[Stoves] partial fan compensation by static-mixers?

[Boll, Martin Dr.]

and to all now discussing the possible advantage of the Swosthee-stove.

 

Subject of the Aprovechio-meeting will be fan-use in stoves. I think, there
is a lot of interest to get some "natural-draft-surrogate" to replace or
partly replace electrically fans.

As I nudged the interest for the Swosthee-stove (Vortex helping for
gas-mixing/better-draft),

 

I want to re-introduce the idea for using static-mixers. (Now not in
stove-pipes for equal heat dispersion within the cross section, to get
better radiant heat use at the tube-wall, my first proposal, but:) 

 

There are ceramic static-mixers, which I guess, could be suited to be used
in burning-chambers of stoves. Does it sheet-metal do as well?

Using static mixers, good gas-mixture would be possible with less draft,
possibly with natural draft, (when not enough draft: additional augmented by
other "tricks"?).

 

As Kevin Chrisholm answered to my proposal to use static-mixers, some months
ago, he was enjoyed, that static-mixers could catch tar in pipes (-his
idea-)

And his meaning was: static mixers could be constructed relatively simple.

There was no further discussion in the stoves-list, neither about the
geometry of static-mixers nor about the construction/fabrication.

 

Possibly it would be interesting to have some static-mixers by hand, to
"hang" them into any stove burning-chamber (-let them warm up-) and have a
look, if the effect they make, is interesting and promising to make
seriously experiments. 

Even the effect of slowing down the draft must be considered which is
sometimes desired but mostly not wanted.

Would that be an effect, less important than better mixing of the burning
gasses?

 

 

Can we possibly reach a "comfortable stirring" the burning gasses?

-Though we know, an electrical fan is most comfortable -
