摘　　要：基于氨燃料在船舶上应用的需求,针对采用奥托循环的氨发动机设计氨燃料供给系统,该系统主要包括氨蒸发气处理和液态氨蒸发两部分。基于HYSYS进行氨燃料供给系统流程模拟,模型中植入液氨储罐、阀门、分离器、压缩机和换热器等设备模块,其中,氨的物性计算采用Peng-Robinson模型,水乙二醇的物性计算采用NRTL模型。稳态模拟结果可以反映每个设备进出口物流的压力、温度和流量状态,以及给出相关设备的参数。动态模拟结果有效验证了通过控制泵转速来控制进机压力的可行性。研究成果可对氨燃料供给系统的设备选型、系统流程优化和控制系统设计提供支持。Based on the need for ammonia fuel in the application of ships,an ammonia fuel supply system(AFSS)is designed for an Otto cycle ammonia engine,which mainly includes two parts:ammonia BOG handling and liquid ammonia evaporation.AFSS process simulation is based on the HYSYS software and involves incorporating equipment modules such as liquefied ammonia storage tanks,valves,separators,compressors,and heat exchangers into the model.The Peng-Robinson and NRTL models are used to calculate ammonia and water-ethylene glycol thermophysical properties,respectively.The simulation results can show the pressure,temperature,and flow status at the inlets and outlets of each equipment and provide parameters for related equipment.The dynamic simulation results effectively verify the feasibility of controlling the pressure entering the engine by controlling the pump speed.This work can support the selection of equipment for the AFSS and the optimization design of the system process.
