Ash Auger Idea

Ash Auger Idea

PostBy: Kungur On: Tue Dec 27, 2011 10:02 pm

Now that my KA-2 and DHW set-up is working quite nicely. I have begun to consider the next improvement.
I have been thinking about some type of Ash Removal system using an auger. I was thinking about using plant bulb augers, maybe welding a few together. Running them at a angle up and out of the side of the boiler to a ash can.
Thoughts?

That is the best idea I ever heard. Your a genius.

Ash is the only part of coal burning that is less than perfect. Having an easy way to get rid of the ash would benefit all mankind. :)

Call Arnie at A&B Van Wert. He has ash removal setup on his own boiler.

It is a great idea, but I believe the genius was Fred Kalmbach, founder of EFM. AFAIK he invented the coal stoker w/automatic ash removal in the 1920's. I have an example of his handiwork in my basement:

I think there are various threads here that address ways to accomplish automatic ash removal.

Mike, After looking at your pic I have a question. Are there 2 augers,oone at 90 degrees to the other?

This one has an auger that brings the ash straight out from the combustion chamber, and deposits it in the base of a bucket elevator that operates at a 90 deg angle from the auger. I have also seen other manufacturers (Motor Stokor comes to mind) that used the same basic set-up but with a second auger instead of the bucket elevator. I think EFM also had a paddle system for the elevator on some models (in fact, I think I have one in my garage that would go on a UFR). Maybe people who have seen other set-ups will chime in, too.

The general idea of using one auger at an angle instead of a horizontal auger and an elevator generally sounds plausible, but I would have one reservation. The burn pot on the EFM's with ash removal rotated, and had "wings" on the side that swept the ash into the horizontal auger. Any clinkers, etc. would tend to get broken up by the wings and forced into the auger. A "new" system that doesn't do that might tend to clog up, at least if it uses red ash coal.

The ash from my KA-6 tends to cake. Comes off the plates in big pieces in hot and heavy running conditions. The auger would have to manage your biggest chuncks/klinkers. The auger would have be strong enough to grind or break up these larger chuncks. It needs to be durable to withstand such abrasive action. Brock Grain Systems have flexible 2-3-4 inch auger systems to move grain. You can get plastic outside tubing or METAL. The parts are pricey. Takes an electric motor at your final dumping point to run it. Not sure if coal gas could escape through it to human quarters. But if the auger exited to the out of doors.....

Some else on here was moving the ashes outside using a leaf blower on top of and air tight box to suck the ashes up and out. I believe he removed them from the stove/boiler then put a flexible tubing into the bucket to suck them out thus taking away the step of hauling the bucket out through the house/basement.

Automatic fill... automatic ash removal....never ending/uninterupted power source. :up: :drunk:
