선박 연료유 시험을 위한 30L급 소형 보일러 장치의 개발 Development of 30 Liter Small Boiler for Testing Marine Fuel Oil
pp.223-228
The fuel oil used for ships has the viscosity higher than the fuel used for general vehicles and contain impurities, so it’s exhaust gas results in the environment pollution. There have been studies actively conducted to examine alternative fuels for improving the quality of the marine fuel oil. It is, however, necessary to test the quality of fuel for mega ships, by conducting the simulation test using reduced-size models, before the demonstration step, because it takes too much cost and time to directly perform the demonstration of alternative fuels. This study, therefore, developed a 30-liter small-size boiler similar to the ship system and performed an initial fuel test by applying MGO to it. The findings show that the amount of nitrogen oxide to which 4% of the standard oxide level was applied was about 24.69ppm, when the oxide level was 10.02%, with the CO2 of 8.02%, the exhaust gas temperature of 291.15℃ and the combustion efficiency of about 74.53%, indicating that it will be necessary to conduct various studies through the ratio control in the future.
