Richard,
It is the words "feed ... continuously" fuel that is a problem. The
pellet stoves (heaters) are acceptable and successful because the
continuous feeding of fuel is automated. No such luxury with
inexpensive stoves for economically poor people.

quick ignition for small heat loads ...
Makes me wonder about this idea of gettign a small fire ignited
quickly.. Think twigs ; huge surface area to volume ratio, lots of air...
And the Pellet stove aplies the idea ver well.... very little fuel
burning --at any one time but its being fed in continuously and
consistently..
It seems that a tube thru which one fed pencil sized slivers
continuously would be a better move to quick ignition, no matter what
the fuel used.

I think Peter has this well documented. The dim's were from me. The
fuel load is 210 mm dia and the funnel is placed on the centre. The
lesson is that a small diameter will work but slowly. It should be
tapered and it has to have a handle because it gets very hot very rapidly.
>Seems a bit big, but it is essentially a chimney placed onto an amount
(how much) of charcoal and how much tinder.
Normally the charcoal is top-lit so it is just placed on top as an
accelerator. Yes it is big. Smaller just does not deliver the savings
and speed. It is a tool that lasts.
>Probably not directly applicable to "Very small stoves" subject, but
it might be scaleable down in size?
Definitely scalable. It is likely to be the same as the diameter of
the chamber small stoves, not on top. Note that a 5 inch stove is
pretty small if it is Jiko or POCA-like.
>Just a note for comparison. A common charcoal lighter for American
style charcoal grills is a simple cylinder half that height and about
150 mm straight walls, but it has charcoal placed inside (quite
different).
Yes quite different. Different principle and not as effective, and
disturbs the fire, and the heating of the 'charge' does not assist
drying the charcoal below. The cone is much more effective. Try it and
you may introduce it as an accelerator for the TLUD pellet burners.
Incidentally we ran a stove I found in TLUD mode today using kinda
long 8mm pellets (local wood) -- breathed rather too much but apart
from being a biggish flame, ran CO/CO2 at <0.60% for ages (certainly
more than an hour) and?0.30 quite a lot of the time. There is a lot to
be said for the combination. I will try a new TLUD pellet stove tomorrow.

Crispin
