Fiberfrax® Fiberwall® Bonded module systems are used as a full-thickness, mechanically anchored lining, or as a hot face veneer over existing refractory surfaces in suitable condition. Bonded modules are typically mortared into place over existing refractory using .908 kg to 1.36 kg (2 to 3 Ibs) of Fiberstick™ refractory cement per module. This lining over refractory (or veneering) approach not only increases the efficiency of the refractory lining but helps to protect it from further degradation.
A ceramic fiber veneer is often a more financially attractive alternative than completely relining a unit due to the lower installation cost and shorter downtime.
Advantages of Fiberfrax Ceramic Fiber Veneer:
Fiberwall Bonded modules are constructed with folded and tightly compressed Durablanket® S, Durablanket HP-S or Durablanket 2600 ceramic fiber blanket. They are available in a range of densities and thicknesses to match a wide variety of thermal requirements in applications up to 1260°C (2300°F). At high temperatures, this folded construction takes advantage of the inherent shrinkage present in all ceramic fiber blanket products by causing the layers at the hot face folds to seal against one another, thereby preventing heat flow to the shell.
