[Stoves] Increasing ND-TLUD riser height accelerates gasification and increases bed temperature

[Julien Winter]

Hi Paul;

I stand corrected.  This is what you said to me a week or so ago.  You were
suggesting a dynamic change.   I have been running static batch runs, and
that colored my thinking.

Paul Anderson:  "About height, whether of riser or of chimney:  I recommend
some simple experiments when your unit is running.   Have some different
lengths of extensions that can be easily placed (not even attached) on top
of the current unit.   The additional draft will pull more secondary air
and make the flame be LOWER as long as there is control over the entry of
primary air.   But if the primary air is free flowing, the primary air will
eventually "catch up" with the increased draft, and the flame will become
higher than before.   If that is not what you observe, please let me know
so I can adjust my thinking."

I will have to give that a go.


Regards,
Julien
