Lanny,
I understand the comment below but I think flame height can be shortened
with excessive excess air. The lowest emissions CO/CO2 and highest
temperatures, at some power levels, in appliances that I have tested has
often been when there is a significantly taller tail of flame.
However, don't believe all tall tails :)

The combustion air needs to be focused on the combustion zone in a way
that shortens the flame height. More like the way a TLUD with a fan works.
