Simulation of concentrated slop combustion in cyclone furnace using Computational Fluid Dynamics (CFD)

This study examined the combustion behavior of concentrated slop in a cyclone furnace, primarily aiming to determine the appropriate amount of air supplied for concentrated slop combustion under the adiabatic process using computational fluid dynamics (CFD) in four different air settings; 100%, 120%, 140% and 160% theoretical air. The results show that 100-120% theoretical air were suitable for concentrated slop combustion because they created a high average temperature and formed cyclone motion in the combustion chamber. Moreover, ash particles swirled against the furnace wall and could be melted into liquid slag, resulting in a decrease of fly ash.
