Making charcoal

I don’t know anything about your mower but getting an engine to run on charcoal is fairly easy. I made something based on Koen van Looken’s Thailand gasifier. Some school in Thailand - #21 by k_vanlooken Mine ran the first time. I couldn’t believe it. One time I tried grinding up the charcoal. Don’t do do that, it just plugged the filter. just keep it in chunks about the size of a thumb. This charcoal was made in the coffee can tlud.

my mower is a homemade pull behind i got tired of push mowing it so i took an old riding mower deck and mounted two push mower engines in the place of the belt pulleys then a hitch to pull behind the cub cadet the problem i have is one engine sips fuel the other drinks it so keeping both going and the cub cadet is a chore but it beats push mowing its a racket noise wise so i wear ear protection lol but im only mowing a drive and a small area if i can get it going on charcoal i could mow more areas to help get rid of that nasty thorn bush called multiflora rose its vicious with hook type thorns some call them saw briars

Hi Ryan , isn’t the cub cadet a ride on mower anyway ? they are here in Australia , or do you not have a deck for it , i would love to see some photo’s of it set up .
On your fire pit idea , why bother pushing soil around the fire ? once you start pushing soil into the fire it will bake it into hard lumps that will get mixed into your charcoal fuel , if your having a open burn then just lay some tin sheets on the ground and build fire on top and as they burn down to charcoal use a shovel to fill a 55 gall drum up , Trigaux has the best idea if its simple easy contained fire then just use a open drum of as large a size u can find and burn baby burn while warming and cooking and afterwards just shovel them coals into the drum too cool down .

I wear ear protection too. Makes me think you are using old flat head Briggs stuff like me. :o) Sure wish I could see your rig.

Not sure I would recommend this, but I drilled a bunch of holes in a plastic pipe and then pulled 4 socks over the holes. Like I sacrificed two pair. :crazy_face: The pipe goes through the white plastic bucket lid that you see, then a vacuum cleaner hose takes the gas to the engine. Soooo janky, but it works. I’m laughing. You can too.
I didn’t know about Joni’s chip filled filters at the time or I would have done it that way.

I cannot do it. Sacrificing holy items just doesn’t sound right.

I started out with a sock filter on my generator. Now I am using swimming pool filters they work very well and are washable. The sock filter for me would plug up after about 4 hrs of running. I can run it on the pool filters for a couple days without washing, but I tend to wash it once a day . Keep in mind this is on woodgas that has already been through a hay filter and a set of cooling rails. this is just a final filter to take out the little bit of soot that makes it there. Still I think as long as the gas was not hot they would work on a char gasifier quite well.

What does your pool filter look like, Jacob?

Is it one of those mesh screen filters or the foam filters?

This is a picture of the five I have connected together for the generator. they are made out of this very fine mesh with some foam in them as well.

Thanks, Jacob.
I will test with sawdust like Joni, see how this works.
I have half a barrel with leca balls, and it seems clean quite well, and easy to wash out.

if you saved those disposable mask that everyone handed out you could make a bucket filter lol
but a shop vac filter or diesel truck air filter would work
im useing a tractor oil bath filter but i cant get my onan to run right on gas i think maybe the carb is flat wore out i dunno its been a fickle thing im hesitant to try and fool with running on charcoal with it running poor on gas

Might be some serious tinkering involved to get the governor working with a homemade carb. But I was able to make a simple butterfly mixture control if that’s all you need. If the existing carb has a bunch of old varnish in it, I ran a slug of e85 thru my 7hp briggs to clean it out. It had the filler neck ripped out of the tank when I first got it. So I silver soldered it back on. Didn’t run good at all. I think it might fave sat for 20 years or more. Then I put about a pint of e85 in and ran it with enough choke so it was blowing a little liquid fuel out of the exhaust. Then I turned it off and let it sit for about a week. Smoked a little at first but then ran perfect.

I got a generator that would not run at all on gasoline but fired right up and ran good on woodgas - (chargas).

Don,
I have found that my lawn mower and Corolla both run better on charcoal than they do on gasoline.

Trial number 6048. Maybe this time charcoal will be engine grade. How long should the barrel be roaring?

Ha. She is on her Way.

The flames you see in the pipe are from the woodgas. Flames in the hole under are not that big.

Ha! I thought a J tube was a good idea. NOT. KISS.

Ha. And I think there will be a meld down
