- Wood gasifier doing a test run on shelled corn explodes shortly after using the shaker grate. I think oxygen rushed in through the open top too quickly to be burned, mixed with the gas in the barrel, and exploded.

The main trajectory was at you because Karma hates stupidity.
2:55; You're welcome
You’re a good person
I don't know if you had a char - bed set up in your reduction zone. Corn is a poor fuel choice. It is difficult to maintain a 20 % or less moisture content of your fuel. Corn is loaded with starches, you add heat and it breakes down into simple sugars, Under extream heat and when you did the shaker you had the hopper lid open an unlimited supply of oxygin to the fuel mix, you got your gasifier to backfire the moment you used the shaker, In gasifier operations this is called a puff back. Your puff back was more violent of a reaction because of the sugar in your fuel, Also it's a good idea to make sure your fuel size is correct and proportionally larger then the holes in your grates and it's actually ash when it passes through. Down draft gasifiers are designed to run on wood or wood products. The sugars produced by your fuel choice will continue to be problematic.

What if he used dried hemp stalks?
Did you use popcorn?
That's exactly what happened...hahaha
My first thought where's the butter
Hi Bob
I'd say 99% the air came form the door.
Shaking the grate just brought some hot ambers as an ignition source.
If it was too much air going through the bed it'd have started burning.
You might try using fiberglass rope as a gasket.
The corn popped in your hopper, lol. Cool man, glad yer ok.
the oxygen inter from the rod hole when u shak it and cause that explosion
Was you surprised not to see pop corn when you opened the door? lol
I didn't get a good look at the door, but no matter what if you have to ever open the top during operation then that weak ash door is a safety hazard. I think you may be right for the reason why the door seal failed, but the fact is that door seal can fail when the top is opened, shaking the grate or not if just out of freak accidents, if the bottom gets too much air at the same time it has highly flammable fuel available it will burst that weak door seam. I think it would be good to make a better door seam that can handle the pressure if/when that happens while the top is opened during operation. Mechanically the door must be stronger and mechanically sealed not just sealant.
who could have ever guessed dried corn kernels would pop. you might have something there.
popcorn
been there done that, with a 60kw output gasifying boiler ... sure changed my hairdo for a month, glad i had safety glasses.
The definition of an explosion is "a violent and destructive shattering or blowing apart of something, as is caused by a bomb."
I didn't see that 😂😂😂
Nope. Explosion is an fast gas spreading in limited space container. It can blow apart the container or blow a hole in it
Was the definition of an explosion to an ant
Hmmm, that must have been caused by "Pop Corn".
This kind of thing is normal, and is often called a "sneeze".
You will eventually get used to it :) .
Well, I think that it wasn't just from the corn, currently working on better sealing of the ash door. Don't want to worry about this all the time. Thanks for the comment!
tonto bob
Explosions are fairly normal in gasifiers, so it is something we have all become accustomed to.
On my first gasser, it used to explode so violently that it would send burning material up to a height of 60 feet.
At night, this was always an amazing spectacle :) .
That happened to me today, blew my semi-permanently sealed ash door 25 yards down my driveway, and bent the hell out of the barrel lid, sounded like 5 shotguns going off at once. It happened when I finally burned through the corn brick in my reduction zone thus allowing a large amount of air immediately able to rush into the barrel. Not going to use a barrel anymore, going to put the reactor core in a less voluminous container, like a 30 gal propane tank, so my "pops" aren't so violent due to less gas volume and better metal weld-ability for sealing purposes.
+tonto bob
Yup, I hear ya bro.
The barrel is ok, but that huge volume does scare me a bit.
Propane tanks, or even air compressor cylinders, are surely a safer bet.
Your thinking is pretty solid, so you are taking the right steps and learning the right lessons.
Keep up the good work.
Trying my best, steps backward will hopefully turn forward by the end of this.
I think you came out quite well on this. Do be careful. Best of luck on your next try. Good to see some one willing to test and try ideas. You learn so much from experiences. Glad you made the video of it and sure does make it easy to better consider the causes and avoid them. Might check air getting in around the shaker shaft. You might even close up the unit as best you can and blow air into it and see where there is any smoke or air coming out. Best of Luck on your next test.
The machine farted!!!!!!
Exactly
I heard another guy say that if you move to much air with the fan at start up it will do that. Maybe cut the draw down a little.
When you added the corn it was too much and it smothers itself only temporarily then it ignites in an explosion. I have a corn burning furnace and I've done this by hand feeding corn in trying to build a larger fire quickly in witch case I did.
What ever you bolted your door on with could not take the extra high temperature of the corn, and the expansion of the bolts causes them to fail, I know this because I've had bolts shoot at me like bullets
technically speaking aside....that was a robot fart.
I use corn to make mash.
tracksmoken trapper how to make corn mash and a still ??
How ? What is the best way, ingredients, time, taste, (lead free solder) shape, what's the Thumper for, little things like that ?? Thanks for any and all information about this subject !! I don't think that people can get arrested for sharing information, they certainly should not be, it's a violation of the Country's Constitution and the Bill Of Rights to suppress knowledge !! Free Speech and so on.
Well that’s what you get when you run your engine on popcorns
the air is coming thru the top . the vacum fan or engine should be off when lid is open maybe
Some explosion 😏 that was backfire 👏🏾👏🏾👌🏾
true
Where is the pressure relief valve?
You opened the relief valve!!!
Holy shit, man! You’re dangerous!
Haha you call that an explosion?
It was more of a burp, wish I got the next explosion on video. Sounded like a shotgun and blew my ash door 30 yards down the driveway. Was pretty sweet.
tonto bob did it damage the furnace
The one on video here didn't really. But if you watch my more recent vids you'll notice the main unit is no longer in a barrel, it is in a propane tank because there was another catastrophic explosion that DESTROYED my barrel.
tonto bob I have plans to build a gassifier one day and I have an old 60 gallon air compressor tank I'm gonna use for the furnace
david jenifersonn
It's called click bate. It worked we are all here😜
Keep up the videos bob
yeah dude, each kernal of corn has water in it, and exploded at about the same time, this means your heat is even, and hot, since you had multiple kernals explode within several hundreds of a second with each other. Like a bunch of firecrackers going off at once, from the water pressure.
EXPLOSIONS ARE EXCITING.
Too much popcorn. When you shook the corn hit the hot grid... too much at once, the corn pops!!
corn is an odd one, but thanks for showing what others may be hiding, afterall, who wants to show hiccups in there creations.
Hi tonto bob,
It seems that you need a door mating ring that is welded to the drum. This will stiffen the drum and prevent warping..
So dangerous, be careful. Any smug as well? Did it suck the air out of you?
Some of the videos I've been watching said that if you allow your fuel to get to low you will get a cycling of fresh air and then not enough air causing small explosions where it is burning. I am definitely no expert on this subject I have never made one or even seen one operate other than on video but that would be my guess.
corn explodes with temperature like popcorn ... Tontin
Not the first on TH-cam. I think I beat you to that! But what generally causes that type of FHOOP is too much air. Mine exploded due to the blower pulling air in too quickly.
Was it popcorn? I can't be the first person to suggest that as a smart ass.
Your rattler-spindle looks like a loose fit in the hole. That will admit air enough for what appears to be a rapid 'progressive burn', rather than an explosion.
do you think a Gasifier would make enough heat to produce steam when burning wood?
the core gets to 2000 Fahrenheit, and the outside of the hopper, main unit, and first cyclone get to well over 600 Fahrenheit as well. This is wasted heat if not insulated properly, and it could be used for many things. So yes.
neat.
RTV will only withstand 600 degrees F. Your door gasket looks deteriorated and O2 will suck in there and boom.
I rebuilt the main unit, and redesigned the ash clean out, pretty sure the ash clean out is perfectly sealed now. I have the new unit in newer vids
what happened was backdraft close the top also
its called built up pressure/ popcorn...
It looks like you caused air to go down to the bottom and mixing with the fuel you dumped in. Lucky the gasket failed and you didnt go up like the sultana lol
Soft as beans bro!
To heck with Mr. Fusion - this is cooler
Popcorn?🤷♂️ dont burn corn ... 😂
You need to crush the corn bud..
Lets just say that Corn has explosive features..
(Pop corn is a sign)..
That is why I believe that raw corn gives off a bit of ethanol in very low forms.
Even without formatting it because it did a similar thing to me...
That was because the expansion of the corns.
Corn kernels have moisture in them, they will explode with steam pressure generated in side each kernel !!!!!!
is that the same as a backdraft?
Your suppose to burn corn cob ground up, not corn. You are suppose to use high temp red rtv.
corn is not too good for this purpose. it contains lots of water that turn into steam in the shell and eventually explodes into popcorn....
Looks like air or moisture got trapped and door was used as a safty vlave
It look to me like you got a air leak under you hearth that ignited the gas
try dried corn cobs w/o the corn. they burn well
You know they make ethanal out of corn that goes into our gasoline
dito backfire, over pressure the ash pot, too much fuel in ash with air. Incomplete combustion before dumping into ash pan.
Surely you could a gasifier put together better than what you have now. I thought your suppose to use wood chips, pellets or very small cut wood chips?
Explosion?
you shook the grate, this made a small dust cloud inside your barrel, dust is explosive !!! thats what you had was a small dust explosion. be care full checkout dust explosions on coal fired ships, some have completely destroyed their ships !!
more of a corn fart
ESPLOSION 3:00
Hahaha... happens all the time... nothing to worry about... it is called... sneezing ... if the hatch isn’t sealed enough and tight that happens...
Thats why there is a spring on top of the generator hatch.. so the “explosions” can go somewhere without damaging the generator!
(Check the clip of my car at my channel)
You invented popcorn! Would you like to move toward feudalism or space travel?
lol, well, lets see...……….hence, that's why we call it "popcorn" ?????
That was a deflagration, not an explosion.
compleetly normal, dont wet ya pants
And ah. But ah. So ah. Uh...
U have to meet mr tesalonian between u two Lordy!
How to not make corn nuts
Corn has a lot of water in it, maybe try some other fuel.
muy buen dia le pregunto me podria dar un plano o esquema de esto. muchas gracias
Mira mi serie de videos: "Gasifier build for dummies," tiene information te quieres, Pero no en espanol. Gracias!
thank you
You gasket 100% failed... cus you got air in threw the shaker handle...
Burn the corn or distill it but not cook it for pyrolysis. Big popcorn maker is all you had there.
Hahahhahahwhhahajahahahshahahahahahahahahaaaaaa aaaahahahhhahahaha wait for it...ahahahhha
Too much air pulling through..
You call that an explosion try making a hydrogen generator and forgetting the spark arrestor
explosion? more like a fart i think
Like that didn't look staged
That was cool! Be careful! U have nice face u might want to keep it
that was hardly an explosion, you still have your hands and head. lol
2:55 its pretty disappointing
It happened because you have mega air leaking in. Your door sucks air, man, get real.
You lied…you pulled a pretty greasy move, young man…ClickbaitING people. Not cool.
well, he was getting plenty of smoke when he shut'er down. And honestly!!! The popcorn is ruined !!!!! Believe I'll just stick to the electric stove for MY poppacorn!!!!!!
I think you should not be building anything because you are a danger to yourself
Get e welder use metal plastic lol
Hey kid guess what happens when you pressurize steam it blows up guess what happens when you heat corn it produces steam 🤣🤣🤣🤣🤣🤣🤣
CLICK BAIT
That was a sneeze, not an explosion!
your shaker allowed the charcoal to particularize into the air below the reactor, and because you were burning corn (which burns very hot indeed because of the sugars) with a high volume of oxygen travel across the particularized charcoal, you generated a flash-over.
Fuel + oxygen + fire = combustion !
EXPLOSION? Says the guy who thinks getting a kiss on the cheek is 3rd base.
In your next build, you may not want the shaker directly over the cleanout.
I think you just the designed the world’’s biggest popcorn 🍿 popper!!! Congrats!!!! 👍😃
Hahaha
🤣🤣🤣
You need a top that is fixed with some heavy duty Springs so when a sneeze occurs it will lift the top up to release the pressure. Otherwise your just gonna keep blowing out at the weak point and potentially hurt yourself.
4:12 funny how the main trajectory of embers was right at me.....while i stood in front of the place with least resistance....duh yuck............ Please tell me, you've since blown your hand off or eye out.
dude....that contraption, 🙄looked like an explosion waiting to happen. glad your ok.
I applaud you were not afraid to show your hiccup in your experiment sir...
