摘　　要：氨燃料作为一种零碳燃料,在国际船舶行业上受到广泛关注,具有广阔的市场前景。由于氨在标准大气压下的沸点为-33℃,而且可以使用多种存储方式,使其容易在液态下进行运输。文章对不同C型液氨燃料舱设计方案的材料成本进行对比分析,得到材料成本最低的设计方案。结果表明:对于容积不超过2000 m^(3)的燃料舱,采用低温低压存储方式下,碳锰钢燃料舱材料成本最低;对于容积3000 m^(3)及以上的燃料舱,采用低温低压存储方式下,含镍量不超过5%的低镍钢燃料舱材料成本较低;对于氨燃料预留的LNG动力船舶,其C型燃料舱宜选择S30408等低温不锈钢。As a zero-carbon fuel,ammonia fuel has received extensive attention in the international shipping industry and has broad market prospects.Since ammonia has a boiling point of-33℃at standard atmospheric pressure and can be stored in a variety of ways,it is easy to transport in the liquid state.The paper compares and analyzes the material costs of different C-type liquid ammonia fuel tank design options to obtain the design option with lowest material cost.The results show that for fuel tanks up to 2000 m^(3)in volume,carbon manganese steel fuel tanks with low temperature and low pressure storage have the minimum material costs.For fuel tanks of 3000 m^(3)and above in volume,low nickel steel with a nickel content of up to 5%fuel tanks with low temperature and low pressure storage have less material costs.For LNG powered ships reserved for ammonia fuel,low temperature stainless steels such as S30408 are preferred for the C-type fuel tanks.
