Description
High surface area, large heat capacity,
low thermal expansion, resistant to
corrosion and high temperature, ceramic
honeycomb monoliths have been well used
in chemical, metallurgical, gas and
environmental protection industries.
The main usage is as follows:
● Tower packings - With high surface
area, even distribution of fluid and,
efficient in mixture separation in chemical
& petrochemical industries.
● Catalyst carriers - Reduce the oxidation
temperature of VOC in purification of
industrial exhaust gases in RCO systems
and automobiles.
● Regenerative heat step - up transformer
- Large heat capacity, low resistance
to fluid and, energy saving up to 40～70%
in RTO systems.
●Gas combustion distributor - Distribute
the heat uniformly, and make the combustion
completely, It can save energy more
than 10%.
● Kiln furniture in refractory industries
- Low bulk density and high thermal
efficiency. |
