EFM 520 Auger Pitch

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

Thanks for the replies guys! I got a couple good ideas reading your posts. I understand why you built your bin the way you did Chris. While I do enjoy working with the boiler as you do, I also got used to setting the oil boiler t-stat and forgetting about it. I'm going to try to make it as automatic as I can. I'm not interested in loading a 55 gallon drum anymore. Looks like the bins going to be 6' x 7' inside and 9' high. Doug,I know your going to throw it out there that it is a little skimpy not being 8x8 but the real reason is that the sheets of ply were not full sheets. Just didn't feel confortable joining sheets when there is 6-7 tons on top. Tore down all the shelves and put all the crap that was stored on them into their new home yesterday. Today started framing out the bottom part. Kept changing my mind on the design. Just's seems a little hairy with all that weight involved. I like the idea of the little box :) I was going with this dumb idea of a PVC pipe in another PVC pipe with alternating cutouts. Turn the inside pipe to shut off the coal supply. Simple wins out in this case. Sure glad I read Tyler's post before all the crossmembers got cut. Hey Wingnut! When are you going to post pics of those monstrosities that you've bin building. I hear you are quite the wood butcher :lol: :lol: :roll: What are you using 2x4's, 6's, 8's a foot on center? Then putting supports at a 45 degree or coming straight up and nailing the crap out of them? Yeah that plywood is good stuff. I built a couple bins that hang way out the front of the loader that hold 3/4 ton each and they don't budge :)
I think a man does what he can, untill his destiny is revealed. Right now that is trying to sell my EFM plate boilers in 520 and 700 sizes.

I keep about 300 pounds over the auger at any time, just in case, and that allows me forget about it over the weekend in this type of weather. In bitter weather, I'll just add some boards and put 500-600 pounds in that area for the weekend.
That is exactly the reason for the dogbox design to keep a small amount of coal in the auger area so you don't have to shovel that much coal away from the auger area incase you had to work or replace it . The drum inside the bin does the same thing as the doghouse design keeping a small amount of coal in the auger area and keeping you from shoveling
alot of coal away from the auger area.

with out a doghouse or a drum inside the bin you will be shoveling alot of coal away from the auger area when you will
need to work or service the auger As far as making a bin out of Plywood and 2x4 or 2x6 there are plenty of coal bins
that are 10 or 12tons made out of them that are 40 to 50 years old in basements around my area that are still doing the
Job they where made to do hold coal aslong as you build them the correct way you will not have to worry about them falling apart cinder or concrete block are cheap to you can always go that route but why when you have the plywood in hand

If you have a problem with the auger you will need to get into the bin and clear the coal out of the way to get to it
