What size oil nozzle for a 3 X 12

[wiam]

I have pans ordered and built an arch. Looking for ideas on what size nozzle to feed it?

There is a couple of formulas that I saw on Atkinson maple site.

Width of evaporator x length/5 So 3x12=36 36/5=7.2 or if you know the gallons of water evaporated an hour divide that number by 13 it says either way down size by 20% for test fire and then increase upwards if necessary.

Going by that mine would use 9.8 which would be a 4 and a 5 but when I got it it had 2) 6gph. I actually talked to Thad and he was very helpful he built his and he tried all sorts of nozzles he told me to get 6 gph 80 degree hollow nozzles. He said the 80 degree will heat the corners better. His evaporator is 6x16 I think with 2 guns I'm sure he would give you some input if you asked him.

Thanks for the link treefinder.

Thanks for the formulas Jared. I have been talking to Thad. My arch is a copy of Thad's and his cousin Brian. Just finished building arch. Pans coming soon I hope. Quite a bit smaller than Thad's so he was not sure on nozzle size. This is just for this year I think. My plan is to burn chips.

Well I think Thad got the 80 degree part right for sure. Mine is 3.5x14 so I would think you want 8-10 gph. I am not in oil country and I had one hell of a time getting the nozzles just got them December I ordered 2 5gph and 2 6 gph I am hoping to test boil all 3 combinations 2) 5 2) 6 and 1) 5 with 1) 6 before the season interested if I can save a little fuel (not that 1-2 gallons means a whole lot) and still get the same boil. My stack temp runs about 750-800 the correct setting for the barometric damper is important as well.
