2x6 arch build

[Chicopee Sap Shack]

So I'm starting this a little late but a few weeks ago I started building my new arch. AUF and AOF with air in the door. All fed off a high pressure blower. http://images.tapatalk-cdn.com/15/11/22/c4b0e25236dc4283a2e25d47d743072d.jpghttp://images.tapatalk-cdn.com/15/11/22/64a0c92b909427af347eb4bdae91ca6a.jpghttp://images.tapatalk-cdn.com/15/11/22/21c9f1cd9fbd6c43cb610da3e4dd69f6.jpghttp://images.tapatalk-cdn.com/15/11/22/20cb01a2cb9a41cf6cc655ae9128c2db.jpg

Looking at the shop and the quality of the work I'm guessing its not your first time with a welder. Very nice!

[Chicopee Sap Shack]

Appears to be ceramic blanket. Thats what I use as well.

[sam2145871]

Well how did this work out for you this season?

[Waynehere]

Yes, I would love to hear as well? :) Did you have enough sap to keep up with your new arch?

It looks like you setup the door to shut off the air when it opens? How did that work for you? Any changes you would have done after your first season?

Very nice looking rig. How much of your sap pan is exposed to the firebox? I am building one this summer and was thinking of exposing at least half of my 2x4 sap pan to the firebox on my 2x6 setup.

[Chicopee Sap Shack]

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 pan

I would say if you are trying to gasifiy you did well at 60gph average. What were your load times. How much syrup per cord of wood? That's just as important as GPH.

Is there a way of extending it to 2ft, I know it would involve a bit of work, but the payoff might be well worth the effort. Liking the set up you've put together, it's on the top of the list before next season is to get my boil rate up with a rebuild.

[Waynehere]

Hey, good to hear with 60 gph. Although Nate bring up a good point too. I was getting 45 gph, firing every 10 mins. I got about 8 gal per face cord. Not the best and working on changing that... I was talking to another producer on here and he wasn't happy with the nozzles on the front wall as well. Said he was going to build another arch without them this time. I was thinking of nozzles on the door and down the sides, and be able to control both on separate controls.

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.

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.

[Chicopee Sap Shack]

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?

[Chicopee Sap Shack]

I think I'm around 15 gallons per cord

I know this is an older thread, but none of the pictures show up. Any help would be appreciated

Mol, any warping on your stack plate and how thick is it? Thanks.

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