重庆-上海散货船混合动力推进方案分析

Comparison of Hybrid Propulsion Schemes for Bulk Carriers in Chongqing to Shanghai Section

针对长江重庆-上海散货船航行工况多变,柴油机直推方案存在主机负荷率低、油耗高、排放差等问题,进行直推方案、油电混合动力推进方案、油电气混合动力推进方案的综合技术性能及经济性比较分析,认为油电气混合动力推进方案具有经济性、节能减排的社会效益。

In view of the changeable sailing conditions of bulk carriers in the Chongqing-Shanghai section of the Yangtze river,the diesel engine direct push scheme has problems such as low main engine load rate,high fuel consumption and poor emissions.The comprehensive technical performance and economic performance of direct propulsion scheme,the oil-electric hybrid scheme,the oil-electric and LNG hybrid system scheme were compared and analyzed,it was found that the oil-electric and LNG hybrid system scheme is more economical and has social benefits of energy saving and emission reduction.
