掺混生物燃料油对低速机燃烧排放性能的影响Impact of blending biofuel oil on combustion emission performance of low-speed engines
摘要
为促进船用生物燃料油在船舶领域的推广和使用,通过实船试验比较了B24船用生物燃料油和传统船用低硫燃料油(VLSFO)在大型船舶上的燃烧性能和排放性能。结果表明:B24和VLSFO的燃烧性能偏差不超过3%;B24和VLSFO的CO2、NOx和CO排放量基本持平,且NOx排放量均保持在MARPOL公约附则Ⅵ Tire Ⅰ限量下;B24的全生命周期碳排放量相比VLSFO减少19%。综上,B24船用生物燃料油在碳减排方面具有优势,并同时兼顾了动力安全性。 To promote the promotion and application of marine biofuel oil in the maritime sector, full-scale ship trials were conducted to compare the combustion performance and emission performance of B24 marine biofuel oil and traditional very low sulfur fuel oil (VLSFO) on large ships. The results showed that the deviation in combustion performance between B24 and VLSFO did not exceed 3%. The emissions of CO2, NOx, and CO from B24 and VLSFO were basically the same, and the NOx emissions of both remained below the limit of MARPOL Annex Ⅵ Tire Ⅰ. The full life cycle carbon emissions of B24 were 19% lower than those of VLSFO. In conclusion, B24 marine biofuel oil has advantages in carbon emission reduction while maintaining the required power performance and optional safety.
