For all the plate variations out there, bubblecap, valved, perforated etc.

Size of boiler to diameter of plate

Postby Tipperaryboy » Fri Feb 28, 2014 1:35 pm

Howdy folks, excuse me if these are silly questions but i just want to ask a few things:

1. im just wondering what diameter of plate would be suitable for a 450gal boiler. Is it linear or exponential. I saw somewhere where a guy had a 100 gallon boiler and was using
12" bubble plates. For a 400 gallon boiler would 12" be ok ? maybe 15"?
2. The distance between the plates for such a large still im wondering about also, I know a lot of it has to do with the heat you can apply and i suppose im assuming this large still size
would be heated with steam. So is there some sort of ratio of plate to height ?
3. For making white rum, would 4 plates be enough ?

No exp. with a boiler of such size but I'm thinking that the shape of the boiler, short and fat v. tall and narrow, as well as the location of the column on the boiler would be a factor in choosing the diameter of the plates/ column.

Doc ?

Hey, thanks for your reply !

Think cylindrical bulk tank size, 450 gallon........jacketed......steam coil heated ! About 1.5 m tall......a domed steel
lid could be put ontop. If you have any suggestions...i was thinking 12inche plates would be ok with about 18 inches between
each plate..........was wondering is there some mathematical formula to consider.

DOC...those are my initials !

Boy do I have a BUNCH of links that may help. The most important thing you need to know is how much available power you will have. Either watts, amps or BTU's. That alone will determine what size column(s) you can run.
I am WAY out of my league here but this is one of the first things I have recently learned. If you intend to design your columns from the ground up I HOPE you have plenty of pencils, and paper. Oh yeah... Lots of available time.
Maybe one of the commercial guys can offer some advice but just to give an example of something I learned tonight... It takes 34,000 BTU's to bring 30 gallons of water to 212*f. You are going to need approx 511,200 BTU's to bring 450 gallons from 70*f to 212*f or 150 kw minimum.

What you asked is in these... It's really not too hard to grasp. Just time consuming, and frustrating if you misplace your notes.
Hopefully someone will have the simple answer. Part XYZ, and you can get one at ABC.
Good Luck!

I may need to be "put down" soon.

Thanks, very much appreciated. Yes, this will be a medium term project and hopefully ill get some help with the fabrication but worth the try.

It's all good! I am really enjoying learning all this.

Fabrication should be the easy part (unless you get a Union guy to help) once you have the numbers worked out.

I may need to be "put down" soon.
