Abstract

Today's technological growth is very rapid, companies continue to develop in technological innovation in their products. At the same time, it is necessary to increase adequate energy such as electric power, chemical power, and renewable alternative fuels to replace diesel oil, namely Biodiesel. As of January 2020, the government has implemented a fuel mixture for the transportation sector containing 30% biodiesel in diesel oil. There are many types of biodiesel processing technologies, including non-catalyst technology. This technology only requires raw materials in the form of oil and methanol, without using a catalyst. The use of methanol in the form of superheated vapor in a non-catalyzed response requires equipment that can replace liquid methanol into superheated methanol vapor. The conversion of methanol to superheated methanol in this research was carried out using a methanol preheater based on a design from previous research using the ChemCAD application. namely heating methanol indirectly through a heating fluid in the form of Mobiltherm 605 thermal oil. With mobiltherm hot at a temperature of 50ºC, the pump performance results are obtained with Capacity (Q) 0.0003 m^3/s, Head (H) 0.019 m, Power hydraulic (N_h) 119 watts, and efficiency (η) 95.2%. The greater the value of the density of the fluid, the greater the power used. In the case of Mobiltherm, which has a different fluid viscosity from water, the hydraulic power and efficiency obtained are also high. The mobiltherm 605 heat transfer rate is 35% through the double pipe annulus and the methanol temperature rate through the double pipe inner pipe

Abstract

Bioethanol is a clean fuel, renewable energy source that can be used in place of fossil fuels. Bioethanol has similar characteristics to gasoline fuel, making it an excellent alternative fuel for SI engines, contributing to the reduction of air pollution, the increased use of biofuels, and the removal of fossil fuel consumption. Analysis of the SI engine performance using gasoline fuel with an octane rating of 90 and gasoline-bioethanol blends containing up to 20% bioethanol concentration, each fuel blended at 5% by volume fraction. The purpose of this study is to present the experimental results for a spark ignition (SI) engine with a single injector that operates by using a gasoline-bioethanol blend as fuel. Analysis of the SI engine performance by using gasoline fuel with an octane rating of 90 and gasoline-bioethanol blends containing up to 20% bioethanol concentration. Each fuel was blended with bioethanol at an interval of 5% by volume fraction. The test was conducted on an SI engine with a capacity of 1500 cc, four cylinders, and a single injector was used to distribute fuel to each cylinder through the intake manifold. The shaft of the engine is connected to a 75 kW of eddy current dynamometer shaft to measure the engine torque. The engine load is controlled using an interface computer system. Load on an engine is done by increasing braking on the dynamometer, and real-time signals from the sensors are recorded. Each fuel sample is operated at full load or wide-open throttle (WOT) at speeds ranging from 1000 to 5500 revolutions per minute (rpm). The experiments show that adding bioethanol to gasoline fuel can have a significant effect on the single injector SI engine performance. When the bioethanol concentration of 10% (E10) by volume is used, it is possible to maintain engine power with lower fuel consumption or lower the energy supply to the engine cylinder, thereby increasing the thermal efficiency of the single-injector SI engine by 6.33% compared to gasoline fuel.

Abstract

Coal quality assessment is crucial for determining its suitability as a fuel for power generation and industrial applications. Such evaluation generally involves proximate and ultimate analyses. The proximate analysis provides information on moisture, volatile matter, fixed carbon, and ash content, whereas the ultimate analysis identifies elemental composition such as carbon, hydrogen, oxygen, nitrogen, and sulfur. Geological factors, including age, temperature, and pressure during formation, strongly influence coal quality. This study aims to evaluate the effect of particle size on coal quality using grain sizes of 40 and 60 mesh, analyzed according to ASTM standard procedures. The results indicate that coal with a grain size of 40 mesh contains, on average, 22.22% moisture, 5.83% ash, 37.54% volatile matter, and 34.15% fixed carbon. In contrast, coal with a grain size of 60 mesh exhibits 20.45% moisture, 6.80% ash, 42.77% volatile matter, and 29.99% fixed carbon. These findings highlight the significant influence of particle size on the proximate characteristics of coal, which can affect its combustion behavior and potential applications in power plants and other industries
