[Gasification] Wet wood/green wood debate...

"The wet/green/dry wood debate really got me thinking."

I don't think it's really a debate. Just a suggestion to consider the
possibility of using high MC fuel. At least from from my viewpoint.

One of the problems, as I see it is that specific results using specific
test setups lead to generalized conclusions, which may or may not hold
water. So to speak. This doesn't apply just to high MC combustion, but to
the whole range of combustion inquiry.

For instance, the statement that high moisture content reduces temperature
by 200C must be a very qualified condition. I'm sure it could reduce some
other setup's reaction by 400C -- or even extinguish it for that matter. I
can imagine it actually raising another reaction's temperature. What
temperature was the steam injected at? If you change the temperature of the
steam, does the temperature of the reaction change? Does the contribution of
steam occur somewhere in the process where reaction would be a benefit to
complete combustion? Is it injected where it would be a detriment? What is
the reaction sequence of the combustion? The timing? etc. etc.

If we generalize, we create limits for our thinking. We create rules which
prevent us from considering other possibilities.

It's important to be very specific and say, under these special
circumstances, in this special setup, doing this action, we observed this
result.
