Gene,
You are correct in thinking something isn't right.
I Fire B-3's and the flame is more clear than blue on propane.
I get a yellow flame ONLY when I cut way back on the primary air.
If nothing is obstructing the air threw the burner. Call Mark
At seven lbs. pressure those Ransoms should be quite loud, are they?
I assume that you have really inspected those burners.
Talk to Mark. Good man.
Good firing

Gene,
Check the primary air adjustment. Sounds like it is very much off the mark.

Gene,
I use two Ransome B-5 at 10psi no secondary regulator in the same size kiln.
I get an extremely long clean flame and the burners do sing as someone
mentioned. The B-5s are a little larger but I use a port opening that is
about 5 1/2" x 7 1/2". Mark Ward did give me a heads up when I was building
the kiln to make sure the burner ports are large enough. I seems to me the
rule of thumb for burner ports is about 1 inch clearance all around and the
burner about 1" back from the port. There are quite a few things that could
account for your problem, true pressure, draft, port size. As suggested,
give Mark a call. He diagnosed a problem I was having in just a few minutes.
Good Luck
Paul
