a great build

13:20 If you blocked off some of those holes to alter the are fuel ratio, I reckon the flame would remain. I am thinking of setting the flame on the oxytorch? Firstly I dont quite know how this is supposed to work but I gather that you require a vacuum, if so, that valve in the top plate will let air in even if it keeps pressure in, it won't hold a vacuum. I may have this arse a peak but I thought I would mention it.

@@306champion G'day yeah closing some of the holes would alter the air ratio, or just turn down the blowers, the main problem I was having was the system was struggling to breathe so gas production decreased. That valve in the top plate was for when I leak tested the unit with compressed air and soapy water, I just use it for increasing vacuum in the system, cheers

Beautiful looking machine and really helpful to have such an honest narrative. There are obviously some teething problems you have identified which you will be sorting but I think you should look again at the cyclone as I’m not sure you have the design quite right. It’s not Filtering because the tube is not low enough - I realise what you said about dirty air at the bottom but that’s not how they work, and your collector does not have anything in it. The fuel feed is massive compared to the FEMA designs and the cyclone ultra small. I’ll keep watching as I know you will keep going and resolve the issues.

I have followed the process with a lot of interest and I am very eager to see how it all turns out. I am thinking that a methane digester would be a far more efficient way to produce gas. We made a very simple one when we were kids out of a 44 gallon drum with the top off, filled it with pig effluent (we had a pig farm) and a 12 gallon drum with the bottom off and a small bung on the top. Open the bung, force the 12 gallon drum into the pig shit, close the bung and by the next day the 12 gallon drum had captured a heap of methane. Basically it was a passive system with no external energy input needed to produce the gas, apart from the pig shit of course!

Might be worth ditching the gasket seal on door in favour of a channeled interference fit seems like it was close to full vacuum seal though. The trouble with rotating grate I can see is going to be a ongoing snagging issue is there a way to use a few springs to hold/suspend the grate small motor with cam and pin through to shake instead but keep the base scraper separate? Where does all the scraping go is there a box you collect all the waste that can be isolated and remove during use or is scraper just stirring the waste around the bottom continuously?

Yeah I'm changing the hatch door seal arrangement, I've just modified the grate, fewer & shorter slots. The floor scraper pushes the ash into a port at the rear and into a collection chamber, not built yet, blanked off, the agitator seems to be the weak link, will try to sort it out, before ditching, cheers.

I went back through a couple of your older build videos to get a better look at how your air intake is set up . I don't see any nozzles or a pipe that brings the air down to an area below the surface of the fuel. Are you just letting air in from the square hole in the lid? Most down draft gasifiers usually use some type of nozzles that concentrate the air near the restriction opening. This way you get one area that gets super hot instead of the whole contents of the hopper. If you don't have that super hot zone you may not be able to crack the tars which will get tar in the downstream piping and blowers. Did you end up with tar in the blowers? Now you could run charcoal instead of wood but you waste a lot of energy making the charcoal. Anyway thanks for the show. I mostly ran pellets in my gasifier and made a lot of tar till I got my reduction zone sized correctly. It would plug up on me and the more blocked it got , the lower the temperature got. I even started mixing charcoal pellets with my regular pellets and got better results but pellets are just hard to run without making tar. That's why I decided to ditch the pellets and build a custom wood processing machine that will be able to take logs and and turn them into consistent sized cubes. Hopefully I'll get it done soon if I knock out a few other little projects first. I'm looking forward to seeing what you do next. Joe

@@mazdalorean Thanks Joe, my build is a bit different from your traditional Imbert down draft, instead I've based it on the Drizzler or (Re Spanner) types where minimum fuel is feed in, always on the verge of running empty, controlled by a charcoal bed level switch, the jets aren't needed as the temperature is not suppressed by the dominating fuel load above, with the fire tube above empty the combustion will not migrate upwards through the hopper like it would in a traditional stratified setup, the rectangular hole is for fuel in feed, the 2" toe nipple on the side will be air intake when ready. Checkout the Drizzler guys in Europe, in particular Luke and Pascal. However if need be, I will run air ducts down the inside with jets above the restriction. I look forward to seeing your fuel processing machine, something I will need to look at soon

@What Happens in the Shed , yes I have seen all of there videos. I'm very impressed with their flares and their entire setup. They usually ran on pellets from what I remember. I think they ran a 4 cylinder vw engine. They also captured the waste heat from the engine coolant and stored the heat in large water tanks. I haven't seen anything new from them in quite a while. I always wondered how they got such good results from that style gasifier. Also they referred to their gasifier as "grateless " I don't ever remember seeing the bottom of their gasifier. Maybe somewhat proprietary? Thanks for the reply. Looking forward to your next episode. Joe
