What you describe is not a TLUD gasifier.  Nor is it a good way to start a
traditional updraft gasifier.

Your limited heat is drying the fuel above it, sending up moisture, not 
woodgas.

I suggest that you do the basic TLUD (if that is what you are wanting) 
operation
in metal cans to see how it works, and then replicate it in the glass for
observing.

Tom Reed has done TLUD experiments in glass tubes.  He reads most of these
messages, so I hope he will comment.

Tom:  The "Subject" of earlier messages was about "Stove Camp 2007" if you are
looking for Frank's earlier description of what he is setting up to do.
