This is just the abstract but how do these results compare with tests of
similar stoves? How would other, or additional, tests that have been
mentioned in the last few months change the results or use of the data?

Abstract


This 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 %.
