It's possible to dry wood with steam. I have a colleague who built a commercial steam dryer in a 20' shipping container. It was being used to dry firewood.
I would imagine that if you blast any wood fuel with superheated nitrogen/steam mix from an engine exhaust at 400-700C then the net effect will be to first drive off the water vapour and then begin to torrefy the fuel. I'll try to get some more details. Ken _______________________________________________ The Gasification list has moved to [email protected] - please update your email contacts to reflect the change.
