Hey Tone. What does the Kruster1972 on you video mean. If the 1972 is your birth year then I have two daughters older than you. Now I really feel old. Say it isn’t so.
What Wayne and J-O said, big smile
Tom, if you have daughters older than me, you were really hardworking in your early youth (of course your wife too),…
Not a lot of hard work involved Tone. Of course if I had a time machine I’m pretty sure I’d go back and get the snip job.
Tom, you don’t want to go back, think, with the good things come the hard ones, you’ve done and survived so far, I don’t want to go through all that anymore, this time that is now is the best for all of us, just don’t we can waste it.
330 hours on wood
Today I cleaned the gasifier, “regular service after 50 operating hours”, I turned it upside down and emptied the contents, you can see that there were quite a few minerals among the charcoal.
we talked about the weight of the gasifier, and I weighed it
a look inside, no damage so far
70 kilos, amazing job Tone. I knew it was light but not that light!
You looked good on Camera, it was nice to see your big bright smile, but I could see on the video, you and Fergie were running as fast as you could to get away from the camera. The things I noticed was it was actually quite beautiful countryside. You didn’t take the turn with the stop sign. And while in the middle of the intersection with the orange tractor, you weren’t paying attention to the road, you were trying to figure out how you were going to gasify it.
Hi Tone
Do you think that your gasifier, with several levels of nozzles, works at a lower temperature than the gasifiers with a single ring of nozzles (without small central nozzle)?
I want to talk about the temperature at the level of the two rings of nozzles. At the height of the small central nozzle, I suppose that there is only charcoal left and the temperatures there are very high
Hi Trigaux, I believe that the temperature between the glowing charcoal is very high in any gasifier that works well, regardless of the arrangement of the air nozzles, I tried with my arrangement to achieve only a wide range of stable operation, from low to high load. At low load, very high temperatures are distributed around the barrel nozzle, but when gas consumption increases, the glowing temperature spreads upwards, as the engine vacuum pulls the gas from the upper part and also the air through the higher nozzles. The difference in vacuum between the levels is created by the diameter of the hot zone pipe and the material it is filled with (fine coal mixed with ash), above I posted a picture of the material I emptied from the gasifier, here you can also see the clinker that is produced from the molten ash. even in the area of the highest installed nozzles, a hard crust of ash similar to concrete was formed, which means that it was also hellishly hot here.
in your gasifier, I imagine that the numerous nozzles, placed at different heights, inject air into a large volume of fuel vs. into an Imbert. few nozzles in a small volume of fuel. I therefore deduce that the energy released by the oxidation of the fuel distributed in a large volume reaches lower temperatures than in a small volume.
I hope I am understandable. it’s difficult to explain my understanding of things, English is not my mother tongue
ThierryT. reading understanding TONE’s explianations it is very important to realize he is working with variable speed, and loaded IC engines.
His gasifier internal jets draws vary; because of these engine driven needs.
He only blower-fans from cold for gasifier starting-up, heating-up.
So his has NO corospondnece to LAB-Rat purely electric blower system results.
So just like on a purely mechanical liquid fuel gasoline carburetor; or a purely mechanical LPG/propane mixer the varying pulled engine sucking draws will bias different flows from different mixer jets and orifaces.
But as a solid fueled system it’s own internal changing levels of resistance to flow; and effects of desired outgassing in each gassers Internal levels will also affect jets levels flows.
His truly now is an advanced many stages carburetor.

Its not how it works unfortunaly. The ratio between air and gas output is rather constant, no matter the design. Chemistry doesent lie, it takes a number of molecules to react with a number of molecules. But what we can do is spread those air molecules trugh the hearth. Imbert dumps them all “fast and furious”, Mr Waynes pours them in gently, multi nozzle level style gasifier (as is Tones, JOs, myne early tryes, Arvids…) do them on multiple levels. Each had its pros and cons, but most of all its important to tailor the design based on the needs, and FUEL.
People continue to not understand the basic principles of how Tone’s system of nozzles works. We must first understand Bernoulli effect.
The small brass device in the middle of this assembly is a vacuum generator that uses Bernoulli effect. When I put air pressure in one end I get vacuum out of the other end. This is much like the arrangement of Tone’s lower grate nozzle. But Tone’s nozzles are not designed for making strong vacuum. They make only weak vacuum. However, when the hearth becomes restricted air flow to the upper nozzles is reduced. This forces the lower grate nozzle to reverse flow, just as if I had covered the exhaust ports of the vacuum generator with my fingers.
Tone’s nozzle system creates a dynamic balance of air flows between the lower nozzles and the upper ones. Ask me any questions.

Mr. Wayne once wrote, “when you drive on wood gas, your tires wear out”, but I say when you have a tractor on wood gas, you will have your hands up to your knees, work,… work,…
I recorded this the day before yesterday, nothing surprising, just a standard procedure, well, I blew the gasifier a little too briefly before starting,…
Mr Tone, you have way to much fun
Your tractor is amazing
Tone, your Fergie sure runs sweat.
Looks like an airplane cockpit with all the buttons and levers
And Tone like a mad sciencetist actualy knowing what they are for
Since I’m making silent movies like Charlie Chaplin, I’ll add some more subtitles:
- the tractor worked for about half an hour, until I reached the forest, where I was sawing and loading wood, this lasted for 3 hours, in the meantime I occasionally open the lid to keep the fire alive
- when starting, I first blow air on the nozzles while the chimney is open, so a larger part of the water vapor comes up and does not cool the heart with charcoal
- then I close the chimney and wait until I get combustible gas, install the gas pipe on the filter, which is filled with gas, then turn off the blower and install the pipe from the filter on the gas mixer
- when starting the engine, I set the air flap (the lever I turn) to a fairly closed position, the lower lever (the lever from the bike gearbox), to set the centrifugal regulator, I set it to low speed and the upper throttle lever to 1/4 opening.
- the gas is bad at the beginning and a bit moist, if the engine inhales a full amount of such a mixture, it does not ignite, probably due to high compression and moisture, so I try to adjust the levers so that the cylinders are only partially filled with the mixture, which allows ignition
- while I adjust the levers and try to start the engine, the steam presses down into the hot zone and cools it down, and the gas becomes very bad, so it occasionally happens that after a successful start the engine shuts down again and the process has to be repeated
Yeah, that’s a critical moment right there. We should have a special word for it. It’s related to hesitation, but not quite. Suggestions anyone?
Since I also have a loose fit blower it’s about hurry up between blower shutdown and cranking. Plug the outlet, store away the blower and walk around to the driver’s seat for cranking is sometimes too many seconds to maintain enough heat if it’s the first start of the day. Also, this is the moment when wife usually takes the oppertunity to call me away or wants me to focus on something else
With the fuel injection it’s easier and more wife friendly to just take off, let the stored gas run out and add a few short clicks on the fuelpump switch to overcome bogging down.
