大型LNG低温储罐保冷标准与性能计算

Standard and Performance Calculation of Large-scale LNG Cryogenic Storage Tank

利用ANSYS软件对LNG低温储罐的罐底、罐壁及罐顶进行温度场的模拟,并将模拟结果和标准值进行对比验证。对罐底、罐壁及罐顶绝热部分进行数值模拟计算,最终得到保冷设计在保冷性能方面可以满足工程需要。

The temperature fields of the bottom, the wall and the roof of the LNG cryogenic storage tank are simulated using ANSYS software, and the simulation results are compared with the standard values. The results show that the insulation performance of the bottom, the wall and the roof of the tank can meet the engineering requirements.
