Abstract

Meningkatkan distribusi temperatur pada meso combustor merupakan cara yang efektif dalam meningkatkan efisiensi sistem pembangkit daya micro TPV (thermophotovoltaic). Diameter combustor sangat mempengaruhi distribusi temperatur pada combustor. Tujuan dari penelitian dalam karya tulis ilmiah ini adalah untuk mengamati pengaruh variasi diameter combustor terhadap temperatur dengan mengukur temperatur dinding (Tw) dan ruang bakar (Ti) pada tiga variasi diameter outlet (Do) combustor berukuran 5 mm, 5,5 mm dan 6 mm dengan diameter inlet (Di) yang konstan sebesar 4,5 mm. Hasil penelitian menunjukan bahwa diameter meso combustor sangat mempengaruhi suhu pada dinding dan ruang bakar. Suhu pada dinding combustor (Tw) dipengaruhi oleh besaran surface to volume ratio karena variasi diameter pada combustor, dimana semakin besar nilai rasio (Do combustor kecil) akan menghasilkan suhu dinding yang lebih tinggi, namun dengan heat losses yang besar. Sedangkan suhu pada ruang bakar combustor (Ti) dipengaruhi oleh besarnya vortex yang terbentuk di area sudden expansion. Sudden expansion berukuran besar (Do combustor besar) akan membentuk vortex yang besar sehingga meningkatkan suhu ruang bakar, namun membuat nyala api semakin tidak stabil karena massa berlebih yang dibawa oleh vortex ke dalam zona reaksi.

Abstract

Diesel engine spray nozzles are crucial to pollutant generation and engine efficiency. Nozzle performance can be enhanced by adjusting the nozzle's internals. A successful demonstration of the nozzle would be one in which the spray's outcome was uniformly dispersed throughout a wide area, with the grains scattered similarly. The purpose of this research was to examine how a diesel-ethanol characteristic under normal atmospheric pressure (spray tip penetration, the velocity of spray, and spray angle) and, in general, to assess the performance of biodiesel fuel on diesel engines, a substantial amount of biodiesel and operational expenses for the engine are necessary. It was an experimental approach to the study. The research involved recording spray fuel at the nozzle. Using a 480 fps high-speed camera, we tested BD20, BD20E5, and BD20E10 fuel at three different ambient pressures (1 bar, 2 bar, and 3 bar). The injection pressure was 15 MPa, and the fuel temperature was 28.2 degrees Celsius. Spray tip penetration and spray velocity decreased and spray angle increased after ethanol was added to the mixture, consistent with the studies' findings. Lowered spray tip penetration, slower spray speeds, and a complete spray angle result from the increased ambient pressure.

Abstract

The use of Liquefied Petroleum Gas (LPG) fuels has increased over time and has triggered the innovation of renewable fuels that do not affect the environment. This renewable fuel is biomass. Biomass is derived from organic materials of plants or animals that can be used as fuel. The conversion of biomass into thermal energy using gasification stoves can increase thermal efficiency up to twice that of conventional biomass combustion. Common stoves that use nowadays is Top-Lit Updraft (TLUD) gasifier that easy to optimize. This type of gasifier has a simple design and can be fuelled with any type of biomass with a water composition of less than 20%. Gasification stoves have so far been developed using various biomass fuels, one of which is bagasse waste. Bagasse is also easy to obtain in Indonesia because it has an abundant number of quantities. In addition to the fuel aspect, the ability of the gasification stove to produce good thermal efficiency depends on the stove design, such as stove type, stove dimensions, and combustion airflow rate. It is tested with the water boiling test method using variations of airflow rate of 2 m/s, 3.5 m/s, 5 m/s, and 6.5 m/s and honeycomb channels addition. As a result, it reached 30% thermal efficiency.

Abstract

Biodiesel predicted to replace diesel fuel in the future that comes from the transesterification process of plant oils, animal fats, or used oils. One of the potential raw materials is nyamplung seeds because they are scattered in Indonesia, easy to cultivate, and bear fruit throughout the year [1]. The purpose of this study was to determine the effect of mixing pure diesel fuel and nyamplung biodiesel with the fuel composition B0, B20, B30, and B100 on the spray tip characteristics penetration, spray angle, and sauter mean diameter.This study focussed on simulation. The simulation method is carried out to predict the distribution and mean diameter of droplet using commercial fluent software. Fuel spray is carried out in free air with an injection pressure of 15 MPa, fuel temperature 28.2 ℃ and free air temperature 30.1 ℃. The spray process was taken at 6.25 ms and then the fuel spray characteristics were measured using the ImageJ application.The results of testing the fuel spray characteristics indicate that the amount of biodiesel content in the fuel is 20-100%. It can increase the length of spray tip penetration about 0.7-4.9%, a decrease in spray angle of 9.2-32.1% and the sauter mean diameter value increased by 20.1-84.6%. It caused by increasing the amount of biodiesel content in the fuel which results in an increase in the value of density, viscosity and surface tension of the fuel.

Abstract

Research on the use of biodiesel as renewable energy must continue to be carried out as an effort to reduce dependence on fossil energy. This research method was carried out using biodiesel from used cooking oil as an additive to fossil diesel fuel (dexlite). The fuel was tested on a diesel engine as a power generator accompanied by variations in power loading (load). The composition of biodiesel as an additive was (10, 20 and 30)% of fossil diesel fuel, while the power load used during testing was 100 to 700 watts. Testing was carried out to determine the performance and fuel consumption of a diesel engine as a power generator. The test results showed that the highest effective power value was in the D0 composition with a value of 278.18 watts with a power load of 700 watts, while the highest torque value was in the D0 fuel composition of 2.23 Nm at a power load of 700 watts. The lowest fuel consumption was in the D70BIO30 fuel composition of 114.25 seconds at a power load of 100 watts.

Abstract

Biomass gasification is a promising renewable energy technology for the production of synthetic gas (syngas), consisting of hydrogen (H₂), carbon monoxide (CO), and methane (CH₄). This technology's primary challenge is tar formation – a heavy hydrocarbon compound that can block equipment, poison catalysts, and deteriorate syngas quality. Therefore, this study aimed to examine different tar reduction methods to support clean energy production through biomass gasification. To achieve this aim, two main approaches were adopted and the first was in-situ, focusing on modifying gasifier design and adjusting operational parameters. The second was ex-situ, which included catalytic reforming, thermal cracking, and plasma technology. The analysis also assessed different catalysts, such as biochar, and dolomite, as well as nickel- and iron-based materials, comparing their efficiency, sustainability, and economic viability. Several key factors influenced tar formation and reduction, namely feedstock type, operating temperature, air ratio, and reactor configuration. The result showed that combining in-situ and ex-situ technologies had substantial potential to significantly reduce tar, improve syngas quality, and optimize system performance. However, some challenges observed were reduced catalyst efficiency, high energy costs, and the need for more sustainable technologies. To improve the performance of gasification systems, this study provided information on catalyst development, operational parameter optimization, and plasma technology integration. Finally, the analysis provided a scientific basis and strategic recommendations to overcome tar problems and encourage the commercial use of biomass gasification towards a clean energy transition.

Abstract

Indonesia's natural resources, such as coffee hulls in Jember Regency, are potential sources of biomass raw materials that can be processed into biomass energy. Gasification is the process of converting solid fuels into combustible gases (CO, CH4, H2) through a heating process with minimal air conditions. This research focuses on the effect of air flow rate on the syngas productivity of coffee husk biomass gasification. It was found that higher air flow rate produces higher syngas content. The highest syngas composition with the highest LHV value was obtained by the 40 SCFH air flow rate variation with an LHV value of 141.7 kJ/mol.

Abstract

The purpose of this study was to determine the effect of eggshell catalyst (CaO) on the combustion characteristics of nyamplung oil biodiesel droplets (Calophyllum inophyllum L) on flame visualization, ignition delay, and temperature. At present, Indonesia still uses fossil fuels, namely diesel. However, over time there are alternative fuels using palm oil raw materials. However, palm oil is also used as a source of food so that it will have an impact on the scarcity of palm oil. In this study, we looked for alternative energy using nyamplung seeds (Calophyllum inophyllum L.) with catalyst weight variations of 1%, 3% and 5%. The tested droplet volume of 1 ml was placed in a type K thermocouple. The results of this study showed that the percentage of catalyst weight increased temperature and shortened ignition delay. The highest temperature and lowest ignition delay were found at a variation of 5% with the highest temperature of 679.5 °C and ignition delay of 3000 ms.
