[Gasification] Gasifier Automation Schematics & Circuitry Package

[Fredrik Ek]

Greg,

I´m interested in your automation system as well, the price is no problem if the
thing works and if I can implement it into one of my gasifiers. Can you send me
a bigger version of the scheme you posted? It is as such not readable.

Have you already got the filter material samples? 

If you are going to feed wood chips within a 4" pipe, what is the size of the
chips you use?

I built one and a half years ago fed by a 125 mm 5" screw in a standard
Ala-talkkari wood chips feeding system, this screw anyway smashed my nice Kopo
conical screw chips into sticks. Because of this I abandoned this screw for
feeding a stationary gasifier. Bigger screws work, or I use to think that the
screw should be at least four times the diameter of the size of the average
chips to work properly.

This I tried without success.
