Abstract
Computational Fluid Dynamics (CFD) has been widely used to study Circulation Fluidized Bed (CFB) combustion processes. Analysis of mixed fuel between coal and biomass from PKS (palm kernel shell) in the combustion process that occurs in the boiler at West Kalimantan power plant is carried out by mixing the addition of PKS fuel by 20%, 40%, 60%, and 80%. The simulation uses model set-up data, material properties, and boundary conditions according to PJB (Pembangkitan Jawa Bali) Ketapang's experimental data. Then an analysis was carried out with a fluid flow velocity of 3.2 kg/s and particle sizes of 150 μm, 300 μm, 400 μm, and 500 μm on the erosion rate that occurs on the furnace walls due to sand particles present in the combustion process material at the Steam Power Plant (PLTU). Based on the simulation results of mixing fuel between coal and PKS variations of 20% - 80%, the temperature decreased from 1180℃ – 920.03℃ due to differences in fuel heat. Whereas the erosion rate in the simulation has increased from 0.000189 kg/s – 0.001886 kg/s due to differences in the size of the sand particles and the velocity of the mass flow rate of the particles.
