Abstract

A boiler Is a steam-producing closed vessel that can convert chemical energy from fuel into pressurized steam. The steam is used as an electrical power source and for the processing of oil palm fruit. Researchers use direct observation methods to identify specimens and parameters. To analyze the efficiency of thermal boilers and Specific Fuel Consumption (SFC) using 100% fiber fuel and a combination of 70% fiber and 30% shell. From the results of this study, it is stated that using 100% fiber fuel produces 68.1% thermal boiler efficiency, and an SFC value of 13.37 kg/kWh is obtained. The combined fuel use of 70% fiber and 30% shell results in 74.2% thermal boiler efficiency and an SFC value of 10,98 kg/kWh is obtained. So that the efficiency of thermal boilers has increased by 6.1% and the SFC value has decreased by 2.39 kg/kWh.  The improvement in boiler performance and low SFC value is due to the high calorific value of fiber and shell combination fuel which is 12799.343 kJ/kg and low fuel consumption of 5492.53 kg/hour.

Abstract

Rack grate is a component composed of rack clip and rack bone arrangement that serves as a dropping cross-section media of coal and as a media of coal burned in the boiler.  As part of the main component, the rack grate can be regarded as one of the components that ensure the success of combustion in the boiler. Failure to this component will certainly interfere with the implementation of boiler operations. In addition to require the boiler to be shut down while repaired, in addition to requiring the boiler to be extinguished during repairs, the inoperability of the boiler makes the steam production process at the PLTU impossible and ultimately the electricity generation process cannot be carried out as usual. Damage to the rack grate component has a type of plastic deformation with variable loads and fluctuating heat, which means that the thermal stress in the system has reached the yield stress point. To find out the root cause of this component damage quickly and accurately, an analysis of the results of the implementation of engineering software in this case Ansys Workbench, and a comparison of actual operating data, and data design is the best choice. Lastly, by evaluating the optimum values of temperature, equivalent stress and strain, total deformation, input process parameters value can be controlled to the desired values, resulting in less stress concentration occurs, so that the damage to the workpiece can be reduced or even eliminated.

Abstract

This research aims to determine the effect of varying reaction times (60, 70, 80, 90, and 100 minutes) at a temperature of 65℃ and a rotation speed of 1050 rpm on the density and iodine number of biodiesel. The raw material used for biodiesel production is waste cooking oil. This study employs esterification and transesterification processes by reacting catalysts with methanol mixed with waste cooking oil. The catalyst concentration variations used in this study are methanol at a ratio of 1:2 and 0.5% NaOH of the total waste cooking oil. The transesterification product is then settled for approximately 10 minutes. The resulting biodiesel and glycerol are separated, after which the biodiesel is washed with distilled water at 50℃ and evaporated at 90-100℃. The density test results for the catalyst concentration of methanol at 1:2 and 0.5% NaOH showed values of 858.5 kg/m³ for reaction times of 60, 70, and 80 minutes, 858.7 kg/m³ for 90 minutes, and 858.4 kg/m³ for 100 minutes. The iodine number test results showed values of 87.2 for 60 minutes, 88.3 for 70 minutes, 90.2 for 80 minutes, 92.3 for 90 minutes, and 82.3 for 100 minutes. The research findings indicate that the obtained density and iodine number meet biodiesel quality standards and are suitable for use according to ESDM regulations.

Abstract

Biodiesel is a potential alternative to replace diesel because its raw materials are renewable and environmentally friendly. One of the raw materials used is waste cooking oil. The high content of free fatty acids in waste cooking oil requires pretreatment in the form of esterification before the transesterification process. This study aims to determine the effect of reaction time variations (60, 70, 80, 90, and 100 minutes) at a temperature of 60°C and a stirring speed of 1050 rpm on biodiesel's flash point and viscosity. The biodiesel production process was carried out in two stages: esterification and transesterification. The catalyst concentration was methanol at a 1:2 ratio and NaOH at 0.5% of the waste cooking oil. After transesterification, the mixture was allowed to settle for 20 minutes. The produced biodiesel was washed with distilled water at 50°C and evaporated at 90-100°C. The flash point test results for the reaction time variations showed the following values: 60 minutes (108.5), 70 minutes (182.5), 80 minutes (182.5), 90 minutes (148.5), and 100 minutes (184.5). The results indicated that the cetane number obtained did not meet the biodiesel quality standards and was not yet suitable for use according to the Ministry of Energy and Mineral Resources (ESDM) regulations.

Abstract

Biodiesel is a potential alternative to replace diesel due to its renewable and environmentally friendly raw materials. Used cooking oil can be utilized as a feedstock for biodiesel; however, the high free fatty acid content requires pretreatment with esterification before transesterification. This study aims to determine the effect of reaction time variation (60, 70, 80, 90, 100 minutes) on the cetane number of biodiesel produced at 60°C and a speed of 1050 rpm. The esterification and transesterification processes use 0.5% NaOH catalyst and methanol in a 1:2 ratio, mixed with used cooking oil. After transesterification, the mixture is settled for 20 minutes, then the biodiesel is separated and washed with distilled water at 50°C and evaporated at 90-100°C. The cetane number test results are as follows: 60 minutes (44.54), 70 minutes (44.54), 80 minutes (44.54), 90 minutes (44.47), and 100 minutes (44.60). This study shows that the cetane number of the produced biodiesel does not meet the biodiesel quality standards and is not yet suitable for use by the Ministry of Energy and Mineral Resources (ESDM).
