Dean,
Just another note. There are high temperature stoppers that will go to
230 deg. C. If this can be used it will be easy to punch holes in it. I
am thinking two small holes with 1/8th inch tubing for both the primary
and secondary air. Make two small holes for copper wire that goes to the
bottom and attached to 'toaster' wire to start the fire(using dried
grass?). Then a larger hole in the center with ceramic tube that goes
through the stopper for the flame. All this thinking the heat will not
travel down the ceramic tube or up the glass to be too hot for the
stopper. If it gets too hot we may need to replace the stopper after
each run.
So the immediate questions I have are what size flow meters should I get
to regulate the primary and secondary flow with this size shell and how
should the ceramic tube be constructed? Does it need a burner with holes
on top or can the flame be just lite as it comes out of the pipe? and
will this design work?
Thanks for any suggestions
