Product Details
Insulating Board Ceramic Fiber Refractory For Combustion Chamber
Liners , Boilers , Heaters

Description:
Laurel ceramic fiber board is a lightweight refractory material
processed with alumina-silica fibers for applications at
temperatures up to 1430℃(2600℉)
Ceramic fiber board is a vacuum formed product that resists higher
gas velocities than ceramic fiber blanket,it is ideal for
furnace,boiler duct and stack lining due to its low thermal
conductivity and low heat storage allowing shorter cycle times and
quicker access for maintenance
Features
- Low thermal conductivity,saves fuel
- Very low heat storage,faster heat and cool-down reducing cycle
times
- Ligh weight.replaces heavy back-up insulation.less steel required.
- Excellent thermal shock resistance
- Resistant to hot gas erosion
- Resists most chemical attacks
- Easy to cut,handle and install
- Low sound transmission
- Resists penetration by molten aluminum and other non-ferrous metals
- Contains no asbestos


Applications:
- Refractory lining for industrial furnaces in
walls,roofs,doors,stacks,etc.
- Combustion chamber liners,boilers and heaters
- Back-up insulation for brick and monolithic refractories
- Transfer of molten aluminum and other non-ferrous metals
- Expansion joint boards
- Barrier against flame or heat
- Hot face layer for high velocity or abrasive furnace atmosphere
