Tom and Stovers,<br>
<br>
Thanks for that reference and abstract.<br>
<br>
I am not going to pay about US$40 to read it, but when someone does,
please send comments to the Stoves Listserv. I am particularly
interested in the

"Char mode". Interesting. Burning char in a TLUD is not good
practice for cooking, but maybe the laboratory scientists want to
learn about something that is sub-optimal for cooking and shortens
the life of the stove. This is all too common in the "peer
reviewed" publications: Out of touch with the real-world
applications of micro-gasifiers.<br>
<br>
But maybe it is not a TLUD???? "fixed bed micro-gasifier stove"
might be something else? Or do the researchers choose to ignore
body of literature with TLUD mentioned?? The list of references
(seen at the provided link) certainly avoid any document with TLUD
in its name, but did include the first edition (2011) of Christa
Roth's major book.<br>

paper deals with the effect of different biomass fuels used
in a fixed bed advanced micro-gasifier cook stove’s
combustion process. Combustion of different biomass fuels
like coconut shells, Prosopis Juliflora and wood pellets
were investigated in an advanced cook stove for an air
velocity of 3 m/s. The actual testing procedure followed to
evaluate full performance characteristics of the stove was
as per the world standard protocol WBT 4.2.3, and the
results were analyzed in terms of thermal efficiency. The
measured variables like bed temperatures, mass loss and exit
gas composition were used to estimate the combustion
characteristics of each fuel in terms of flame propagation,
fuel burning rate and the combustion quality. The two mode
operations of combustion processes namely flaming and char
mode of the fuels were also studied. The experimental
outcomes provide a clear idea on the impact of the different
fuel properties on flame propagation, burning rate and
indoor air quality. Thus, the flame propagation rates are
0.063, 0.071 and 0.05 mm/s with an average fuel burning rate
of 16, 12 and 10 g/min are achieved. Also the thermal
efficiency of fixed bed micro-gasifier is found to be about
36.7±1 % for coconut shell, 36±1 % for Prosopis Juliflora
and for wood pellets it is about 38.5±1 %.<o:p></o:p></span></p>
