[Gasification] Power Pallet

[stuart mather]

Has anybody heard of a small scale rotating drum retort approach to pyrolysing sawdust, rice husks etc? It seems to me it would eliminate the problem of uneven heating. Come to think of it i'ts probably the way to ensure even pyrolysis of woodchips too. Whole carcass spit roaster turners are readily available, so the engineering doesn't seem that difficult.The exhaust gas vent could be at the center of rotation at the other end of the drum to the drive mechanism. Insulating the rotating retort might be a challenge though.
Stuart.

If you haven’t already done so,  go to this page:
http://gekgasifier.com/faq/
You will note that sawdust, even pelletized, only gets a fair reading.
Same as rice husks.
  I don’t use any wood pellets, but an acquaintance who has used them says they can turn to mush when they get hot.

Steven,
That’s a good observation. But how are rice husks gasified? TLUD only? Thin fuel bed?
Thanks!
Mark

Andrew,
 
Your fuel would need to be pelletized.  Gasification requires air flow through the fuel and sawdust is too fine.

Hullo all,
I am looking for an off grid power supply, and came across this power pallet from the US. 
http://gekgasifier.com/gasification-store/gasifier-genset-skids/
 
Does anyone have any hands on experience with these? Are they as good as their web site claims? I have easy access to abundant hardwood sawdust and shavings from a local timber mill, and would like to set this, or a similar unit up on a continuous feed arrangement. Any suggestions there anyone?
 
Many thanks
Andrew
