Keraamisen kuitumoduulin päälämmönsiirtoaine on kaasu, ja keraamisen kuidun huokoisuus saavuttaa yli 90 prosenttia. Huokosissa oleva kaasukoostumus vaikuttaa suoraan keraamisen kuidun lämmönjohtavuuteen. Keraamisen kuidun lämmönsiirto on logaritminen käyrä ja lämmönjohtavuusarvo nousee nopeammin, kun lämpötila on yli 700 astetta.
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.
