In this study, emulsified fuels were prepared and produced by blending 0%, 5%, 15%, and 25% water with Bunker C oil to reduce the amount of air pollution emitted by ships and replace oil resources, and they were applied to an actual marine boiler to analyze the exhaust gas. The fuel effects on the improvement in exhaust gas emissions were as follows: The oxygen (O₂) concentration increased by up to 4.2%, and that of carbon dioxide decreased by approximately 2.1%. Under the standard O₂ concentration of 4%, the concentration of nitrogen oxides decreased by up to 31.41%, and that of sulfur oxides decreased by up to 37.47%. However, the exhaust gas temperature decreased by approximately 14.3%, and the combustion efficiency decreased by approximately 2.6%. Comparing the emission improvements, the combustion performance of the emulsified fuels was close to that of the conventional Bunker C fuel. These results indicate that the application of water-emulsified fuels to a marine boiler can reduce the amounts of certain air pollutants.

用于船用锅炉的水/燃料舱C油乳化燃料的废气排放改进

在这项研究中，乳化燃料是通过将0％，5％，15％和25％的水与Bunker C油混合制备和生产的，以减少船舶排放的空气污染量并替代石油资源，并将其应用于实际的船用锅炉要分析废气。燃料对改善废气排放的影响如下：氧气（O ₂）浓度增加了多达4.2％，二氧化碳的浓度减少了约2.1％。在标准O _2下浓度为4％时，氮氧化物的浓度最多降低31.41％，硫氧化物的浓度最多降低37.47％。但是，排气温度降低了约14.3％，燃烧效率降低了约2.6％。比较排放物改善后，乳化燃料的燃烧性能接近常规的Bunker C燃料。这些结果表明，将水乳化燃料应用于船用锅炉可以减少某些空气污染物的数量。
