At present, most common industrial furnace insulation uses full ceramic fiber furnace linings, except for furnace types with wear, high wind speed or complex chemical composition. The reason why ceramic fiber is chosen is its high temperature resistance and light weight. In addition, ceramic fiber furnace lining can effectively reduce the surface temperature of furnace parts, reduce fuel consumption losses, improve product quality and output, and extend the service life of the furnace. .
As for the ceramic fiber structure of the kiln lining, I still prefer the combination of ceramic fiber module and blanket.
Industrial furnace lining uses full ceramic fiber lining. Fibers of different materials must be selected for each layer according to the principle of temperature gradient drop of the furnace lining, so that it can be economical and reasonable, and can effectively reduce costs.
The ceramic fiber blanket layer structure mostly uses steel plate welding anchor nails. The ceramic fiber blanket is fixed to the furnace wall layer by layer through screw rods, and is covered with stainless steel mesh to prevent falling. However, it is difficult to install multi-layer composite ceramic fiber blankets by hand.
Especially if there are more than 3 materials, manual installation is more difficult. First, the quality of construction cannot be guaranteed, and second, the integrity of multi-layer composites is poor.
If the lower temperature ceramic fiber blanket is tiled and the ceramic fiber module is installed on it, the structure is relatively strong. The preloaded elastic design compensates for the shrinkage of the fiber itself and strengthens the sealing of furnace lining . Overall The flatness and appearance are good, and the design of spraying curing agent on the working surface prevents slag from falling off and prolongs the service life of the furnace lining.
The structural advantages of ceramic fiber modules and flat blankets are reflected in the following aspects:
1, reduced fuel consumption and increased output.
2. The surface temperature of the furnace body drops.
3. The life of the furnace is extended.
4. The combustion loss is reduced.
