- Sep 30, 2004Brad,
Well .... I have generated lots of information....
I have a large pump, so head is not a problem..... I can pump 20 gal per
min at 10 ft
From the answers here, I have decided to get a larger tank, probably a
50 gal plastic drum, they are $8 locally
I have an aircooled condenser from a window air conditioning unit with a
fan blowing through it and I can do the plastic bottles of ice....that
should take care of the condenser.... I have not seen anyone say what
the max temp of the condenser water should be but I suspect anything
less than 35 to 40 deg C should do it....? (correct me if I am wrong in
my assumption) .and I know that the condenser will require
significantly less heat transfer when condensing alcohol than when
condensing water ....
I have built a forced reflux addition and I will probably use house
water and run it to waste and not recirculate it.... for that because I
found out that the forced reflux column releases a lot more heat than
the condenser... ( I have done 2 runs with just water in the boiler to
I have a bucket of wash bubbling and when I run it through I will post
pics and information...
I have built everything from information on this forum and I have made a
few "interesting changes" of my own that I will share....
