I'm sure someone has already thought about this, but I have not seen much, if any real discussion about it. The idea is to have a chamber, secondary to the combustion chamber ( it could very well serve as a masonry bell), where the hot exhaust gasses are encouraged to flow in a vortex pattern causing the vast majority of the ash to fall out on the floor of the center of the chamber. I think it would be pretty easy to accomplish, say, in a rectangular bell, having the flue gas enter the chamber from the burn chamber side at a low corner, and then flow out the opposing wall from the opposite, top, corner. This should invoke a circular flow and encourage the heavy stuff to fall out into the center where it can be easily reached by a cleanout. Seems to me that such an arrangement could very well capture a large percentage of the ash and make the extremities of the system much less likely to become clogged.
Anyone tried this?
Thoughts?
11/28/2020 Edit. Here is a link to an animation of a Cyclone Separator that is right along the lines of what I was thinking about. In this application, the top opening of the cyclone would be closest to the exit flue, so the draw would be coming from this point. Dirty air from the burn chamber would be entering from the opening on the side and being spun about the outside wall of the cylinder. The ash could presumably be allowed to simply drop out the bottom and be cleared from a cleanout or perhaps simply falling into a removable collection container.
Is it too much of a stretch to consider dumping the exhaust from the primary burn chamber directly into a insulated cyclone generator such as this as a means of separating particulates while simultaneously providing a secondary burn chamber? Seems as that might offer up a generous dose of the 3 T's.
