<p>The present invention contemplates the use of a compressed ceramic fiber blanket insulation (36) held in place in the domed portion of a vessel (14), with a plurality of curved ribs (30), or alternatively, the combination of curved ribs and a wire mesh (34). Such arrangement is preferable for holding fiber blanket insulation material over possible alternate methods for securing it since the thermal expansion of the ribs at elevated operating temperature of the vessel is designed to progressively compact the blanket lining to counteract any fiber shrinkage or associated expansion of the metal shell casing.</p> |
