| 摘要 |
The invention relates to a sealed, thermally-insulating tank for containing LNG, comprising two sealed barriers and two insulating barriers (2, 4), wherein the secondary insulating barrier (2) comprises a first set of thermally insulating elements (11) juxtaposed so as to form a first layer, and a second set of thermally insulating elements (10) juxtaposed so as to form a second layer located between the first layer and the supporting structure. Each of the thermally insulating elements (11) of the first layer comprises a casing filled with an insulating lining essentially consisting of inorganic wool, organic wool, low-density (less than 50 kg /m3) polymeric foam, or an aerogel. Each of the thermally insulating elements (10) of the second layer comprises a block of high-density polymeric foam. |
