Product Description

Honeycomb ceramic as heat exchange media is the key part for heat storage HTAC (High Temperature Air Combustion) technology, which has been widely applied in all kinds of pushing-steel heating furnace, RTO(Regenerative Thermal Oxidation), stepping heating furnace, heat treatment furnace, forging furnace, dissolving furnace, steel wrapping/middle wrapping baking apparatus, soaking pit, radiation tap incendiary apparatus, covering furnace, high temperature hot-blast stove in metallurgical machine building and all kinds of ceramic cellar stove, glass cellar stove in building materials, and all kinds of tap heating stove, splitting stove, other industrial stove cellar, too. Honeycomb ceramics as heat storage body, by the advantage of large specific surface area, small heat resistance, good thermal conductivity, excellent thermal shock resistance, realize quickly exchanging heat; Reducing energy in the strict sense (up to 97% of true thermal energy can be recovery and also it can absorb NOx more than 40%).



Honeycomb Ceramic Heater advantages:
*High working temperature.
*Large specifc surface area.
*Good thermal conductivity.
*All shapes avalible.

We can provide high quality honeycomb ceramic parts. Because of it's features of corrosion resistances, large specific surface area, small heat resistance, good thermal conductivity and excellent thermal-shock resistance, fast heat exchanging and energy saving. It's widely used in many fields. Honeycomb ceramic as the heat exchange media is the key part for heat storing HTAC ( High Temperature Air Combustion) technology. It is the best choice for RTO, heat exchanger and other environmental protection and energy saving products. Honeycomb ceramic carrier used high aluminum cordierite as raw material forming the main board or circular honeycomb ceramic carrier, coated with special catalyst, make it have the advantages of special strength, toughness, vibration resistance, heat resistance, so the product can remove oil, harmful gas from chemical production, filter liquid waste in the process of petroleum, chemical industry, so as to improve the product quality.

Honeycomb ceramic regenerator heat capacity more than J/kgk1000. Use a temperature≥ 1700° C in the heating furnace, roaster, soaking furnace, pyrolysis furnace, fuel can be savings of more than 40%, increase in production for more than 15%. The flue gas temperature below 150° C.

With the development of High Temperature Air Combustion Techonolog, honeycomb ceramic heater has been widely used in filelds of smelting metallurgy petrochemical electric powerboilerand so on. We have researched and developed a series of honeycomb ceramics for heat storage according to the different features of industrial furnaces.
