2x6 GPH Capabilities

[Tucker08]

I am in the process of setting up a new 2x6 patriot. This unit has 7.5 inch raised flues with a 4 foot evaporator pan and a 2 foot syrup pan. I am looking to know what the maximum GPH would be with this unit. I know there are a lot of variables, so I will touch on a few.
1) My wood is dry.
2) I have a blower unit and ample stack
3) I will be running it with a pre heater and hood. This is a home made preheater unit, but it is very close to what Leader sells.
4) I know how to load a fire and am a pyro, so the flames will be licking all of the pans and it will be running hot
5) The arch is being set up with arch board insulation and firebrick over the top.

Any insight as to what I can expect? Thanks in advance!

Can't wait for you to get answer Scott... :confused:


I'm looking at a very similar situation/setup potentially!

Too many variables to be accurate. My guess: 30 to 35 if you keep it ripping. Even more is possible with a big blower and super high stack temps, but you would burn a lot of wood. AOF can reduce fuel usage while keeping a high rate but is tricky to set up.

i run a 2x6 split 3x3 and last year i was avg 30 to 35 peaked at 42/43 one night. with you having a 4x2 im gonna have to say you will avg 38 to 43 peaks at 48 maybeeeeeee 50. is it a traditional arch style or new squared up one, is it airtight?

go check out my arch build, leader would prob charge 4k for it if they made one, right now I have around 700 into it.

I can tell you that the number of flues will make a big difference. I went with CDL 2X6 because of this and on my test boil with no blower it was splashing over the pan after 45 minutes.

Thanks. It is a trad Leader arch. Brand new. I was thinking 40 to 45, so at least I am not way off. Attached is a picture when i first moved it into the former bull barn now sugar house.

Thanks.

30 gal will be doing good,perfect weather conditions will up it,boiling at night will also help,Leader puts a lot of research to make your evaporator perform to its abilitly,you also need to fire it every 2-3 min. to keep btu's up,even with dry wood.We put in a new evaporato in 2 yrs ago-3x10.was firing old traditional way,got about 125 gal /hr,called leader and they even came to sugarhouse to show us how to properly boil,now continuely we do 155-165gal/hr just like we were told it would do

Really only one way to find out! :)

[Tucker08]

You got it!

I ‘d have to make a guess right now, but I believe mine has a 42” drop flue and 30” syrup pan. (I know the flue pan is slightly larger, don’t know by exactly how much).

Ran 28~32 GPH consistently without any frills.
Adding the hood and pre-heater this year and expect about 35 GPH average.
Add AOF/AUF and I would expect something a tad over 40.

How many flues in the back pan?

Friend of mine has a Leader raised flue on a tight arch with blower, hood and preheater. He gets just under 50 most of the time. My Mason gets a little over that, but I am putting a lot of air and a lot of wood to it.

Okay I have the same pan setup as you, as well as a hood and preheater. Last year including starting up and shuting down I averaged 43GPH. I had air over fire and under fire and typical internal stack temp was around 1300-1400. Sap from my preheater is usually coming in around 200 this year I built an intensofire arch for my pans and I'm hoping to get closer to 55GPH and use less wood. Good luck
