摘要
在热力学第一定律基础上,对LNG船的双燃料电力推进装置及其余热利用系统建立了热效率模型,并计算了某型LNG船的主机系统热效率。结果表明,双燃料电力推进系统的热效率远高于传统蒸汽动力系统,余热回收系统提供了丰富的热能和电能。热效率模型为LNG船动力系统的设计选型及节能改造提供理论依据。
According to the first law of thermodynamics,this paper establish a thermal efficiency model of the dual-fuel electrical propulsion unit and its waste heat recovery system. This paper also calculates one type of LNG carrier's thermal efficiency. The results show that the dual-fuel electrical propulsion system's thermal efficiency is much higher than the traditional steam power one's. The waste heat recovery system provides adequate heat and electrical resources. The thermal efficiency model can provide theoretical basis for LNG carriers' design,equipment selection and energy saving transformation.
