My homemade hoods utilized a drip tray under the stack that also held a pre-heater. My current one is a commercially made hood, it has a very wide, rather shallow funnel which is suspended from the stack. My stacks are 15" on both the flue pan and the syrup pan hoods and those funnels are about 19" OD. They are maybe 3" tall and an elbow exits the bottom of each. From there each has a channel hung from the elbow that carries the condensate to the nearest drain gutter in the hood. When my evaporator is at full boil those funnels catch a solid stream of condensation continually, with the flue pan hood flowing far faster than the syrup pan one.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
