“…The flow rate of the gasifying agent was controlled using an airflow meter while liquified pressurized gas (LPG) was used to increase the temperature of the bed to a maximum of 400°C. Coals were continuously supplied to increase bed temperature [34][35][36]. A screw-feeder controller was used to measure and control the coal feed rate.…”

Low-Rank Coal (LRC) gasification utilising Fluidised Bed Gasifier (FBG) is more efficient for LRC that has higher reactivity, moisture, tar, volatile, and ash content but lower calorific value compared to other types of coals. This work investigated the application of Computational Fluid Dynamics (CFD) in simulating LRC gasification under different temperatures which is lower (873K), normal (973K) and higher (1073K) temperature atmosphere. Besides that, the effect of LRC type and gasifying agents on the producer gas CO+H2 composition, Lower Heating Value (LHV) and Cold Gas Efficiency (CGE) were also studied using High-rank Coal (HRC) as comparison. The results obtained showed that LRC gasification using oxygen increased LHV and CGE. Lower temperature gasification using oxygen at 873 increased CO+H2, LHV and CGE for LRC compared to higher temperatures at 973K and 1073K. This prediction suggests that LRC gasification using oxygen at lower temperature increases the LRC gasification efficiency.

“…The analysis of the hydrocarbons and permanent gas analysis was conducted using two detectors which are the flame ionization detector (FID) and the thermal conductivity detector (TCD). The results used in this experiment were all obtained from the gasifier freeboard [34][35][36].…”
