To answer this question, let’s first understand the thermal insulation principle of ceramic fiber module.
Ceramic fiber is a lightweight refractory and thermal insulation material. Its thermal insulation comes from its ultra-low thermal conductivity, which is due to its diameter of 3 μ The convective heat transfer of pores below m is very small, and almost no air flow can be formed, while the porosity of ceramic fiber module can reach more than 96%.
This is the advantage of refractory fiber. Once applied to high-temperature water vapor environment, the advantage will be instantly converted into disadvantage. This is because the pores inside the fiber will be filled with water molecules, so that the ceramic fiber eroded by water becomes the best heat conductor. The heat is transmitted to the steel plate or furnace wall through water, ranging from heat loss to steel plate deformation and furnace body damage, which seriously affects the production safety.
Therefore, ceramic fiber modules cannot be used in high-temperature water vapor environment. Similarly, aluminum silicate fiber modules that are damp or wet should also be discarded. During the storage and transportation of ceramic fiber modules, corresponding rainproof and moisture-proof facilities shall also be adopted.
