Abstract

The burning rate of coconut oil droplets has been investigated experimentally by adding bio-additives of clove oil and eucalyptus oil. Tests were carried out with single droplets suspended on thermocouples at room atmospheric pressure, and room temperature and ignited with a hot wire. The addition of clove oil and eucalyptus oil as bio-additives into coconut oil was 100 ppm and 300 ppm, respectively. The droplet combustion method was chosen to increase the contact area between the air and fuel so that the reactivity of the fuel molecules increases. The results showed that the eugenol compounds contained in clove oil and cineol compounds in eucalyptus oil were both aromatic, and had an unsymmetrical carbon chain geometry structure. Furthermore, this factor can potentially accelerate the occurrence of effective collisions between fuel molecules. Therefore the fuel is combustible, as evidenced by the increased burning rate, where the results show that without bio-additives, the burning rate of crude coconut oil (CCO) is about 0.7 seconds. These results are 0.15 to 0.2 seconds slower than CCO with bio-additive, which is around 0.55 to 0.6 seconds. Moreover, from the observations, it was found that the highest burning rate was achieved in both bio-additives with a concentration of 300 ppm.

Abstract

The effective and efficient use of biomass briquettes is strongly influenced by the type of stove used and the way it is used. This study aims to design a briquette stove by adding an adjuster: the test fuel used honeycomb briquettes and forest fern charcoal. The heat transfer from burning honeycomb briquettes to a pot of water needs to be maintained so that the heat (temperature) remains constant during the combustion process. In the current use of briquettes, the distance between the briquette flame and the pot of water is unstable because the space is getting further away from the pool of cooking water. The combustion distance is getting farther because the bottom of the initial honeycomb briquettes burns out, causing the surface of the briquettes to decrease and move away from the surface of the water pot. Thus the heat given to the pool of water will reduce. The briquette stove needs to be added with an adjuster to overcome this problem. This adjuster serves to raise the honeycomb briquettes if the surface of the briquettes decreases. With the addition of an adjuster, it will be analyzed how much the heat transfer rate and the stability of the burning distance of the honeycomb briquettes will be. In this study, 2 test models will be used: a stove with an adjuster and a stove without an adjuster, using 14 holes in honeycomb briquettes made from forest ferns using starch (tapioca) adhesive. The distance between the surface of the briquettes and the pot of boiled water is 5 cm. The results showed that the briquette stove using an adjuster could maintain the stability of the combustion distance between the surface of the briquette and the pot of water being cooked with an average temperature t = 567.83 0C and conduction heat transfer q = 5285.699 Watt.

Abstract

Biofuel derived from raw vegetable oil is considered a crucial alternative energy source to address the escalating fuel energy crisis due to the growth of industrial activities and the human population. The compounds present in raw coconut oil, including saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, and glycerol, constitute the focus of this research. The combustion of raw coconut oil involves a complex reaction due to the presence of saturated chain bonds, necessitating additional substances to weaken the carbon chains and enhance the combustion rate. This study employs the suspended droplet combustion method to increase the contact between air and fuel, thereby improving the reactivity of fuel molecules. To boost the combustion rate of coconut oil droplets, a bio-additive in the form of clove oil is experimentally added. Research findings reveal that the compound eugenol in clove oil possesses aromatic properties and a non-symmetrical carbon chain geometry. This factor can potentially expedite effective collisions among fuel molecules, consequently improving the ease of fuel combustion. In conclusion, this research provides insights into the potential use of coconut oil as a biofuel, highlighting the role of bio-additives such as clove oil in enhancing combustion rate efficiency. The study contributes to our understanding of strategies that can be applied to optimize the utilization of biofuel derived from raw vegetable oil.

Abstract

The limited availability of diesel oil encourages efforts to find new energy sources as alternative diesel fuels. Biodiesel can be extracted from various agricultural products, for example, coconut oil. As a tropical country, Indonesia is a very effective and potential country as a coconut producer. Vegetable oil has a higher viscosity than diesel oil. Compose bio-oils with various fuels additive is the way to reduce viscosity values, among others, by combining nanocarbon and metal catalysts. This study goals to know the characteristics of burning coconut oil as an alternative fuel with the addition of eucalyptus oil; and how long the combustion process takes from the starting point to the end. The results showed that adding eucalyptus oil to coconut oil can reduce the weakening of the carbon chain and increase the combustion temperature. The combustion efficiency of this coconut oil mixture varies depending on the amount of eucalyptus oil added, resulting in faster fuel combustion and a more powerful explosion. The color of the fire is an essential factor in ensuring that this mixture can be used safely and efficiently.

Abstract

A comparative study on the combustion characteristics of a single droplet fueled by DEX, crude jatropha oil (CJO), and a mixture of CJO with a magnetic liquid catalyst of rhodium trisulfate has been carried out under normal gravity conditions. The high viscosity of crude jatropha oil makes it difficult to burn under normal conditions (room temperature and atmospheric pressure), therefore the addition of a magnetic liquid catalyst rhodium trisulfate is needed to improve the properties of crude jatropha oil. As a catalyst, rhodium trisulfate has the potential to improve combustion performance while improving the physical properties of crude jatropha oil as an alternative fuel for the better. Furthermore, performance tests were also carried out with DEX fuel with a cetane number (CNs) 53. The results showed that compared to DEX, it was seen that the liquid metal catalyst rhodium trisulfate succeeded in making crude jatropha oil more charged so that the combustion process was better. This is evidenced by a significant change in the dimensions of the flame and an increase in the combustion temperature. Moreover, it is also seen that the burning rate increases and the ignition delay become faster.
