Abstract :
Because of possible future energy crises, it is increasingly desirable to
search for alternative and renewable energy resources. This paper presents
a detailed experimental study of direct combustion of a diesel and olivecake
(~C) slurry in a vertical, cylindrical, water-cooled combustor, An
air-atomized nozzle was used in this study and experiments were undertaken
to characterize the atomizerʹs performance. Axial and radial flame
temperature profiles, the heat transfer distribution for the water jacket,
flame stability and combustion efficiency were obtained over wide ranges of
airfuel ratios, and at different percentages of DC in the diesel fuel.
The rate of heat transfer to the water jacket and the combustion
efficiency were improved as the percentage of DC in the diesel fuel was
increased to 7 wt%. Also, as the percentage of DC in the diesel fuel
increased, the stability loop became narrower. Stable flames were observed
for up to 20 wt% of DC. Based on these results and on the availability of
the DC, it may be concluded that the potential of DC as a source of energy
is significant. Copyright
