Abstract: Renewable energy sources are sustainable energy sources. They are gaining importance, as the fossil fuels are fast depleting and there is pressure for reduced emissions from combustion of fuels. Biomass turns out to be a good candidate as a renewable source of energy. The literature scan shows that the coconut shell powder has not been used in slurries to the extent it deserves in view of its reasonably high calorific value and tendency for low CO emission. newline newline Coconut shell powder is being considered as the biomass component in the biomass slurry fuel. The properties of the slurries have been determined and simple correlations are developed. Based on the properties of the biomass slurry, the appropriate biomass slurry composition is selected for further studies. In this connection, a new guideline- fuel cost index is introduced to assist the selection of the suitable biomass slurry. newline newline Computational fluid dynamics tool-Fluent is used, for the first time, to study the combustion of the biomass slurry in oil-fired furnace. The maximum temperature and the temperature distribution in the furnace are predicted. The emissions from the outlet of the furnace are also predicted. It has been observed that the maximum temperature in the furnace reduces with the increase in the percentage of coconut shell powder. It is also observed from the CFD analysis that the CO emission reduces with the increase in coconut shell powder in the slurry (up to 30%). The composition of the slurry investigated is varied from pure Light Diesel Oil to a maximum coconut shell powder percentage of 30%, along with 10% of water. newline newline
