[Stoves] TLUD Syngas Flame and the Red-Hot Chimney in a Kerosene Heater.

[Julien Winter]

Hello stovers;

I took my  Kero-Sun Radiant 10 apart.  There are some photographs of the
inner and outer chimneys in the attached pdf.

The inner chimney as baffles at the bottom and is enclosed, with
perforations at the top.

For sport, I put the inner chimney, and then the inner chimney nested in
the outer chimney on top of a 7.5 cm diameter natural draft TLUD.  As we
might expect, it created resistance to exhaust gas flow, that reduced the
secondary uptake, and caused the TLUD to emit a small amount of visible
smoke.   I did this in daylight, so I don't know if any of the chimney
assembly became red hot.

In order to investigate this properly, I would have to destroy the chimneys
by breaking off the baffles, and expanding the diameter of the perforations
in the chimney walls --- and I am not prepared to do that.  What is needed
is to find a kerosene heater wreckers yard to scavenge bits.

Thus, it is still an open question (for me anyway) if something like the
chimneys in kerosene heaters, or a type of catalytic converter, can reduce
soot production from natural draft TLUDs.

Cheers,
Julien
