Custom 275 Gallon Oil Tank Arch

[SSS2017]

So I picked up my oil tank last weekend and my neighbor who is a fabricator will be doing the welding on it for me. I want to do this right the first time so if anybody wants to chime in with their pros and cons please feel free. Take a look at my crappy sketch Also attached are pictures I found of what I want my finished tank to look like.

Some basics:
- 275 gallon tank
- I will get a custom 26"x4.5' flat pan since I boil in batches.
- I'm going to line it with 1" fire blanket and then fire brick as well.

Questions:
- I got the 2" pipe from the guys house I removed it from so I'm thinking of having my neighbor weld that in the cavity that will be sealed off from the back to the front to introduce more air to the fire? Good idea or no? I will also have a cleanout in the front that I can keep open for airflow as well.

- How much fire blanket do you typically use for a tank this size.

Thanks in advance!tank2.jpgtank1.jpgtank.jpg

I have a similar setup and I used a half roll of the blanket but did not insulate the front door istelf.

I would go bigger on the air pipe. Everything else looks good.

Where did you order from and what constitutes a half roll? I've been looking on amazon but I won't really get exact measurements until I cut it open this weekend. Thanks

Thank you. As far as going bigger, I wasn't even going to put anything from back to front but I figured more air can't hurt so I thought I'd use the materials I have on hand. What would you suggest from back to front? Again, initially I was only going to be getting air from leaving the front cleanout door open.

A roll is 2' x 24'

Thanks. I just ordered a roll of 3/4" think. I went with 3/4 just because I'm putting fire brick on top. Having a tough time locating an 8" pipe with a collar that attaches to the drum like the 55 gallon drum kits have for their 6" pipe

Why does everyone stand the oil barrel upright? Lay it flat on it's side and make yourself a 36 by 48 pan. You want that fire just as close to the pan as you can get anyway.

I suggest 8 inch insulated chimney pipe. That had twice or three times the draft that the 6 inch plain stovepipe had.

Make the pan fairly deep. Sap would climb the sides on our six inch pan and jump out running down the side of the barrel making a burnt mess.

I'm no engineer but I was under the assumption that it's stood up so structurally you don't have to do much other than an angle iron frame around the top opening to sure it up. Laying it on it's side with that much weight on it I'm sure you'd have to do some more engineering to get it to not collapse on itself with that much heat and weight from the pan and sap.

Took a while... but my arch is almost ready to go. I helped my neighbor finish it up today, got it home and got the first coat of hi temp paint on.
