Cordierite/Corundum/Mullite-based Honeycomb Ceramic Heat Accumulation Substance
It's features of corrosion resistances, large specific surface area, small heat
Resistance, good thermal conductivity and excellent thermal-shock resistance, fast heat exchanging and energy saving. It's widely used in many fields.
The honeycomb ceramic as the heat exchange media is the key part for heat storing HTAC
( High Temperature Air Combustion) technology. It is the best choice for RTO, heat exchanger
And other environmental protection and energy saving products.
Characterics:
1. Low thermal expansion
2. Large specific heat capacity
3. High specific surface area
4. Low pressure drop
5. Small thermal resistance
6. Good thermal conductivity
7. Good heat-shock resisting ability
Application: Iron and steel, metallurgy, petrochemical, electric power, boiler and Fuel elecric plant, Thermal power plant, theheat power station etc.
