Thermal Store Cordierite Honeycomb Ceramic for Heater Exchange
Product Description
Honeycomb ceramic heater is composed of countless equal holes. The structure of it is like honeycomb shape and it is a kind of new ceramic products. The biggest hole number of it has reached 20~40 per square centimeter, the density is 4~6 grams per cubic centimeter and the water absorption rate is above 20%. The 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%).
Features:
*High strength
*High temperature resistance
*Corrosion resistance
*Wear resistance
*Good thermal conductivity
*Environmentally friendly
Heat exchanger Honeycomb Ceramic Advantages:
*Low heat expansion coefficient
*Llarge surface area, good heat stability and anticorrosion
*High temperature heat accumulation and exchange in industrial waste gas treatment
Heat exchanger Honeycomb Ceramic Applications:
*NOx purification system in the smoke of the thermal power plant
*The harmful gas purification system in rubbish burning
*Poison gas purification system in chemical and mining industries. The slag filter for casting production in the metallurgical industry. The catalyst substrate stuffing material for chemical industry colums and Contact combustion.
