摘要： PURPOSE:To reduce the steps for execution of works required on the spot, by prefabricating a heat shielding. CONSTITUTION:Tips of stud bolts 19 of a side section 5B and a bottom section 5C of a tank are projected through heat shielding materials 10 into recesses 12, and the panels 7, 8 are arranged on outer surfaces of the tank. After a synthetic resin washer 21 and a metal washer 22 are threaded onto each stud bolt 19, a nut 23 is threaded onto each stud bolt 19. A push plug 24 of the same material as the that for the heat shielding material 10 is inserted into each recess 12, and an aluminum pad 25 is stuck on an aluminum foil 11 to close each recess 12. A gap 20 is filled with a flexible fibrous heat shielding material, and the joint between panels 7, 8 is sealed up with an aluminum foil tape 26. Other heat shielding panels such as a top heat shielding panel and corner heat shielding panels are also attached in a similar manner.

摘要： PURPOSE: To reduce the temperature rise on the surface of liquid and the increase in the peressure of gas in a tank, by providing a baffle plate to diffuse a natural convection boundary layer produced on the inside of the wall of the tank of a presure-accumulation-type low-temperature liquefied gas tanker.
CONSTITUTION: A baffle plate 1, whose width (d) is larger than the thickness of a natural convection boundary layer (a) which is produced on the inside of the wall 2 of a tank, is provided in a prescribed position on the upper inside part of the wall 2 of the tank so that the baffle plate 1 extends almonst horizontally along the total circumference of the wall 2 at a prescribed distance down from the surface of liquefied gas fully fulled in the tank. As a result, the flow of the boundary layer (a) produced because of heat entering through the wall 2 is changed as shown by arrows A so that the layer (a) is mixed with the other portion of the liquid. The temperature of the boundary layer (a) reaching the surface of the liqid is much reduced due to the baffle plate 1. Since the temperature of the relatively warm layer staying on the surface of the liquid is thus reduced, the rise in the pressure of gas in the tank is diminished.

摘要翻译：目的：为了减少液体表面的温度上升和罐内气体的增加，通过提供挡板来扩散在储罐内壁上产生的自然对流边界层，蓄能式低温液化气罐车。构成：其宽度（d）大于在罐的壁2的内侧产生的自然对流边界层（a）的厚度的挡板1设置在上侧的规定位置使得挡板1沿着壁2的总圆周水平延伸，从罐中完全充满的液化气体的表面向下延伸规定的距离。结果，由于通过壁2进入的热而产生的边界层（a）的流动如箭头A所示地变化，使得（a）层与液体的另一部分混合。由于挡板1，到达液体表面的边界层（a）的温度大大降低。因此，滞留在液体表面上的较热层的温度因此降低，因此，坦克中的气体减少了。
