Large Supply Ceramic Honeycomb Heat Exchanger
Product Description
Honeycomb ceramic heat accumulation substrate heat capacity can be achieve at 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. So It has got a wide application in many industrial productions. 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. The 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. We can make honeycomb ceramic various material. Like alumina, multiple cordierite etc.
High Temperature Air Combustion (HTAC) is a revolutionary combustion system, which achieves the outstanding fuel saving by high preheated air combustion and high efficiency waste heat recovery. Honeycomb ceramic with more characteristics such as high surface area, high heat transfer ability, strong thermal shock resistance, high operating temperature, anti-iron oxide skin erosion, effective in reducing the size and weight of regenerative boxes. It can achieve low NOx emission more than 40%.
Heat exchanger Honeycomb Ceramic Advantages:
*Low heat expansion coefficient
*Large 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.
