Greetings Billy, and list members.
In most designs of "homemade" downdraft gasifiers, IMO the feedstock can
only push moisture content to the area of about 15%, however, if an "air
dryer" is used in the tuyere air, 18% is attainable.
Why I say the above, is that on the opposite side of things, having too
little moisture will cause an excess clinkering due to the gasifier running
In your case a simple water injector system could be used to temper the
overall reaction temperature, AND it kept at the high-end of reaction, could
also employ the water/gas shift just above the reduction zone. this would
have to be carefully managed, but could be done.
Most gasifiers suffer from a massive excess's of moisture, my personal
observations are that 4-9% is ideal for most feedstocks total moisture (air
and feedstock combined).
hope this helps.
