Of course - we know I don't fuel with coal -- so my material is lighter.
That written ---- I recently began to blend pellets made from waste paper,into the fuel. Just like the big coal plants or Wisconsin
Ya Right -- there were cheep - that's the reason.
With that mix came fuel bridging above the appliance hopper fall out --
So I bought a 1rpm motor from Grainger -- attached it as close to the bottom of the hopper as would fit - made a 8 inch shaft to fit on - attached two 10x24 2-1/2 inch long machine screws 2 and 3 inches from the near end and two 1 inch further up
WaLA -- no more drama.
In fact I just did this last night -- sorry no pics -- I was too busy getting it done while I listened to the NG back up boiler firing.
To make sure the primary control of the feed augers wasn't over loaded - I placed a IceCube relay in line that I had laying around -- Nothing better than the feeling of accomplishment after a few crappy life days. Spent about 100.00 bucks - the amount I figured I saved - so far - burning the paper. So its a wash for now- but now I can confidently go get more paper.
