ShreeCera-: In the layered construction (Blanket, Board and Moist pack) the anchors are exposed to hot face temperature and are limiting factors for use of Ceramic fiber in high temperature applications. To overcome this limitation, modules are used. Module anchoring systems can provide an option of backup blanket lining with hot face modular lining. A backup blanket lining serves as safety lining in all unlikely event of module failure. It also makes it convenient to provide vapour barrier for protection against attack of sulphurous gases on the furnace shell.
