Dear Bill
Quoting Bill Klein <[email protected]>:
To underscore Greg's email, repeating what I was taught, "The
quality of the gas is in direct proportion to the quality of the
char." Larger feedstock makes great char!
# OK!! Do you think one can make "Engine Grade Gas" using:
1: Wood pellets, 1/4" diameter, 1/4" to 1/2" long?
2: Wood chips screened to -1/4", +1/8"?
3: Wood chips screened to -1/2",+ 1/4"?
4: Wood chips screened to -1", + 1/2"?
Thanks!
Kevin
Respectfully,
Bill Klein

10K gasifier?
Pete, (and list)
What, and how big, are the fuel chunks ?
most gasifiers do NOT like wood chips, or really "fine" fuel, the
interstitial space the gasifier is designed to run with, is
generally much larger than that of chips or fine feedstock, using
the correct sized fuel, in-turn, lowers the reaction core
temperature, thus creating more, and more consistant amounts, of CO.
(the main flamable gas, in woodgas). (H2 and CH4 are simply "bonus"
gases.....)

Has anyone here had any experience running an engine using the

They tell me that the JXQ-10 gasifier is a forerunner to this
machine. I have one of those. I?d like to be able to correspond
with others who have this style of machine. Currently I am having
mixed results getting a steady flow of good gas to run my 6.5 KW
Onan 1800 rpm genset from it. On Saturday, I got it to deliver
about 3.8 kw for about 12 minutes, but then the quality of the gas
deteriorated. On Sunday a similar test produced worse results, but
over about a one hour period, with gas quality again deteriorating
as the test went proceded.
I am not writing to waste the time of senior members here by
asking them to troubleshoot my problems, without enough info. Just
want to show what kind of issues I have for those who might be
involved with similar equipment.
My goals are to: 1. See how much power I can squeeze out of
the generator for an extended period of time with this gas source,
and 2. To get some actual experience making woodgas.
Looking back over my videos and notes, I can see a dozen or two
things that I could do better next time.
