2x8 oil conversion

[Windy Acres]

Looking for some input/ measurements, we are going to convert our A&A 2x8 to oil for next season, I'm looking for how far it should be below the pans, how far the tube should extend into the firebox, nozzle size, pressure, changes to firebox, etc., thanks in advance!

Father and Son has a 2 x 8 oil he might be able to give you some numbers.

Without looking, on the inside I’m pretty sure the gun is flush with the ceramic blanket but the diverter ring sticks past the blanket.
I will go out tomorrow and measure how far the gun is below the top of the arch

Same on mine. How far I dont remember but could check on the next pan turn

Ok thanks guys!

[Father & Son]

Here’s the pictures of the gun placement. The center of the gun is 10” from the top of the arch.
They are a little blurry, sorry.

Thank you, and how's the ramp inside the arch, a wall or a steep ramp, and how much of the flues are exposed?

[Sugarmaker]

I just happen to have a picture of Jims rig. Its not a great picture of the side. Looks like some ramp.

Windy Acres,
I was told when you are setting up a ramp it should come up at the 1/3 distance on the flue pan.
5ft = 60”, 1/3 of 60 is 20” back on the flue pan.

Looks great! What do you get for gph?

[Father & Son]

I was expecting better. Was just a little better than 50 gph. One of my issues the flue pan is 15 years old, the newer pans with taller flues get a better rate. Also, this summer I’m going to have the burner checked and adjusted to try to improve the boil.

[Mead Maple]

50 is good as far as Im concerned. I am only getting 30 with mine but its very early in my homemade setup. Hoping to get things dialed in over the course of the next season

I guess what I should have asked is if we get a little over 80 now, can I expect the same performance with oil?

[Father & Son]

I was always told it would increase because it’s a constant heat as compared to opening and closing the doors to fire. But with all the additions to your arch I guess time will tell. That’s why this summer I’m going to see if mine can be fine tuned for improved efficiency.

[Mead Maple]

From what Ive been told, in order to get the same GPH out of oil you would have to send a lot of heat (fuel) out the stack. You definitely notice the constant burn with oil and lack of opening door and losing heat by firing with wood. The catch with oil is you would need to mimic the amount of flame you had with wood which usually means a fair amount of fuel

Yup, I'm sure the consistency of oil will be right there with wood, without the lulls, I know we would try not to fire when we were close to a draw, and we usually get a draw every time we fire, I'm really looking forward to being able to focus more on the filtering,and filling, not firing will let us pay more attention to everything else, thanks again guys

The best part about oil is shutdown. Last night during our final boil, we had a drawoff literally 30 seconds before shutdown. Never would have got there with wood because we would have been in cool down mode. You can run the rigs full bore until you’re nearly out of sap. No 1+ hour cool down.

[bill m]

It's been my understanding that wood will boil faster then oil but you have to be on top of it nonstop. Maybe the new high efficiency oil fired are better. You have to work a lot harder with wood to keep a good consistent temperature. If I wanted to work harder I would go back to buckets, wood fired and get rid if my RO and filter press.

[Windy Acres]

Now the only thing I'm wondering, with the AUF/AOF that I've added, I'm wondering if I should sell the arch and build a new one?21395

[Windy Acres]

Does anyone have a 2x8 leader reverse fired arch, or any other brand of reverse fired arch that they would be willing to give me some measurements?

[Windy Acres]

So we went with a carlin 201, and a 4 gph 60 degree solid nozzle, I shortened the ramp and added a firewall,
removed all fire bricks and grates, and the aou/auf system. We threw the switch
and at the 9 minute mark both pans are at a full boil! The flue pan actually boils all the way to the back now, it boils so hard we had to cut the air injection way down to keep steam in the hood, shutdown looks super quick also!21564215642156521566

[Mead Maple]

Windy, can you give some update on how your conversion turned out? I’m still looking to get way more out of my oil rig

[DocsMapleSyrup]

Windy, I'd also like to hear how your conversion turned out and what your boil rate is like with the Carlin 201? I'm strongly considering converting my arch and getting different pans or selling my entire evaporator and going with a new oil burning evaporator.

[Windy Acres]

The conversion was as close as it could be I'd say, we were very happy with it, 9 minutes from throwing the switch and full boil from front to back, the consistency was great, I'd say we are still right around 75 gph, we are feeding it with 18%, the stack stays right at 715, if you would like to see videos of it, check them out on our Facebook page Windy Acres Maple Syrup LLC
