The invention discloses an ammonia fuel ship SOFC/GT/SCO2/ORC/KC hybrid power system based on tail gas and anode exhaust coupling utilization, which is characterized in that liquid ammonia is heated, gasified and compressed by an ORC cycle working medium, first turbine exhaust and an SCO2 cycle working medium, then is cracked by an ammonia gas cracker and then is fed into an anode of an SOFC, and compressed air is heated by the SCO2 cycle working medium and then is fed into a cathode and a post-combustion chamber of the SOFC; exhaust gas of an anode of the SOFC serves as a heat source of SCO2 circulation, KC circulation and ORC circulation and then is jointly fed into a post-combustion chamber together with exhaust gas of a cathode of the SOFC, and the exhaust gas obtained after combustion in the post-combustion chamber passes through an SOFC/GT hybrid power subsystem of a first turbine; exhaust gas of the anode of the SOFC and exhaust gas of the first turbine serve as heat sources of the SCO2 circulation subsystem, the KC circulation subsystem and the ORC circulation subsystem, and liquid ammonia serves as a cold source of the SCO2 circulation subsystem and the ORC circulation subsystem and cools the exhaust gas of the first turbine. Heat energy of SOFC tail gas and anode exhaust gas and cold energy of liquid ammonia are utilized in a gradient mode, and the overall energy efficiency of the system is improved.

    本发明公开了一种基于尾气和阳极排气耦合利用的氨燃料船舶SOFC/GT/SCO2/ORC/KC混合动力系统,包括由液氨经ORC循环工质、第一涡轮排气和SCO2循环工质加热气化并压缩后通过氨气裂解器裂解送入SOFC的阳极,压缩空气经SCO2循环工质加热后送入SOFC的阴极和后燃室,SOFC的阳极的排气作为SCO2循环、KC循环和ORC循环的热源后与SOFC的阴极的排气共同送入后燃室,后燃室燃烧后排气经过第一涡轮的SOFC/GT混合动力子系统;SOFC的阳极的排气和第一涡轮排气作为SCO2循环子系统、KC循环子系统和ORC循环子系统的热源,液氨作为SCO2循环子系统和ORC循环子系统的冷源以及冷却第一涡轮排气。本发明梯级利用SOFC尾气、阳极排气的热能和液氨的冷能,提高系统整体能效。
