Characterization of bioetanol gel and applications on bioethanol gel stove

Bioethanol gel has several advantages over solid fuel briquettes and paraffin which is renewable, as long as the combustion does not smoky, does not cause soot, has a security advantage in terms of distribution, and not volatile. This study aims to characterize bioethanol gel product with variation of CMC, optimizing performance on bioethanol gel stove. This experiment was conducted by experimental and started with bioethanol gel making process with variation of composition of CMC 2, 2.5 gram. Characterization of bioethanol gel was done by testing the calorific value and residue. Application of bioethanol gel is done on bioethanol gel stove, performance optimization in this research is to increase the air-way (hole) with diameter 1 inch, and 2 inch. Parameters measured include thermal efficiency of combustion, specific fuel consumption, time to boil and power. Based on the results of research that has been done, it shows the calorific value of sample A 7058 kcal/kg, sample B 7260 kcal/kg, ash content of sample A 4.1%, sample B 5.1% as the burning performance of bioethanol gel stove with 1 inch diameter and 2 inch diameter of thermal efficiency value of combustion diameter of 1 inch 28% for 2 inch diameter 24%, specific fuel consumption diameter 1 inch 0.06 gr/gr water for 2 inch diameter 0.07 gr/gr water, power 1 inch diameter 3.3 kilowatt for 2 inch diameter 3.6 kilowatt, time to boil 1 inch diameter 11.5 min for 2 inch diameter 10.5 min.
