barrel stove evaporator

[crowellsr]

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).

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

[crowellsr]

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 just used the blankets.

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.16948

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.
