Abstract
Fluidized bed gasifier type is highly efficient gasifier because the overall thermal efficiency typically ranges from 75% to more than 90%, depending on ash content and fuel moisture. The computational study in this research aimed to analyze the temperature distribution, syngas quality and efficiency of self-bed feedstock in bubbling fluidized bed gasifier for lab scale modelling that supports further research. By using Equivalent Ratio (ER) of 0.24-0.45, the CFD simulation results obtained was syngas composition used as parameters. From these parameters, the highest LHV value was 7.77 MJ/Nm3, the highest yield gas was 1.40 m3/kg, and the optimum CGE was 70.18%. This research aimed to approach the urban gasifier model below 5 kW without silica bed for practical using.
