China Cordierite Honeycomb Monolith Ceramic for Heater 150*150*300mm

Ceramic Honeycomb Heat Storage Substrate:
Ceramic Honeycomb Heater is supplied for Regenerative Thermal Oxidisers (RTOs). It is also used as a support for a catalyst bed or a bed of random ceramic saddles. An RTO is an industrial process for the treatment of contaminated air streams by incineration (oxidation). Such systems provide a highly efficient and cost effective method for the removal of volatile organic compounds (VOC) and other hazardous air pollutants. In an RTO system, ceramic material is used to provide a "heat sink" whereby heat is absorbed from the exhaust gas which then is used to preheat the incoming gas stream. High energy efficiency, approximately 95%, is achieved by recovering and re-using the excess heat energy which is created during the combusting of organic materials. Ceramic honeycomb packing is normally supplied in porous cordierite material. It is also available in other materials such as high alumina or porcelain.
Material:
Corundum-mullite, Cordierite-mullite, Cordierite, Mullite, Corundum, Zirconium- mullite etc.
With the development of High Temperature Air Combustion Techonolog, honeycomb ceramic has been widely used in filelds of smelting metallurgy petrochemical electric powerboilerand so on. Our company has researched and developed a series of honeycomb ceramics for heat storage according to the different features of industrial furnaces. Our own research and developed honeycomb ceramic has characteristics: Large surface arealow pressurestrong heat storagelow average linear expansionstrong corrosion resistance against acid and alkali and so on. Also we can supply the products as per the customers' requirements.
Ceramic Honeycomb Heater (Regenerator) can be also used as the flue gas waste heat recovery and high efficient combustion and low NOX emission in metallurgy, Chemical industry, building material industry, chemical plant, metallurgical plant, the power of industry boiler, gas turbine, engineering of heating equipment of high temperature storage, heat transfer system of industrial waste gas treatment.
