    Default barrel stove evaporator

    I currently have a barrel stove evaporator and was wondering if anyone has put any kind of baffle or something like that to help keep more heat in.

    I had a baffle in the stove pipe. Didn't help much (at all?).

    Air under fire had a much larger effect (and a reverse osmosis system).

    Is the barrel lined with a ceramic blanket, and bricked?

    No it's not lined but will have fire brick going up the sides this year. Last year it just had sand in the bottom.

    One of the best moves i made on my barrel evap was putting insulating blanket between the fire brick and the wall. I did have baffels on mine. The front half was the firebox and the back half was a shelf to get the fire closer to the pan. I put the baffles in the back half so that the flue gasses had to go left then right then left... etc. Cooled the stack down a lot.

    Do I need the rigidizer for the ceramic blankets? For the amount that I would think I would need there would be a lot left over and wasted.

    I did blanket and brick in my barrel stove. I did a test boil but haven't gave it a season to run yet. Sides were warm but not hot. Didn't mess around with flue temp or baffles. I did have a fan up front under the fire but it didnt seem to change boil much. I think i need more Firebox/less grating. Might move the wall back a few inches after this year. We will see how it goes. I was able to boil in my test run. Smaller chunks of wood are needed too. I made a square pan to sit on top instead of the buffet pans.Screenshot_20171207-185713.jpg

    Did a test fire tonight. Steve- you add your bricks and test fire? My 50 cfm exhaust fan makes a good bit of difference once I have a decent set of coals. The damper which came in the barrel stove kit also helps immensely.
