LNG动力渔船冷能梯级利用

Cold Energy Cascade Utilization of LNG Powered Fishing Ship

在目前LNG船舶运行中,LNG气化过程所释放的大量高品位冷能往往未加利用而直接被带走,极大地浪费了LNG燃料冷能。同时,LNG渔船上对诸如渔货冷藏冷冻、船舶空调系统、发动机及设备冷却之类的冷能需求十分巨大。为解决上述矛盾,文中提出LNG动力渔船流化冰制取系统,以期对LNG冷能回收再利用,既高效利用能源又节能环保。

In the current LNG ship operation,a lot of high-grade cold energy released in the LNG gasification process is often taken away without being utilized,which wastes the cold energy of LNG fuel greatly.At the same time,there is a huge demand for cold energy on LNG fishing boats,such as fish refrigeration,ship air conditioning system,engine and equipment cooling.In order to solve the above contradiction,this paper proposes a fluidizing ice making system for LNG powered fishing boats to recycle the cold energy of LNG,which not only uses energy efficiently but also saves energy and protects the environment.
