2x6 arch build

[Chicopee Sap Shack]

it would gasifiy great 1600 in the arch and 800 in the stack but i was loosing my flue pain boil. I ran the air in the door wide open and the AOF wide open but would have to give the grates more to get the boil i wanted. Doing so would push the stack to 1200 ish and keep 1600 or more under the draw off.

Arch worked great prob around 60 gph average. Yes the air in the door shuts off when the door opens but I did not build in nozzles on the front wall and if you don't shut the blower off it will throw fire out the front. I have 1 foot of opening into the flue pan from the fire box. I should have done 2 feet. I can't seem to get full rapid boil in the flue.

You want at least 1/3rd of the length of the flue pan open to the firebox. And the exit to the stack to be the same area as your stack.

So I'm only 6 inches shy of the 1/3 but I don't think that on a 4 foot flue pan that the 1/3 is right. I think next time I would go 1/2 for a bigger burn chamber and more direct flame to the flues. I thought about changing it this year but with an addition and expansion this year I'll wait till next year.

Your best bet would be to see if you can get in contact with 802maple he really knows alot about these rigs. Pretty sure he helped design The Intensofire, he is on the Trader from time to time. I am sure you are headed in the right direction, I think anything above 1300°f you are probably burning some wood gases, any idea what your woods consumption to gallons of syrup was?

I think I'm around 15 gallons per cord

No warping after 2 full seasons. The plate is atleast 3/16 thick with insulation blanket attached on the inside.
