The main heat transfer medium of the ceramic fiber module is gas, and the porosity of the ceramic fiber reaches more than 90%. The gas composition in the pores directly affects the thermal conductivity of the ceramic fiber. The heat transfer of ceramic fibers is a logarithmic curve, and the thermal conductivity value rises faster when the temperature is higher than 700 degrees.
The steady-state heat transfer of ceramic fiber lining is mainly based on furnace wall insulation or thermal insulation. The unsteady heat transfer of the refractory fiber lining is mainly to reduce the heat storage of the lining. The intermittent heating furnace frequently rises and falls in temperature, and most of the time is heating the furnace wall. Due to the low heat storage of the ceramic fiber lining, the heating and cooling time of the furnace is greatly shortened, and a large part of the heat is saved.
As a lightweight refractory material, ceramic fiber modules are suitable for most high-temperature heating equipment. It has many advantages, such as low thermal conductivity, good thermal insulation performance; high refractoriness, wider application environment; lightweight refractory material, reducing furnace load; good thermal shock resistance, long service life; convenient construction, no need for oven, Save the time of laying the furnace; the key is to have good energy-saving effect, reduce fuel loss and save costs.
