“…The uniqueness of this dryer relied mainly on the shape of the structure as depicted in Figure 1, the design of the heat exchanger as described in detail above, and free from electricity dependence which makes it possible for application in remote areas. Furthermore, the performance of the heat collector may be improved by adopting a solar tracking system [35] while the efficiency of the furnace can be increased since it was found that the gasifier efficiency for biomass was between 50-80% [36]. Finally, the operation of the dryer may be optimized seeing that a device for future solar irradiance prediction may soon be available [37].…”

The solar-biomass hybrid dryer had been developed, and recently its design was improved. The dryer was basically UV12% plastic house, equipped with a drying chamber with the trays inside, two heat collector, a furnace embedded in a heat exchanger and a chimney. The objective of this study was to investigate the performance of the dryer after the design was improved by testing it for fish drying with different modes of energy supply i.e: solar energy (SE), biomass energy (BE), solar energy followed by biomass energy (SEBE), and simultaneous solar energy and biomass energy (SEBES). Coconut shell was used as the biomass energy source, and "Bleberan"fish (Pepetak Leiognatus spp.) was employed as the experimental commodity. SE mode generated the average drying air temperature 10.6 o C higher than that of ambient air and the average drying air relative humidity 21.9% lower than that of ambient air, and completed the drying process in 16.6 hours compared to 23.3 hours needed to finish the drying process for the sun drying. Operating with 3 kg fuel first supply and 1.5 kg fuel subsequent supplies per 20 minutes, BE mode produced the average drying air temperature 28.2 o C higher than that of ambient air and the average drying air relative humidity 44.7% lower than that of ambient air, and the drying process was completed in 8.6 hours with the fuel consumption of 0.375 kg biomass per kg wet fish. In SEBE mode with the same fuel supplies as BE mode, the average drying air temperature was 27,7 o C higher than that of ambient air, and the average drying air relative humidity was 45% lower than that of ambient air, and the drying process was completed in 13.4 hours with the fuel consumption of 0.19 kg biomass per kg wet fish. For SEBES mode with 3 kg fuel first supply and 1 kg fuel subsequent supplies, the average drying air temperature was 25.6 o C higher than that of ambient air, the average drying air relative humidity was 43.9% lower than that of ambient air, and the dryer finished the drying process in 9.1 hours and consumed 0.29 kg biomass per kg wet fish. The uniqueness of the dryer was manifested by its shape, the heat exchanger and electricity free.

“…Cold gas efficiency (CGE) has a value which was still low at 26.31% compared to gasification which have efficiency 50-70% [18]. It is caused by two factors, namely the calorific value fuel gas produced was still low and the remainder of the conversion of coal powder were still mostly in the form of charcoal.…”

Fixed bed gasification of coal generate some by-products, such as tar and coal powder. Coal powder obtained because the coal feed for fixed bed gasification reactor must have a size above 20 mm. Meanwhile, tar is a high molecular weight hydrocarbon compounds that will condense at low temperatures, which cause clogging and blocking of pipes. In this study, experiment on combustible gas generation from co-gasification of tar and coal powder was conducted in an auto-thermal reactor to determine the temperature of the process, combustible gas composition, and efficiency of the process. From calculation and experiments about oxidizing reactor operation, 20 kg/hr of tar was more promising to operate and can reach the optimal temperature which was 1900ºC. The energy from oxidizing reactor used for the reduction reaction of tar and pyrolysis of coal powder and produce combustible yield gas. The coal powder that can be conversion was about 14.4 kg/hr and produce approximately 84.52 kg/hr combustible gas. The calorific value of combustible yield gas amounted to 783.62 Cal/g. Combustible yield gas has advantages levels of hydrogen gas (H 2) as high as 19.2%, which is already exceeding the levels of hydrogen gas from coal gasification is only <10%. Cold gas efficiency (CGE) has a value which was still low at 26.31%. It is caused by two factors, namely the calorific value fuel gas produced was still low and the remainder of the conversion of coal powder were still mostly in the form of charcoal.

“…Chaves et al [13] conducted a study on spark ignition engines using gasoline (single fuel) and producer gas (single fuel) from wood waste gasification, and test results show that the producer gas reduced nominal power by 50%. Efendi et al [14] tested producer gas, produced from coal gasification, as a single fuel in a spark ignition engine. The results of the test showed a decrease in electric power by 46% when using the producer gas as fuel.…”

This study proposed a dual fuel operation of a mix of gasoline and producer gas from coal gasification on the spark ignition engine. The experiment was carried out on a constant load with variations in speed for single fuel operation of gasoline and dual fuel operation of a mix of gasoline and producer gas to see the influence on speed, torque, power, and braking (effective pressure). The power produced was compared to power produced by the single fuel of producer gas that has been reported in the literature. The result shows an increase of speed would increase torque, power, and braking (effective pressure) for single fuel operation of gasoline and dual fuel operation of a mix of gasoline and producer gas. The power operation of dual fuel of a mix of and gasoline and producer gas will decrease by about 10.9% compared to operation of single fuel of gasoline, and the power operation of the single fuel of producer gas will decrease by about 20% compared to the operation of the single fuel of gasoline. The maximum shaft power produced by dual fuel operation is 1.49 kW at a load of 5 kg and a speed of about 3,500 rpm.
