Mentioned in my initial roll call post that I was aiming to get going on a reverse flow build project. Finally managed to secure a 100 gallon/400 litre (approx) compressor tank and so will be getting the build work started ASAP!
Full disclosure; I don't have the welding/metal work skills to actually build it myself and so figured rather than be foolish, best to work with a local fabricator to get this done! I'm doing the design/spec and than will pay a pro for the hard work!
I'm still working on my design so at this point, I would be grateful for people's input and guidance/advice.
This is the tank:
1/4" thick all over. Lengthways, it measures about 67" - 60" weld to weld - and then around an additional 3.5" at each of the capped ends.
Diameter is approx. 20 inches. (I'm noting most measures as approx. as I have had the numbers given to me by the supplier/fabricators but I want to measure myself when I visit the yard tomorrow, before I start talking absolutes.)
For now, I will use the measures I have in order to be able to check on my workings (if I measue tomorrow and there is any difference, I can amend there and then.
As it stands, based on 67" length and 20" diameter - adjusting for loss of 1/4" due to thickness shell:
FB/CC opening: 78.3
Going for a larger FB than required by the calc- 10,648 vs. 6457.9. Will be 22x22x22in, with an additional 4in below the bottom (6in below the grate) for ash dump. Will be 1/4in steel all round and will likely insulate.
Air inlets: 21in total (slightly over the 19.6 calculation but makes it easer to measure) Will be split as follows: 4x3in inlets at/just below grate level, 3x3in inlets opposite the FB/CC opening.
RF plate will be 18" length 60.375 inches length by 18in" width.
Will be going for two doors; 26in length, cut at half way and at the 80° degree mark. Will leave 2 inches at either end from the weld line, with a 2in strip in the middle.
That's where I'm up to so far, essentially what I need to get the work underway- doors cut, steel for FB ordered, FB assembled and fitted, RF plate ordered and fitted.
I would be grateful for any number/calculation checking if anybody's up for it. Off to sit down with my fabricator/welding guy tomorrow and will take some final measures before finalising plans. Once I get underway, I plan to be checking in on the build pretty frequently so will try to take and post pics/updates as it comes along.
And before I forget, shout to Boomhower; the final product I am shooting for was very much influenced by his own 100 Gallon build. Also DaveOMak, Ribwizzard, LenDecaturAL, Gary S and anybody else who gave great advice/answers to other peoples questions that I just stole information from! :-)
