The honeycomb ceramic can be used as the heat exchange media,which is a new-developing industrial ceramic,honeycomb ceramic heataccumulation substrate has low heat expansion coefficient, largesurface area, good heat stability and anticorrosion. Such productsare widely applied in rubbish incinerator, industrial waster gasdisposal and high temperature storage and exchange for metallurgy,chemical and construction material industries.Typicalapplications:high temperature heat accumulation and exchange inindustrial waste gas treatment for metallurgical,chemical andconstruction material industries
1.Nox purification system in the smoke of the thermal powerplant;2.The harmful gas purification system in rubbish burning;
3.Poison gas purification system in chemical and mining industries.The slag filter for casting production in the metallurgicalindustry, The catalyst substrate,Stuffing material for chemicalindustry columns and Contact combustionThe honeycomb ceramic asheat exchange media is the major part for HTAC( High TemperatureAtmosphere Combustion) technology in industrial kiln. Theadvantages for using honeycomb ceramic as heat exchange media arefor HTAC technology as below: 1.Low thermal value blastfurnace coal gas can be used 2.More than 40% energy can besaved 3.More than 50% polluted materials in released smoke canbe reduced.The material for heat exchange media honeycomb ceramiccan be cordierite, mullite ceramic, alumina, aluminum titanate etc.Customer can choose the suitable materials according to itsapplication. 1.chemical composition:
