Another coal sucker.....

Im curious.. Is that half inch air bypass that runs down into the coal bin just flush with the other pipe (Im guessing its 1 and a half or 2 inch pvc) OR does it join the bigger pipe at the bottom? Maybe that 1/2 inch bypass tube is clogged? I get the dynamics going on here, I think hahaha.. I agree there is plenty of vacuum since that barrel is collapsing. IM thinking more bypass air would carry the coal up the bigger tube better and may prevent some, if not all of the collapsing. I agree a steel barrel is most likely a better solution.

The half inch bypass goes directly into the bottom of the 2 inch line about one inch from the end of the 2 inch line. It's open. I check it every time I retry after I get the barrel back to its normal shape. :roll: Wiz mentioned adding holes in the 2 inch line to add air. That will help get things going I hope. But I'm still going ahead with the steel barrel when it arrives.

Correction to my earlier estimated wall thickness, I found the cut out i made in the bottom of the barrel for the outlet and was able to measure its thickness at 1/4".

Titleist 1.... So is my blue barrel. I thought this was going to be easy. My steel barrel arrived yesterday. Wiz thought getting my cross pipe to the bin lower would help. Constant redesign. Might attach a flex hose directly to the side of the barrel that can span the distance to the bin, through the bin wall, and reach the farthest corner. One hose with no fittings as low as possible to a steel barrel and maybe this will work.

My bigest problem is the area between the bin and boiler. That is the side of my ash pan door for which I need to get nearly everyday for as long as I have the boiler and don't want to do the limbo under a pipe every time. Look at your design and try to plan ahead. So far I'm only out about $10-15 in fittings & pipe and the same in wood and screws for the frame to hold up the barrel. But the steel barrel just cost me $45 total including shipping to my door. And I bet they don't give 20 feet of flex vaccum hose with a smooth interior away. Never worked with it so I don't even know how tight of a turn/arc it can be bent into. Can"t put too much cash into this or it will approach the cost of an auger set up. The only thing in my favor is the wife wants the dust stopped in hopes of refinishing our basement someday. ;)

Aww that's a bummer!! I get 55 gallon steel barrels at the local hardware store for $16 each.. :( DId you try getting more air into the feed pipe? More air should equal more carrying power?

Lightning,

It broke my heart to have to pay for that barrel with shipping but results stood for themself. Plastic barrel was not going to cut it. I also though about putting a 3/4 conduit to the bottom of the 2 inch coal side suction line. I wonder if that getting blocked with coal. Then I was thinking, what if I hooked up air compressor to the top of the 1/2 inch line and pushed more air to the 2 inch line and then....my eyes spun around..... and I reached for a beer. :beer: And then another :shots:

After further thought, it looks to me like air is acting as a "conveyor belt".. Air coming down the bypass picks up the coal and then carries it up the two inch. SO it makes sense to me that if that bypass is more in contact with the coal - by getting it closer to the end of the two inch AND if it carried more air for the coal to ride up by making the bypass bigger then the conveyor would be more efficient. Forgive me if I'm off base, I haven't tried any of this, this is just my observation 8-)
