Abstract

The development of biomass-based renewable energy has received extra momentum due to the petroleum/coal-based energy crisis and global warming. Vacuum suction gasification is capable of creating combustible, power-generating synthesis gas. In this vacuum suction gasification, palm shells biomass and wood pellets performed better than rice husks. The production of synthetic gas was stable. It ran for 6.5 hours straight for the ability of palm shells and wood pellets to maintain sustainable temperatures in the reactor to maintain the gasification reaction. Rice husk was not suitable for this type of gasification. It did not maintain a suitable temperature for the gasification reaction to perform well. Value of heat losses in the lining of the reactor was large, more than 2,000 watts which might be the factor that prevented the rice husk from running well. Water was sprayed onto biomass at the reactor’s input to increase its hydrogen content. Oil palm shells responded well to this treatment. It produced better syngas output sustainably. The wood pellet was not responded well to water spray. It crumbled into small pieces. Rice husk is not responded well either. Syngas produced by the reactor was burned and used to boil water. In this gasification system, palm shells and wood pellets had apparent heat values of 5.62 kW and 5.41 kW, respectively. The efficiency of palm shells and wood pellets results in performances of 29.20 percent and 29.96 percent, respectively.

Abstract

The growing demand for renewable and low-carbon energy has intensified the exploration of biomass residues as alternatives to fossil fuels. Palm shell, an abundant by-product of the palm oil industry, has favorable fixed carbon content and calorific properties for thermochemical conversion through gasification. However, syngas produced from biomass gasification is typically discharged at elevated temperatures, requiring cooling for safe handling and downstream applications. This study experimentally assessed the thermal performance of a water-cooled double-pipe heat exchanger integrated with an open downdraft gasifier using soaked palm shell as feedstock. The evaluation focused on reactor temperature distribution, syngas temperature reduction, heat transfer rate, and cooling effectiveness during continuous operation. The gasification zone, located at a reactor depth of 26–77 cm, maintained a temperature range of 600–900°C during operation. The heat exchanger reduced the syngas temperature from 188.1°C to 35.2°C, corresponding to a heat transfer rate of 1,281.3 W and cooling effectiveness of 97.74% under the tested conditions. These results indicate that the double-pipe heat exchanger provided effective cooling of biomass-derived syngas and can support thermal management in small-scale biomass gasification systems. The results also demonstrate the potential of integrating syngas cooling with downdraft gasification for safer handling and improved downstream compatibility.
