This webpage describes my experimental adaptation of double spiral flows, incorporated into a chimney. At this first writing, only the spiral inducing features are described.
Callum Coats has generously published several excellent books on Viktor Schauberger's works. (Web search these names for many details and for free download books). Much of Victor's work involves voticies, whirls, flows and natural mimicry applied to engineering. Except that the structural concepts are uniquely revolutionary, which challenges many vested interests. Which is likely why psychopaths repressed him and prevented his best efforts. Thanks to many good people, much of his good work is being brought to public attention.
The first image above is a scant abbreviation of a remarkably well- hand- drawn- vorticular flow pattern. As Viktor visualized elements of his invention for water distribution, in specially modified pipes, (for plumbing). The helical aspects are many, which cross boundaries into many structural applications. This webpage applies the essence of the first drawing, into a chimney flue to whirl the exhaust.
The next image below reveals my construction technique. (Backgrounds are especially blurred to conserve website bandwidth).This stovepipe section (about 1 meter or 3 feet in length), was constructed to be installed in the top of my home dome. It actually also included some insulating features in the final installation, not shown here. The following images focus on the swirl inducing structure and how to easily build it. Over the years, i have innovated many applications for molding cementitious structure.
The mold components include a heavy rubber hose. (Type for expelling auto exhaust from a garage.) Ropes are wound around the hose and food plastic wraps these together. Then these can be loosely fit inside the stove pipe. In addition, holes are marked and later made for the screws. Finally all are positioned as seen to left, in photos above. The screws will anchor the cement which is hand molded into place, as seen in photos below.
The cement is revealed after the wrapped mold components are removed. The stove pipe thus receives a spiral shaped, fixed position, cement vane structure. This vane helps induce spiraling flows. Whirling exhaust contrails can be seen at times, (though would require special efforts to capture in photos or video). Next photo below shows an additional whirl inducer- This inducer, (patch worked and welded together), is fed blower air in case the entire chimney structure happens to have been cooler than outdoor temperatures- Which happens occasionally, before winter starts, when fires are little needed. This chimney is part of a complex masonry heater. I was just upgrading this top portion this Autumn 2013.
The draft in my masonry chimney is overly strong in cold weather, without need for the extra blower-inducer. Rational for blower- inducing drafts is to isolate the blower from the exhaust, which tends to impair blowers or fans. I bought a small surplus blower made for computers. Actually, for my charcoal style of burning, i need special means to dampen or slow the draft.
(If i receive comments on my page, i often am inspired to add more text and photos. So please be encouraged to ask questions or comment. Unfortunately, my email is sometimes intercepted, so keep trying. It's just a growing feature of our times.)
