Honeycomb Ceramic Monolith Charactor:
1)It has advatange of high surface area, high heat capacity, low thermal expension, corrosion resistant and temperature
resistance, widely use in chemical, metallurgical, gas and environmental protection industries. Main application are:
a.Tower packing-high surface area, uniform distribution fluid, high efficiency of mass transfer.
b.Catalyst carrier-reduce the oxidation temperature of VOA in purification of industrial exhaus gas.
c.Thermal regenerative packing-good heat capacity, saving energy 40-70%in RTO system.
d.Gas combustion distributing pl ate-distribute uniformly and make the combustion complete, saving energy more than 10%
e.refractory kiln furniture-low bulk density, good thermal efficiency.
