Abstract

Acoustic energy output level from regenerator segment of a thermoacoustic engine model is attenuated along it’s loop due to several conditions including minor losses. This article discusses the result of Delta EC simulation of a thermoacoustic engine model acting as simple electric power generator that inserted with two conical segments. The cone segments are capable to lower the energy loss which in turn improve the overall performance of the engine in term of nett heat to acoustic energy conversion efficiency. Combined acoustic energy loss induced by both cones is equivalent to 4.94 watts minor losses. At this condition, regenerator segment amplifies the incoming acoustic energy flow of 57.02 watt up to 93.57 watt, which is equals to 36.55 watts acoustic amplification. It leads to increasing of overall engines heat to acoustic efficiency into 14.05%, which is 1.29% higher than those at the case of without cones. This engine performance improvement addressed to smoother streamline of working fluid flow inside the loop.

Abstract

With the depleting reserves of energy sources and fuel shortages that occur in Indonesia today, it is needed a cheap alternative energy sources and environmentally friendly, one of which is biogas. In this study biogas is generated from horse manure. The fermentation of horse manure can produce biogas with the largest component of the CH4 (49.5%) and CO2 (49.7%). The use of biogas as a fuel is still in the household scale and has not been used optimally. This is due to the biogas still containing high levels of CO2 so that it has low value of heat is produced. This research reduces the CO2 levels by using the Ca(OH)2 or limestone sedimentary, and then react with the CO2 to form CaCO3 and H2O. The variables  studied are the influence of the flow rate of the biogas that CO2 absorbed and CH4. CO2 absorption made by passing the biogas with a variety of flow rates in the Ca(OH)2 at a certain concentration. Gas and Ca(OH)2 contact each other and the chemical reaction occurs. Every 2 minute interval of gas coming out of the absorber is detected by a biogas tester for analysis of absorbed CO2 and CH4 produced. The research results show that the average CO2 can be absorbed at all the variations of biogas flow rate (5 liter/min. 10 liter/min and 15 liter/min) produced CH4 at the biogas flow rate of 10 liter/min is 91%, then at the flow rate of 5 liter/min is 76.2% and at the flow rate of 15 liter/min is 72%.

Abstract

This study aims to determine and test the characteristics of horse feces briquettes without and with NaOH treatment as an alternative fuel. The experiment has been carried out in a laboratory. Biomass has been treated with 8% NaOH for 2 h, and has been compared with untreated biomass briquettes. Characterization of the calorific value and ash content of biomass briquettes and bio charcoal briquettes have been investigated. The results showed that the heat value for briquette samples after being treated increased in the range of 4894.6 cal/g – 5855.16 cal/g, while the ash content decreased in the range of 39% to 49.44%; this is caused by a decrease in non-lignocellulosic of horse feces content. It can be concluded that the horse feces biomass briquette with NaOH treatment can be an alternative fuel to replace the skin and leaf briquettes.
