I agree with both points of view, in ways, both Rindert and Kristijan. The downdraft design forces the steam to pass through the glowing char, largely addressing the concern of exposing H2O to cracking temperatures.
But, at shut down the effect of heat producing steam will take over, leading to condensation in the system, and drying of the fuel. Also, if steam production was excessive in operation I might imagine it making “wormholes” through the char bed, avoiding cracking.
The only ways I see to avoid these problems would be “just in time” feeding of damp char, impossible to achieve without advanced sensing, or avoiding damp char, introducing steam as in the steam cooled nozzle designs, or a water metering carburetor, as suggested by Max, @gasman.
Great progress and innovation in design anyways, as has been said, probably the most compact gasifier to ever run a passenger vehicle. Once the bugs are worked out it will be a marvel.
I’m kind of with JO. I know when working with wood gasifying, we are looking at a bunch more of water but once the wood gets to the oxidation zone it is char coal. That char goes through the reduction zone pretty much like in a CC gasifier. Yet all through our cooling system we condense water. Why isn’t it possible in a CC gasifier to have hot gas carry water? You are not cooling the gas by running back through the charcoal, like a Simplefier gasifier. You are running through cooling pipes like a wood gasifier. ( I never did understand chemical stuff, so I approach this from a mechanical view point. ) TomC
excuse me Kristijan to use your page to ask a personal question. I am building a gylmore style to feed my toyota pickup. I want to be able to keep, if necessary, the conduit to gasoline.
is it necessary to seal the gas line just upstream of the mixer? or close intake of the gasifier could suffice?
Hi Kristijan, Dave& Brian and other that where wondering about me.
Thank’s for your concern!!! I am still alive, you will not get rid of me so easy, ha ha!! I paused my activity on this forum because I want to finish my truck before I update with you. I am still working on my truck: Rebuilt the entire engine, clutch, electrical, breaking system, carburetor, radiator, fuel system, chassis A LOT, instruments, starter, alternator, driving system, steering system, suspension, water pump, air filter, now I am dealing with the gear box (hopefully my last item). But each time I think that I am almost there to start with the chargas, something new comes up…more than once I thought about taking my truck to a priest for exorcism it !! Sure I have spend more money that what the entire truck worth it, but my main goal is not commercial, but to drive on chargas some day, hope soon.
Besides I are tangled up with other duties.
I am still available for the drawings of your system, (please sent it to me in private because I am not entering into this forum yet) and will work on it.
Hope all are doing fine.
Truly yours.

Eddy,
I rebuilt a 1962 Ford Fairlaine once. And I learned that it never makes economic sense to rebuild vehicles. But I learned a lot, so that made it worth it. Now I have a 1991 Ford Ranger, with more than 300K miles. Both the engine and transmission need to be rebuilt. Part of me wants to do it. But I will not. When it dies I’ll just get another old truck.

Hi Krisitijan,
I followed you progress also I didn’t write for a long time. I’m again very impressed by you speed and design!
Hats off!
I would love to see a video of the operation, with lighting from cold. So please, if you can find some time for this, I would be very happy.
Keep on with his fantastic work!

Fantastic job of compacting everything so that the system is stealth. I can’t wait for Eddy’s drawing. I have followed your build, but time lapse between postings is hard for me to comprehend the total system. I was particularly impresses with your pressure gauge ( manometer ) I had a long board sitting on the floor up against the dash, with a pint jar full of water. The way you think of things and ways to do them is just amazing. TomC
Well l planed to finish the system this week and do a drive video but l caught a real bad tosilitis so outside work is not the best idea.
Thierry, yes, l was planing to make it my self but with the hopper pressure guage l am not sure l need it any more.
Don, good eyes! Those old tools are just for show now but they were used dayly not too long ago. Oxes and horses were the tractors for decades still in post war Slovenia.
Yes it is. However l think this particupar one was used for training of the young animals.
Wery frustrating couple of weeks. I had wery crapy performance, the engine barely sustained a idle on chargas. I had everything apart multiple times just culdnt find the problem. Well it seems it was all becouse the felt sack filter got plugged. Wich is weird since l tested it with my breath blowing in and it seemd fine, looks like l was wrong.
Anyway, drives strong again now!
Edit: l wore the DOW shirt on the trip today and this has no dubt helped to save the woodgas problem
