Design and Optimization of LNG Heating System for Dual-fuel RoPax Vessel
Selection and logical control of LNG heat sources directly affect the safety and economic operation of liquefied natural gas(LNG)fuel ships.This article takes a dual fuel RoPax vessel as the example to introduce the heat source selection,principle design,logical control,and system optimization of the LNG heating system.Verification shows that the optimized water glycol heating system has stable water temperature,and the optimized heat exchange area of the equipment is more conducive to the layout of the cabin equipment.As the system has higher redundancy it is safer and more reliable.The new system design can significantly reduce the construction cost and operational energy consumption of ships.
