I posted a thread similair to this a couple months back in the DIY section but didnt get much feed back. I'm still having issues with this so I wanted to see if anybody has any more thoughts.
My all grain stand uses 3 10" Banjo Low Pressure burners purchased from Brewers Hardware. I also have 12" heat shields, 3 propane orifices, and an 11" WC propane regulator. You can see everything on this page: Brewers_Hardware
No matter what I do I can not get a good flame off of this burner. It starts off nice and blue but after about 15 minutes or so, the flame turns bright orange, licks up the sides of my pot, and puts black soot on everything. As my palate for off flavors improves I'm starting to notice what I think to be DMS. My boils have always been more of a simmer (11 gallon batches).
I have the vent on the burner open as wide as it can go. I've tried lowering the burner, raising the burner, less propane, more propane, everything I can think of yet nothing gets me that nice blue, high intensity flame I am looking for.
I never run more than 2 burners at a time. But even with 1 burner running I cant get a nice flame.
I am looking for any and all suggestions, stories, similarites, that could help me fix this.
Thanks for any and all input!
