초록
Due to severe environmental pollution from ships, IMO(International Maritime Organization) is imposing strict controls on pollutant emission in ECA(Emission Control Area). There have been active studies to find fuel that could replace existing fossil fuel and especially in recent times, diverse studies on recycling of coffee ground are in progress. The annual domestic consumption of coffee was 150,000 tons according to the data of 2017 year and 99% of them are coffee ground to be scrapped. Therefore, in this study, coffee ground was mixed with diesel oil to develop alternative fuel. The analysis result showed that when coffee ground and diesel oil were mixed at a rate of 30%, 20% and 10%, the diameter of coffee ground droplet was 49.1μm, 45.9μm and 17.5μm respectively.
