[Gasification] Running a vehicle on wood gas

[Peter Davies]

Thanks Paul, yes it is. The 1988 visit to Canberra was when my Father in 
law was involved. What I find interesting is that it worked well enough 
in its own fashion and achieving the aims of the people involved, so 
what could be done with say a modern 60hp unit... I understood the tar 
from the Gidgee (and other acacias) that people here in Oz talk about to 
be in the first instance a natural feature of the tree, a resin/sap 
exuded in noticeable quantities out of the cut ends when heated,  this 
is particularly noticeable in the drying phase inside a gasifier like 
the Imbert and can cause bridging through "sticking" up the pieces so to 
speak, though I would also defer to Doug's explanation and superior 
knowledge regarding the piece sizes used for the system in the article. 
We have found acacias to be an excellent gasifier fuel ourselves and 
gave the highest fixed carbon results in independent tests of our system 
conducted by Greening Australia, being 93%.

Wood pellets have been slow to develop here in Australia mainly due to 
industry factors and trying to get ultra high returns, and so where 
available are not cheap as for the US, more like $750-$1000/tonne, this 
could change shortly. Also you can buy cheap 50-100kg/hr flat die pellet 
mills from China which might be adequate to make your own fuel, quite 
apart from using straight wood chip or docks for shorter runs.
