摘要

The sugarcane bagasse fuel is an energetic deposit opportunity for thermal and electricity generation in sugar society.Combustion behaviors,essential for effective operation of these devices are a necessity.A 3D numerical model has been developed in the commercial software Ansys Fluent.According to the fuel density and particle variable,this model took into account both suspension and grate model combustion.The realizable k-ε turbulent model with the P-1 model shows its advantage of describing such king problems and has been applied on the numerical model.The contour of the temperature,spices and the particle trajectory provided a clear understanding of bagasse fuel combustion in the furnace as well,bagasse particle goes through from initial heating to char combustion and its conversion to ash.The results obtained were in accordance with those of the literature.These results could be used to analyze this inexpensive combustion process for looking for the effect of design parameter change on the furnace performance.
