Ceramic honeycomb is one kind of industrial porous ceramics, many passable parallel channels are ramified over its inside. Each individual part made up of these honeycomb ceramics are constructed into the shape with square cells at two ends. Compared with ordinary ceramic materials, they are characterized by low heat expansion ratio, high thermal shock resistance, large specific surface area, anticorrosion etc .

Ceramic honeycomb regenerator is the key and core component on high temperature air combustion technology. It has large specific area, specific heat, low coefficient of thermal expansion.
