Using the energy of condensation might help raising the ABV of the output, because the condensation at the same time causes a higher ABV in the thumper. But when the primary boiler is emptied, heating the thumper might shorten the tails. Rather than steam distilling. (Of course you have to keep the boiler on steam too.)
You have my attention, for I have to preheat the load of the primary boiler and out of habit I did the same with the load of the thumper.Pikey wrote:If you bear in mind that chart which skow conveniently posted, The higher the temperature in the thumper, the lower the abv of the charge needs to be to distill and the lower the resultant condensateEdit: will be.
Now we already know that the longer we can delay the thumper reaching boiling point, the higher the abv of the charge will be, and again from that chart, the higher the resultant condensate will be, so I cannot see any reason why we would want to hurry that process up. Surely the colder the thumper starts the betterEdit: ?
Next opportunity I will note the difference between preheating or not the load of the thumper.
