Ceramic Honeycomb with Hexagon Hole for Rto

Product Description > Honeycomb Ceramics Honeycomb ceramic heat recovery media is a key component of regenerative burner, which is widely used in iron and steel, machinery, building materials, petrochemicals, nonferrous metal smelting and other industries, furnace, hot air furnace, heat treatment furnace, cracking furnace, baking, melting furnace, both in the hot furnace, oil and gas boilers, and furnaces. The technique is to make two ceramic media beds alternating endothermic exothermic by reversing device. Most common applications include: RTO, (RCO), metal casting combustor, metal melting industrial furnace, etc.Compared with other ceramic media which have conventionally been used in RTOs. The advantages of honeycomb monolith include a greater thermal efficiency and a lower pressure drop across the heat exchanger bed. The increase in thermal efficiency and lower pressure drop generally results in smaller equipment design, lower capital cost and lower operating cost. Honeycomb ceramic serves as a more efficient alternative for the following reasons: cutting fan load for significant energy saving (low pressure drop owing to straight channels), less volume, thin wall thickness, faster in thermal exchange. Lighter weight, so less structural support is required. Above all, High specific surface area means high conversion efficiency in converters occupying small volumes. All these benefit, especially larger specific surface area make honeycomb ceramic the better performance media across industries.> MaterialsAlumina CeramicsAlumina Ceramics is the most widely used advanced ceramic material. Owing to its highly strong ionic inter-atomic bonding, alumina offers good performance in terms of chemical and thermal stability, relatively good strength, thermal and electrical insulation characteristics at a reasonable price. With a range of purities and also the relatively low cost in raw material production it is possible to utilize alumina for wide ranging applications across a variety of different industries.Mullite Ceramics Alumina Mullite occurs very rarely in nature because it only forms at high temperature, low pressure conditions, so as an industrial mineral, mullite has to be supplied by synthetic alternatives. Mullite is a strong candidate material for advanced ceramics in industrial process for its favourable thermal and mechanica properties: low thermal expansion, low thermal conductivity, excellent creep resistance, suitable high temperature strength and outstanding stability under harsh chemical environments.Dense Alumina & Dense CordieriteLow water absorbtion (0-5%)High density, High heat capacityLarge specific surface area, greater thermal efficiencyStrong anti-acid, anti-silicon, anti-salt. Low block rateSilicon Carbide CeramicsSilicon carbide is notable for its hardness, high melting-point and high thermal conductivity. It can retains its strength at temperature as high as 1400 °C and offers excellent wear resistance and thermal shock resistance. It has well-established and wide-spread industrial applications as catalyst supports and hot-gas or molten metal filters because of its low thermal-expansion coefficient and good thermal-shock resistance as well as excellent mechanical and chemical stability at elevated temperature environments.Cordierite CeramicsCordierite has a superior thermal shock resistance due to their intrinsic low coefficient of thermal expansion (CET), coupled with relatively high refractoriness and high chemical stability. Therefore, it is often used as high temperature industrial applications, such as: heat exchangers for gas turbine engines; honeycomb-shaped catalyst carriers in automobile exhaust system.Corundum Ceramics 1, high purity: Al2O3> 99%, good chemical resistance2, temperature resistance, long-term use at 1600 °C, 1800 °C short-term3, thermal shock resistance and good resistance to crack4, slip casting, high density, high purity aluminaMaterial:Corundum mullite, mullite Cordierite, Cordierite, mullite, zirconium mullite, silicon carbide composite, etcShape:Square, rectangle, circle, triangle, hexagonal hole, etcProduct Parameters   RTO/RCO honeycomb ceramics Main Size: L*W*G(mm) 150x 150 x 300(150) Number of Cell 25x25=625 40x40= 1600 43x43=1849 50x50=2500 60x60=3600 Width of Cell(mm) 4.95 3.02 2.81 2.38 1.98 Thickness of inner wall(mm) 1.0 0.7 0.65 0.6 0.5 Surface Area(m2/m3) 577 886 950 1084 1294 Opening Ratio(%) 68 65 65 63 63 RTO/RCO honeycomb ceramics Physical Properties: Item Aluminum Porceian-cordierite Dense aluminum porcelain Cordierite Mullite-Cordierite Mullite Enamel Density(g/cm3) 2.0~2.3 2.4~2.6 1.6~1.9 1.7~2.0 2.0~2.4 1.7~2.0 Bulk density (g/cm3) 0.65~0.8 0.65~0.8 0.6~0.7 0.65~0.75 0.65~0.8 0.65~0.75 Thermal Expansion Coefficient (X10-6°C-1) (RT-800°C) ≤6 ≤6 ≤3 ≤3.5 ≤5.5 ≤6.5 Specific heat capacity (J/Kg.k) 950~1150 1000~1200 900~1100 900~1100 1000~1150 900~1100 Thermal Conductivity (w/m.k
