Robert,
I thought Bruce was asking how much water is in the engine exhaust after it is
running on producer gas. I believe he is wanting to dry wood fuel by directly
introducing IC exhaust into a stock of wood fuel... but could be mistaken.
For the most part, the producer gas he is beginning with, pre-engine, is
perhaps 50% nitrogen, 27% carbon monoxide, 14% hydrogen, 4% carbon dioxide, 3%
methane, 2%oxygen (wiki). Maybe he is doing better in hydrogen and reducing
N... I don't know. It seems the 50% nitrogen continues and the 27% CO would
make CO2, leaving the 14% Hydrogen to become H2O (vapor).
Also one must "follow the heat". It takes about 1000 btu to make liquid
water at 212f to go to vapor (drying wood must go liquid to vapor). Where is
that much heat coming from?
In direct introduction I think the wood will have condensate on it, not dry it
out. It will raise the temperature, but not make it dry. Of course it is all
relative to the amount of wood one is drying. If you gasify 10 lbs and dry
one, it hardly seems there is an advantage, although possible.
