Hi all,
I recently upgraded my SP10 burner to a BG14, both on natural gas. I was unhappy with my propane tank emptying on the SP10 so I converted it, expecting a BTU drop- I got one. That burner couldn't heat 6.3 gallons from mash/ sparge temps to 170 degrees over a half hour so I moved inside and did a stove-top boil. That day I bought the BG14 (same burner that's in a KAB4, but without the stand). It's now mounted to this stand using 1x3/16" cold-rolled steel:
These photos are wide-open both on the ball valve and the air control disc. They are also in the garage with the door mostly closed (it was only running for 2 minutes, no worries) to keep it fairly dark.
The second shot is looking up with a 5 gallon SS pot. The flames are less than an inch high, nowhere near touching the pot.
From the top of the burner to the bottom of the pot is 3.75", and the burner top is about equal with the 'skirt' around the stand. Currently the orifice is drilled to 7/64". I'm hesitant to go larger because I'm not experienced in how the flame should look. We're at 680' elevation and my meter doesn't have a gas pressure listed. I assume it's the standard 5-7" w.c.
Does anyone have a recommendation on getting more NG output, or is that the flame I should be seeing? If this is proper that's okay- I just don't want to be missing out on more power. I heated 4.5 gallons from 63 to 163 in 31 minutes yesterday as a test. It was 61 degrees outside at the time, little wind.
Thanks! Kyle
