I need help on calculating the surface area required for copper internal heating pipes in a 3000ltr / 800 gallon wash still design I'm working on. The pot size will be <>2000mm/1200mm - 79"/47".
I'm thinking circulating thermal oil instead of steam as the easiest option for heating the still.
My understanding is thermal oil runs at about 300C / 572F, with the oil being pumped through an open system (zero pressure) via a header tank. The heating side will be gas fired.
Agitation will be part of the design equation, any thoughts welcome.
