| Abstract: | 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 3×104m3 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. |
