honeycomb ceramic heat transfer media for RTO-low heat expansion ratio,high thermal shock resistance,large specific surface area

Heat Transfer Media for RTO is the patented product in our company.

Honeycomb ceramics 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

It is a new-type combustion Tec with enormous energy-conservation and environmental protection that High Temperature Air Combustion (HTAC). The thermal store honeycomb ceramic is used extensively in the various field, such as the steel, machinery, building materials, petrochemical industry, colored metal etc, as the key part of HRC, such as different kinds of heating furnaces, hot-blast furnace, heat-treatment furnace, cracked stove, roaster, melting furnace, hot stove, oil gas boiler, etc. This technology is to make two regenerator to absorb heat and send out heat alternatively through the direction change device, recuperate the heat of the exhaust gas to the maximum extent, and then heat the combustion-supporting air and coal gas to more than 1000 Celsius degrees, even the inferior fuel (e.g. the blast furnace gas ) of lower calorific power can also catch fire steadily and burns high-efficiently. It can save 40-70% of fuel, improves output more than 15%, decreased more than 40% that billet steel is oxidized and burnt, NOx tap smaller than 100ppm, and make the temperature of exhaust gas emission lower than 160Celsius degrees. It will reduce the greenhouse effects of the earth greatly.

Main material:Al2O3, Cordierite,Alundum mullite, Zr-Cr corundum.
