SIMULASI PENGARUH UKURAN PARTIKEL DAN EQUIVALENCE RATIO DALAM PROSES GASIFIKASI TANDAN KOSONG KELAPA SAWIT
Abstract: In this study, a
simulation for gasification process of oil palm empty fruit bunches waste
(OPEFB) using a fixed bed gasifier (throat downdraft) by varying the particle
size of OPEFB and equivalence ratio (ER) was investigated. The rate of fuel
consumption was 10 kg/h with air as the oxidizing medium and 1 hour process
time for 1 batch. Simulation was performed with two-dimensional approach (2D)
using Computational Fluid Dynamics (CFD) ANSYS FLUENT 14 software. Simulation
results show that ideal amount of equivalence ratio (ER) for gasification
process of OPEFB pellets with diameter (φ) of 6 mm and 8 mm is 0.1 ≤ ER ≤
0.2. ER variation affects the higher heating value of syngas (HHV), the carbon
efficiency (ηC), gasification efficiency and temperature distribution in the
gasification reactor. Variations in particle size did not have a significant
effect in the gasification process.
