Well folks I have been working on this project for a while and thanks
to many of you on here I have come up with a Semi-Automatic single tier 3 keg propane system based primarily off of the designs from jlandin, nicksteck, AGBrewer, Yuri_Rage, Bobby_M, Lonnie McAllister and many others at this time have slipped my mind
Please take a look at the photos below (let me know if they are viewable). I am running into a problem however involving my burners. Here is my current setup
Propane Tank--> 3/8 OD line to a Marshall 290 dual stage reg
---> Gas manifold-->HLT & MLT via Honeywell Furnace Valves
(with proper propane spring installed)--->3/8 ID custom hoses from Hecht Rubber
& for the Boil Burner I just connected the BG-14 to the same 11" W.C. gas manifold for manual operation.
So as I learned from all of you pioneers on HBT, I drilled out my original high pressure BG-14 orifices to 1/16" to allow the 11" W.C. propane gas proper flow into the burner, and as you will see from my pictures I get a nice blue flame that is clean and about 2 1/2" to 3" high.
My issues is with the performance of the burners
I use Beer Tools Pro and when I do the calibration for my burners and measure how long it takes any one of the burners to give me an 18 degree delta on 10 gal of water it takes at least 11 minutes! Which is like 2.94 Kw, not what I was expecting, especially after reading all the great things from jlandin's
project. And it literally took over an hour to heat HLT water from 68f to 180f. I didn't even bother trying to attempt a boil with the BK burner, I just resorted to using my original Bayou Classic Turkey Fryer Burner which get me boiling in less than 20
So I realize by going to a low pressure semi auto system I would be sacrificing some performance, however what I have now literally would take me 3 days to do a single 10 gal batch!
So from the research I have done I need to do one of the following:
Increase the size of the supply hose from my LP tank from the current 3/8 od (1/4 id) that feeds my Marshall 290 to something larger like 3/8 or even 1/2?
Drill out my orifaces larger or purchase these LPG Valve-Orifice
Unless of course my current configuration is correct and I am stuck with a crappy heat txfr from my BG-14's to my kegs?
Any advice, recommendations, or verbal abuse
