Honeycomb ceramic is new developed ceramic part. 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 offer cellular ceramic regeneratorsin more than ten kinds of materials. Due to the unique features of low thermal expansion coefficient, large geometric surface, good thermal stability, and corrosion resistant, they are typically used by refineries, construction plants and chemical processing plants in high temperature heat exchange system and industrial waste gas treatment system.
Applications
Iron, garbage incinerator and waste gas treatment thermal equipment, chemical plants, smelters, industrial boilers, gas turbines, power plants, power engineering and heating equipment, ethylene cracking furnace etc.
Advantages:
*Low thermal expansion coefficient
*High porosity of hole on the wall, good liquidity and uniform distribution
*High temperature resistance, chemical corrosion resistance, thermal shock resistance and thermal shock resistance is strong
*The pressure drop is small
*Cold start performance is good, low light-off temperature, high conversion efficiency
