Cleaned up the work area and put the tools away. The sixth work day has ended and the sun has set. The stars are begining the show their light.
I really need this day of rest, thank Yehovah. He has given it to us to always remember this day, and if you have to work on it, remember this. Yeshua, Yehovah’s Word said this “It is lawful to do good on the Sabbath”. He did not follow man made laws and regulations He would break every one of them, right in front of the ones who would say you had to follow them. I just love how He would not follow any of The man made religious ideas. Have a wonderful Sabbath everyone. I know I will.

The double flute charcoal gasifer is pretty well completed. I just need to figure out the cyclone filter and towel tube filter for it.
The outside insulation barrel still needs to be built, this will keep it to a 10 Mississippi hot to touch or longer.
I will test it out, with out the other barrel insulation. Right where it is sitting on the metal table. My last charcoal unit was a 1 Mississippi hot in places. OUCH! I checked with a heat gun tester not my fingers.
I will be using my Kirby vaccum cleaner build to get a good vaccum draw on the gasifer to kinda simulate a engine draw. It has a variable light dimmer switch on it to control the vaccum suction. From a gentle suction to sucking the guts out the gasifer suction. I will also use a long aluminium irrigation pipe for added cooling.
Just letting the hopper silicone stove rope seal set tonight for a good tight seal.
The inside ceramic wool and stainless steel shielding is complete on the inside.
Note: I am really liking the simplicity of Kristijan’s Skoka build.

Bob,
I can hardly wait for the test run. Thank you for sharing this project with us!

Pulled the hopper off it looks like I got a good seal. The stove rope is embedded down in the grove all around.
Next step mounting the cyclone filter and clean out. Getting closer to the flaring of this gasifer.
I need to go shopping to day to buy 40 lbs. of hamburger for the meatloaf we cook on Wednesday at the Light House Ministries. We will serve about 60 to 80 people for tomorrow’s dinner. In the winter months it can be more. Helping those who are in need is always a Blessing.

I have the cyclone hooked up temporary and long aluminum pipe for cooling, the Kirby vaccum will be hooked up at the end of the pipe.
But the wind started to blow and the rain is starting to drop great big ones. Yes let it rain! We can use it on our dry land and the fires that are burning.
The first flaring has been postponed because of rain.

It can rain for days, I do not care. I can wait that’s for sure.

I never liked the rain until I walked through it with you
Every thunder cloud that came was one more I might not get through
On the darkest day there’s always light and now I see it too
But I never liked the rain until I walked through it with you
I hear it falling in the night and filling up my mind
All the heaven’s rivers come to light I see it all unwind
I hear it talking through the trees and on the window pane
When I hear it I just can’t believe I never liked the rain
Thank you Clint Black for that pure country music gold

Whats you opinion of that Harbor Freight gantry Bob. Good value? I’m thinking about building one but sometimes it’s just cheaper to get something from HF.

I’ve had one for years and love it. However I had to replace one of the cable cranks with a hand crank wench. Easy fix if the other side ever fails Ill do the same. I paid $800 for mine new back in 2013 and had to get it to build the large machines were getting into at that time.

The HF Gantry Crane is great Tom. I got when they had a 25% off coupon and the name brand of the crane was not on the coupon saying it was not covered. It was around $500.00. It was no fun setting it up though. You really need four guys to help you get it upright unless you have a forklift or tractor with a bucket to help you upright it.

Yeah I was going to mention that as well. Yes you need to a crane to build your crane haha

I rig my motor lift up to about three feet off the ground on a platform then added a counter weight on the back of it. Extend the boom to the max to lift the gantry crane up right. It was a little scary when the wheels sled under and it was upright. Just two of us doing it. It was not a OSHA prove set up for sure. Lol

I put the ash into the gasifer. It was in the form of wet clay, the fire pit received a little rain. I packed into the spots where ash was going to form. Then it was time to load the charcoal into the gasifer. I first put some larger pieces in at the grate it is 10.5 inches from the nozzles, 2 inches above that is the restriction opening 7 inches by 5.5 inches. This area was filled with larger pieces also.
At the nozzles was engine grade charcoal.
I turned on the Kirby vaccum on to full throttle and tried to light it through the nozzles no go.
Turned the vaccum down to low. And I lighting it just above the nozzles. Added more moistened charcoal on top and put the cover on. The water that was in the ash dried out pretty quickly, and had a flare in no time. I had to do this quickly. I cranked the vaccum up to full throttle and it held the flare in my coffee can mixer. I started spraying water into the nozzles intake and was unable to stop it from flaring. The flame went from yellow/blue to invisible at full throttle. Bottom area of the gasifer was at 600° f and little above that was 500 to 400°F. At the top of the gasifer at the nozzles level was 370°f.
Gas coming out of the gasifer was at 390°F going into the cyclone. The paint on the cyclone started to discolore at the top.
I ran for 10 to 15 minutes two different times and at different velocities.
It works! The next run for the gasifer will be hooked up to the Dodge Dakota truck cooling rails and let the truck engine pull some charcoal gas into the engine and run.
It is running better than I was expecting. The continuous spraying of water into the intake was very impressive, lots of Hydrogen being made, The Kirby vaccum did great it was up to 220°F at it’s intake and climbing when I shut it down. I did not want to melt down the plastic intake hub on the vaccum.
Definitely will need more cooling.
The cyclone had about 100°F difference going into the cyclone and going out.

Very impressive Bob
Just don’t melt it down, can’t wait to hear your new top end speed.
Do you have a way to add water when it is in the truck?

I am still thinking how to insulated it and security strapped it down into the truck. The bottom cooling rails will be disconnected from the back posts that feed down into the condensation back tank. The rails will be hooked to the cyclone out put, this will force the gas to move up the cooling rails and then down the two other cooling rails on each side and then down into the condensation tank and then back to the hay filter. I will cap of the post opening here the rails were removed. I will cap off my intake air to my WK Gasifier this will dead end the gasifer from the drop box into the gasifer area.
With the hopper that is on there right now I figured about ten to fifteen minutes of travelling time in the Dodge Dakota or may a little longer. I have a temperature probe that will be monitoring the hopper and the cyclone intake.
I need to build a drip water container to drip water into the nozzles intake if to much water goes in it just runs out of the nozzle air intakes. Also I will have my charcoal moisture at about 20% with out water drip. If need I will turn on the drip to prevent and melt down.
Tomorrow morning I just want to see the truck running on the gasifer at idling speed or a little higher rpms.

The Dodge Dakota is running on chargas.

Here is what the hopper looked like when it got down to the nozzles. No heat coming out when opening the lid.

I am really happy with how this double flute charcoal gasifer is running.
I did go to my finer engine grade charcoal fuel when I start the unit this time. I think it was pluging things up a little by the time it got down to the last of the charcoal in the hopper the larger pieces were on the sides. I moved them to the middle and ran the gasifer more after the video. This made a difference on how the engine can rev up. So I thing I will be keeping a multiple size charcoal selection in my mix. The same way I run on wood in the WK Gasifier.

Bet it got really rich, when she stalled out on you; after shooting in the water.

I think a few big pieces of charcoal is good for it, gives the nozzles something to chew on.
From the Gengas book it said the Mako liked anything from dust to 60mm sized char but the prime range was 20-40mm mix iirc. I’ll have to crack open that PDF again.
Edit I think that size range was for the intermediate sized Mako that ran 2-4 liter engines
