Fatboy Gasifier - Open source project 

wrong title, leads one to believe he is making gas, and he's not. Only a biochar factory here.

This is not a gasifier, this is a rocket heater, it's not even a rocket mass heater. You could do so much more with this. This is a disappointing outside space heater that is more efficient than an open pit and little more. If that's what you want that's great, well done, but you could do SO MUCH MORE with this. A few tweets and you would be able to produce woodgas which you can store and use, you cab direct the flu under your floor for mass heating and energy capture, you could add a cyclone filter and separate the tar from your char (which btw is great for wood treatment, creating old style open fire torches, and you can make pitch with it too) if you are careful and introduce a two chamber fuel system you can reburn excess charcoal in the outside chamber and pyrolise new fuel in the centre chamber. If you use pine in the pyrolysis process, if your design is not a bad one you can actually harvest pure pine oil which is a beautiful wood stain and an anti septic, if you direct the flume under your floor you cut your heating bills and waste far less energy, if insulate the fire box and your flume (since you are not worried about creosote which is going to be burned in your gasifier or filleted via the tar trap or cyclonic filter) you will even extend that use of excess energy. You can wrap your metal pipes around the flume and heat your water partially for free, coupled with a passive solar heater (made from scrap for nearly nothing) you can get warm water for free and hot with more wood being burned, but still for free. You can even use the exhaust to pull a natural vacuum through which you can at least partially compress your own wood gas for storage. I'm not trying to shit on you here but you've put so much work into that for little reward, you can make it so that much more for you. It seems sad that it isn't. Ps you don't need to put nuts or even newspaper or dry kindling in to get it started if you got done food waste that's not safe for your creatures you can ferment really strong alcohol (not safe to drink) but ideal for starting fires at ultra high temperatures, which frees your paper waste for composting or a wormery. You're obviously at least moderately resourceful and this is a wasteful use of your matter comrade. It's not a criticism, it's a if you do this, you get more back awareness thing. On an unrelated note... You might also consider a modification to your septic tank where you add a three stage system the primary holds solids and only briefly liquids, you basically put a wormery in this, they love the waste and the paper they can mulch and they produce a very fine liquid fertiliser which is particularly potent when mixed with excess nitrogen in the remaining urea. Great for tomatoes. The last chamber is just for spill over.

.Edit: I did indeed find the finished model after digging more on the site, didn't realize you were going to produce them. Great job they look excellent. WOW nothing like the prototype... the beauty of manufactured equipment.

I concur, your only making bio-char, which your turning into enriched soil, good for growing potatoes. But, no energy being used or stored from the gasses you produced, kind of a wasted effort and of the material, but, clean burning incinerator.

thank you so much, your gasifier design is an "eye opener" for me. what an efficient way to make biochar. i planned to make one, :-)

you should be getting double use of this by capturing the gas in a water bubbler tank which you can use to power a generator or heat the homes etc etc

thats not a gasifyer it's a biochar. maker

Good work, Baz.

Very impressive

Nice build, the indicator pin is unique! What does the clay add to the biochar?

So, I have something built for making bio-char, but I call mine a retort kiln. I use the char-wood in my Big Green Egg. My plans are to build a true gasifier to run a gas powered electric generator, I plan to use the char-wood in it as to reduce ash & moisture.

Not sure what are you making / doing ?

And where did the gas go? :DDDDDDDDDDDDDD

It is, in fact, a gasifier. The syngas does not have to be captured and used elsewhere to qualify as a gasifier. Here it is being directly combusted. The specific process happening to the fuel in that unit is called gasification... He is using a gasifier to make biochar.

To be fair, the process is gasification, but this isn't a gasifier for combustion engines, or the such,

How are we supposed to see what's going one with the camera so damn close

Sweet as Baz. Are these hard to build for a person who cannot weld? What do think it would cost to build and then maintain please mate? Rob Bob posted a link with the YT vid. He likes what you do a lot. Cheers mate David

Nice!

what is the true purpose of this gasifier, i see no way are you capturing any of the gasses i do like the loading design of it but i just am not sure whats the point of this design? is it to heat a house, garage or something? or just for composting? im pretty lost someone help me see what im missing because my current gasifier i built is used to run my truck and other carbureted vehicles but i can't see how you do that with this design?

It appears that hot ash and other particulates could be escaping from your stack. Fire hazard ?

Pistachio shells in paper towel tubes = rocket fuel too!

What gassifier? I saw none produced.

I'm wondering why some people have he's Tesla face ?

When you said dog bones, I thought they were bones from dog skeletons.

omg your roasting marshmellows on your dogs funeral pyre?

What's with demonic design?

2:04 *FINALLY* what to do with those human remains that have been laying around for so long!

Nice reactor

I have now modified the condenser increasing it's diameter to 205mm, dropped the flue down over the condenser to reduce tertiary air side wind issues and added a flue door for light up. My next planned changes will be focused on moving or tipping the top of the unit to allow for easy access for filling.

What one have to do when there is no pig farm nearby..

where is the gas?

Where's the gas? Totally misleading. I guess it's good info, but not for me. Thanks!

thanks a lot men, that was a very nice demo

I tried doing the dog's bones as you said but they're getting wise to me down at the kennel and limiting my adoptions to 1 dog per month now. Where did you get such a good supply of dog's bones in this vid??????

Woodchipper with bones... hmmmmm!!!! You'll have a good following here from a certain sector of society.

How is this a Gasifier??

OK, another idea that was raped from my brain, but since you on it, I suggest leaving the bottom open, about inch and a half grid at the bottom and a weight on the top, as the wood burn it should break off and fall through the grill into the water. I call this dragon poo, to charofied cherry wood, after the burn, use the remaining ash and water to make lye, stack the wood from smallest to largest, before burning.

9:51 lol.. i thought it was 18°F 😂 ❄

Can human and animal poop be used in a set up like this?

So where the gas go

its just a chimney

Tony Stark?!? >D

should be titled "BIOCHAR generator"

WHATS THE PURPOSE OF THIS VIDEO

Arrrrrm

Biochar reactor not gasifier

So... it's a damn burn barrel that serves no other purpose? Why would you bother?

I suppose its a gasifier in the sense that woodgas is created and burned off as a secondary burn, resulting a clean burn. But other than an expensive and time consuming way to create rich compost, the unit serves no other purpose. Shocking in the current line of DIY gasification projects really, the gas is wasted, the heat is wasted, not to mention all of the other byproducts which this unit simply burn's away and is thrown out as heat at the top of the flue. If you have to make expensive compost at least utilize the other products along the way instead of venting them into the atmosphere.

All that kangaroo meat I guess

It's a real energy waster. Don't you need hot water?

"beef bones "" aka you killed your dogs and 9 people thumbed you burn them

What's the point...wasted energy.....

You look like Tony Stark ...after a year in Russia :) sorry bro. it's joke. I like this movie

Ammm, Ammmm!

thats no gasifier

This system does not produce gas, and bio char should not have a through air supply to produce Inefficiently.....peace

umm, umm

HEY FRIEND, just go buy a bag of fertilizer, it's cheaper and you would not have wasted the fuel you burned or created the pollution of burning it. WHAT WAS YOUR OBJECTIVE ???? I about came unglued when you dumped that already processed chicken poo into the water, and the already processed clay powder and macadamia nuts in the fire??? THE ONLY BENEFIT I SAW WAS YOU ROASTED A MARSHMELLOW.

What a waste of all that wood / bio gas. You are not heating anything with the energy?? You are not creating electricity or running an engine?? Just letting it all burn up

Not a gasifier = hint .. make gas !!!! this a charcoal for garden ... ugh... no thumbs.. wasted my time
