Abstract

Several studies have proven the efficiency of gasification as a thermal process in terms of material decomposition and chemical energy. Synthetic gas (syngas) is a gasification product that can be used as an energy source. However, it needs to undergo treatment to remove the tar content, which could cause several issues in the combustion system. Tar removal can be conducted through biomass filters. In this study, three types of filters were investigated: biochar, rice straw, and rice husk filters. Three thicknesses of the porous media (30, 40, and 50 cm) were investigated. The results revealed that porous media thickness significantly affects tar removal efficiency, as the efficiency was found to increase with the thickness. Biochar was proven to be the best filter media among the three types, with a tar removal efficiency of 59.45% at a thickness of 50 cm.

Abstract

Gasification is considered a promising option for harnessing energy potential from agricultural waste, such as rice husks. This paper presents a 10-kW rice husk fixed bed gasifier system. This system is an improved version of a prototype previously developed by our research group. Some of the optimized features added to the gasifier include the use of a circular air intake, an improved gas cleaning system, and electric motors that are regulated by a programmable logic controller. Keeping the gasifier system’s operation stable is critical for producing high-quality synthetic gas (syngas). Therefore, performance evaluation of the presented gasifier system was conducted, and the resulting syngas outputs were analyzed. The evaluation also included an investigation into the performance of the motors, particularly those used for feeding and char removal, which are critical components of the system. The results showed that the improved gasifier system was stable with a proper feedstock. A discussion of the parameters affecting the composition of the synthetic gas is also presented.
