[Gasification] general

[Toby Seiler]

Alan,
   
  Look in the recent archives from this list and find Doug Williams instructions for the downdraft design.  That is clearly a good starting point and will produce relatively tar free gasses for your engine.  It's simple and requires moderate skill to build, operation however requires more vigilance.  I believe Dougs company sells larger units. 
   
  Wood moisture content is probably the most important factor in addition to the fuel size.  To sum up what could be a lengthy discussion, keep your fuel dry and about the size of your fist or slightly smaller.  Since your wood was kiln dried, it should be relatively dry unless sitting out in the weather for a long time. I suggest a covered storage with good venting.
   
  Perhaps I'm different from about 800 or more of the other list members.  This is the only technical list that I subscribe to.  Sometimes keeping up with the reading is difficult when people hit reply and reprint page after page of prior discussion.  I'm not complaining however and appreciate the work that Tom and others do administering it.  
   
  This list has helped very much in my R&D.  While I don't miss Peters rants and US bashing, I do miss some of his thought provoking discussion and references.  And although I don't rank amongst those who are running their gasification systems, the research and understanding that I am accumulating, will eventually be applied.  If one can't understand what is happening inside, making improvements or changes are only a shot in the dark.
   
  I know there are many more advanced participants on this list, with 8-900 on it.  I hope you will help those of us that want to push the fringes and perhaps try new approaches or combinations.
