[Stoves] FW: pot skirt efficiency estimates, scale-up

[Kevin C]

Dear Jed

Crispin has made sopme very good suggestions for improving on the  
"stove aspects" of your still. There is nothing I can add to what  
Crispin suggests.

I might be able to help with operation of the distilling aspects of  
your project.

1: Is it a continuous process or a batch process?
2: What is the volume of "feed wine" that your boiler will hold?
3: What percentage of ethanol do you want in your final distillate product?
4: Do you use a simple condenser, where you simply condense all the  
vapor that is boiled off, or do you use a reflux column?
5: What is the initial alcohol content of the "feed wine?"
6: How many litres per hour of "feed wine" do you wish to process?

I don't understand your separating technology. What is condensed or  
cooled in the "Radiator?" What is the source and  nature of the "waste  
water" that is being sent to the "Waste Water Treatment tanks?"

You would probably benefit from Thermometers at various points in the  
still and condensers. You should also have valves in the water cooling  
pipes, to regulate the flow rate of water from your head tank.

Am I correct in assuming that your "Radiator Assembly" cools your  
condenser or reflux column water flow, to permit re-use? If so, you  
could use a radiator or two (depending on how much heat you have to  
dissipate) from scrapped automobiles for cooling the condenser water  
for re-use.

Your pottery boiler looks great! I presume you are using it, to  
minimize differences in operation from the technology presently being  
employed.

Best wishes,

Kevin Chisholm
