Regenerative Thermal Oxidizer (RTO / RCO) is widely used in the chemical industry, automotive paint, electronics manufacturing, printed circuit board (PCB), toxic gas and electrical manufacturing, wire insulation and mining industries and organic emissions (VOC) purification Chemical Industry tower packing, contact combustion, heat transfer industrial waste gas treatment system. Because of its low thermal expansion coefficient ceramic honeycomb, large surface area, good thermal stability, corrosion resistance and other characteristics to be used as a regenerative heat storage material incinerator, waste gas treatment for my company (RTO, RCO) in different technical requirements, development produce a variety of materials, sizes of cellular ceramic products. Products with a large surface area, small resistance loss, thermal expansion coefficient, high water absorption, good crack resistance and other characteristics, has been widely used in domestic RTO, RCO equipment and tower packing, contact combustion, heat transfer in industrial waste gas treatment system .
