| 摘 要： | 根据船舶柴油机燃烧产物组分和C、H、O原子守恒规律,首次在空燃比计算模型中直接使用干气体浓度进行计算,并提供了湿气体浓度的修正公式,从而建立排气质量流量计算模型计算碳排放。通过计算与MARPOL公约附则VI修正案(2011)中的简单碳平衡法作了比较分析。最后通过实验验证该计算模型的正确性。因此该计算模型对法规的完善、船舶设计能效管理和船舶营运排放控制有较大的指导意义。

| Abstract: | In this paper, according to marine diesel engine combustion product components and law of atom conservation of C,H and O, it is the first time for the calculation model of air-fuel ratio to calculate in the direct use of the dry gas concentration, and provides the correction formula of the wet gas concentration, thus calculation model of the exhaust mass flow is established to calculate carbon emissions. Through the calculation, a comparative analysis is made to the simple method of carbon balance calculation with MARPOL annex VI amendment (2011) of the convention. Finally, its correctness is verified through experiment. Therefore, the calculation model is a certain reference value to develop regulations, and it also is helpful to the energy efficiency management in designing ship and emission control in ship operational management. |
