HEAT INSULATION MATERIALS

INDUSTRIAL FURNACE EFFICIENCY

Heat Insulation Materials

Heat insulation materials are foundational to industrial furnace efficiency, marked by their low thermal conductivity and minimal heat capacity.

The strategic use of these materials significantly reduces energy consumption and CO₂ emissions, and optimizes the external wall temperature of furnaces.

Standard heat-insulating materials include insulating refractory bricks, plates, castables, and ceramic fiber materials. It's important to note that the thermal conductivity of these materials hinges not only on their total porosity but also on factors like pore size and mineralogical composition.

Advanced aggregates based on calcium hexaluminate (CA₆), known for their reduced thermal conductivity compared to similar-density materials, are at the forefront of innovation in this field.

Moreover, micro-porous heat-insulating materials can achieve thermal conductivity levels at high temperatures that are superior to those of lower density fiber products.
