[TheForge] simple propane burner question

[GHS]

The number of BTU's per cu ft of gas is
greater with the blue flame. You are
burning closer to 100% of the fuel.

If the yellow flames impinge on the pots
there MAY be better heat transfer, at
least until the pots soot of. Carbon is
a wonderful insulator.

The yellow flames may be producing more
heat if she is upping the flow ate to
create them. (less efficient flame , but
more gas consumption.) 
Then it is just a plain bigger flame.
Why not rig two burners under a pot?
