Thermal Store Honeycomb Ceramic

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℃, 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 160℃. It will reduce the greenhouse effects of the earth greatly. If the HTAC technology is adopted by most industry stove kilns of the whole country, its economic benefits and social benefit are inestimable. It will alleviate the state of the energy in short supply greatly and improve the human living environment effectively.
The thermal store has mainly following three kinds: honeycomb ceramic, heat-storage ball and heat-storage pipe. The specific surface area of honeycomb ceramic is more than 5 times of the heat-storage ball and more 4-5 times of heat-transfer capacity, airflow resistance only 1/3 of the heat-storage ball, and small depth of heat penetration. Honeycomb ceramic is in favor of hypoxia combustion than heat-storage ball, make furnace temperature uniformity, conduct heat fast, and tap steel fast. It reduces oxidation, scale losses and NOx gassing greatly; improve the energy-conserving and environmental protection notably. The volume of regenerator is reduced by adopting honeycomb ceramic. The burning mouth can be assigned enough quantity for meeting needs of thermal load. And the straight gas stream pass-way of honeycomb ceramic is more difficult to jam than labyrinth pass-way of the heat-storage ball, since it is perfect self-cleaning and suitable for our country's non-clean combustion characteristic.
The cordierite and alundum mullite thermal store honeycomb ceramic of our company develops recently has the following notable characters: perfect high-temperature resistance, anticorrosion, perfect thermal shock stability, high mechanical strength, large thermal storage capacity, advantaging heat- conduction property, energy-conserving result and service life are improved greatly. Our products have already been approved by numerous iron and steel enterprises domesticly at present and exported to Japan, S. Korea and American-European market.
