Howdy All
We are currently building the unit needed to power internal combustion engines on wood.
You can watch our progress in researching and building the wood gasifier at
http://primus.drclue.net/Power/WoodGas/index.php
The most complete instructions on the site relate to the downdraft gasifier
outlined in FEMA documents , but the one we are actually building is a
cross-draft version.
I've re-done the FEMA drawing , correcting some of it's errors and
at the same time I've rendered companion drawings to have coverage
for updraft , downdraft and side draft versions.
As things move forward , I'll be giving details on how and why it works ,
so that one can more readily adapt the information to whatever materials
you have laying about.
There is really only one item for which the measurements are somewhat critical
( The burn tube ) and I have charts detailing the dimensions required for various
horsepower/displacement requirements.
If your reasonably handy (which most bus people tend to be ) then this
project should be a reasonable undertaking.
