摘　　要：根据LNG储罐的结构,给出储罐热流量和静态蒸发率的计算方法。利用该方法对济南某3×10^(4)m^(3)双金属LNG储罐热流量和静态蒸发率进行计算,分析储罐热流量的影响因素。结果表明:案例储罐的静态蒸发率为0.0748%,静态蒸发率较小,储罐的保冷性能良好。环境温度对储罐热流量的影响较大,环境风速和充满率对储罐热流量的影响较小。According to the structure of LNG storage tank,the calculation method of storage tank heat flow rate and static evaporation rate is given.The heat flow rate and static evaporation rate of a 3×10^(4)m^(3) bimetallic LNG storage tank are calculated by this method,and the factors affecting the heat flow rate of the storage tank are analyzed.The results show that the static evaporation rate of the case storage tank is 0.0748%,the static evaporation rate is small,and the cold insulation performance of the case storage tank is good.The environmental temperature has a greater impact on the heat flow rate of the storage tank,the environmental wind speed and filling rate have a small impact on the heat flow rate of the storage tank.
