Hlavním teplonosným médiem modulu z keramických vláken je plyn a poréznost keramického vlákna dosahuje více než 90 procent. Složení plynu v pórech přímo ovlivňuje tepelnou vodivost keramického vlákna. Přenos tepla keramického vlákna je logaritmická křivka a hodnota tepelné vodivosti roste rychleji, když je teplota vyšší než 700 stupňů.
The steady-state heat transfer of ceramic fiber lining is mainly based on the heat insulation of the furnace wall or heat insulation. The thermal conductivity of refractory fiber is small, and the heat resistance through such a furnace lining is relatively large, and the heat dissipation loss can be significantly reduced. The non-steady state heat transfer of refractory fiber lining is mainly based on reducing the heat storage of the lining. The intermittent heating furnace frequently raises and lowers the temperature, most of the time in the heating 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.
