Ceramic Fiber Insulation
Ceramic fiber insulation has been used since the 1950s in various forms such as fireproof cotton, fireproof board, fireproof paper, fireproof blanket, and ceramic block.
The raw material for making these ceramic fiber insulation is kaolin, which is known as white clay.
Until the 1980s, factories that used steam boilers used refractory materials such as firebricks as thermal insulation.
Ceramic engineers discovered that if clay is heated to very high temperatures, it melts and, as it cools, forms fibers and small grains called shot. So, using these fibers, they were able to produce ceramic insulators that could withstand temperatures up to 1,700 degrees.
The use of ceramic insulators is different in each industry. Below we will discuss some of the uses of ceramic insulators.
1- Ceramic fiber insulation in power plants
Energy industries use boilers to generate electricity, ceramic fibers are used to insulate heaters located at the top or bottom of the boiler. To prevent its temperature from dropping below 450 degrees, a 1-inch thick ceramic blanket (25 mm blanket) is used.
The turbines that generate electricity have a temperature of about 540 degrees, and ceramic insulation is used to prevent heat loss.
2- Ceramic fiber insulation in the steel and casting industries. Refractory materials, insulating bricks, and ceramic fibers are among the most widely used items for the construction and repair of furnaces used in this industry. Some of the applications of ceramic fibers in the steel and casting industries are as follows:
Use of refractory fibers in coke ovens and coal to produce carbonaceous coal as a fuel for furnaces
Use of refractory fibers in blast furnaces to melt lime and iron ore
Use of refractory fibers in smelting furnaces, such as electric arc furnaces, coupler furnaces, open blast furnaces to separate smelting impurities and slag.
Other applications of ceramic insulation include the following:
• Sealing and sealing of furnace doors using rope or ceramic packing
• Using petroceramics for welding and heat treatment of pressure vessels
Ceramic insulation has been used for about 75 years and is still the best choice at high temperatures.
These ceramic fibers are produced in various shapes and forms such as cotton or bale, blanket, paper, plate or board, module, fabric, tape, etc.
You can purchase ceramic insulators for your use in various forms through Naroon Kala Tadbir Company.
