Our ceramic honeycomb for heat exchange includes ceramic honeycomb heat recovery bed, heat exchange bed, thermal storage & recovery ceramic media, heat exchange elements / media. Ceramic monoliths media evidently save energy in steel works, metallurgic industry, and also egenerative thermal oxidizers (RTO). Honeycomb monolith is the key components of the style furnace, it is extensively used in many kinds of heater, sirocco furnace, heat treatment furnace, cracking column, roaster, melting furnace, balance heating stove and etc. This technology can save more than 40-70% of energy. . The material for heat exchange media honeycomb ceramic can be cordierite, mullite ceramic, alumina, aluminum titanate etc. Customer can choose the suitable materials according to its application.1.chemical composition: CompositionAlumina CeramicMulliteCordierite DenseCordierite PorousStonewareSiO2 42.827.847.847.970.2AI2O350.570.135.133.719.4MgO--8.5-9.512-130.18Fe2O30.50.80.781.00.5Na O2+K o2+Ca O4.81.02-2.51.033.3TiO2+BaO--0.390.780.25High Aluminum Al2O3>90%Al2O3>90%High Silicon SiO2>98%SiO2>98%2.Speciality & Sizes:Quantity of ChannelsChannel density (cm2)Width of channel (mm)Specific surface area(m2/m3)Hole fraction (%)5x5126.31177713x135(1)9.22786420x2011(2)6.44557325x2518(3)4.95406740x4046(7)3.08256550x5072(11)2.31005573.Physics performance:PerformanceUnitsAlumina CeramicMulliteCordierite DenseCordierite PorousStonewareDensityg/cm3 2.72.12.47 1.92.3-2.4The hot coefficient of expansion 20-100010-6/K-15-64.5-52-2.51.5-1.84-7Heat capacity 20-1000J/kgk800-900850-1050800-1200750-800840-920Heat resisting assaultingk150350250300250The highest using temperature14001600130012001100
