6" Flute on a 26 gallon boiler??

[vagabondmountainman]

I've been running a 4 inch flute on a 26 gallon boiler for a little over a year now and am thinking about moving up to a 6 inch to save time on runs. I'm not sure if there's enough alcohol in a 20 gallon 8-10% wash for a 6 inch flute. Doing 20-22 gallon runs of bourbon and scotch on the 4 inch, if I run nice and slow in the sweet spot usually takes me 7-9 hours a run which is fine, but it would be nice to be able to distill a batch off in 1/2 the time and get in a run after work now and then. I haven't been able to find much on the threads regarding minimum boiler size for a 6 incher though since most hobbyists run 3 or 4 inch flutes. Thanks in advance if anyone can answer my question.
