Hi, Kristijan! Good day! Soon noon!
31.5.2017
On the same height, a plank uses ~2/3 of the plate surface that a corresponding cylinder uses! That suffices.
No direct losses; all heat has to go “through” the fuel first.
And you don’t have a “gas-hot” outer surface to worry about!
Especially in a “hidden” solution…
A long-cord thermometer is enough to begin with, and manual “flapping”…

I guess air preheat wuld be hard and inefficiant in such a sistem, as most energyid used to heat the fuel. But is it eaven neaded with haveing super dry wood (negative water content)?
The plate might be problematic for bridgeing?

Hi, Kristijan!
31.5.2017
Air heating is good to arrange around the hearth, silo preheat starts at the silo funnel.
Air heating first, then silo heating in the center of the silo.
One does not exclude the other, they come in series.
And decent cool silowalls… in the beginning. Its under work.
Well, you don’t get perfect wood in every place, but with a well equipped gasifier you will overcome the most usual inconveniences.
To me an easy cleanable air preheater is harder to design than the plank. Vertical tubes manteled around the hearth is the current concept. Gas in vertical tubes, air around.
Sounds like the steam went out of you, rare!

“Sounds like the steam went out of you, rare!”
Ha! It hasnt yet begun to boil 😋
So, with center out heating, and WK tubes out, one culd insulate the hopper. Good for a inkognito gasifier.

Thank you Tony! Welcome to the site!

Keep your feet on the ground! The upper hearth and the large reduction volume work nicely in balance, but it is still a cool-air imbert-like construction.
The upper hearth is 5% of the “Sekundenverbrauch”, as the Germans would say. Meaning net gas consuption/s at WOT on open road = 3300 RPM
The small upper hearth maintains a good process temperature in sloppy town trafik. Only 4 nozzles gives good penetration to the center.
But you need a twin barrel arrangement to accomodate a useful gas filtration. (if doing it hot)
Between the gasifier and the filter barrel you need a cyclone to scale off 90% of the soot into a convenient detachable big pot. This is a practical way to handle the daily coarse routine. (With clean hands!)
Plans to build, or study first?

High, Tony!
22.6.2017
There you go! The library on this site has a lot of good books!
To me, Kristijans “flora” of troubles is a very good asortment of things that has to be solved; as one thing seems to be OK, the next appears!
This is the hard way of learning, but the yeald is fantastic for all who are following it closely.
And you see, that many others share similar experiences, or the same.

Hi, Kristijan!
22.6.2017
Your energetic way of developing new solutions and applications has brought about a lively discussion stimulating new ideas almost every week…
A lively correspondence even among the “big motor” builders has come about.
Everyone appreciates this lively experimenting!

Hi, Kristijan!
23.6.2017
Here people go out to the coastal islets, skerries in the Archipelagoes and at inland lakes and islets too. Having bonfires troughout the night, drinking, singing, dancing. To my place it is ~276,1km/152.5 mi
on the road, to the nearest reachable Mainland point.
Cheers!

Happy Midsummer!
Kristijan, I always thoguht celebrating Midsummer was only a Norse infidel/pagan tradition. Early potatoes, raw herring and snaps here.
