The regenerative ceramic ball is made of AL2O3, kaolin, synthetic aggregate and mullite crystal. According to rolling and press forming, two kinds. The product has the advantages of high temperature resistance, high corrosion resistance, high density, low thermal resistance, high thermal resistance, good thermal conductivity, high thermal conductivity and heat capacity, high thermal capacity, high thermal capacity, high thermal stability and not easy to break when the temperature is changed. The specific surface area can reach 240m2/m3. In use, many small balls divide the air into very small stream, and the flow of air flows through the regenerator, forming a strong turbulence, which effectively breaks the surface layer of the heat storage body, and has small radius, small heat resistance, high density and good thermal conductivity because of the small diameter of the ball. So the frequent and fast change of the regenerative burner can be realized. Please.
The technology is through the double preheating of gas and air, even low heat value of the inferior fuel can also achieve stable ignition, so that the burning temperature can quickly meet the requirements of steel rolling for the steel billet. At the same time, it is convenient to replace and clean, and can be reused and has long service life. The regenerator can use the direction of 20~30 times /h. After the high temperature flue gas flows through the regenerator bed, the flue gas can be discharged to about 130 degrees Celsius. High temperature gas and air flow through the regenerator can be pre heated in the same path to 100 degrees Celsius only than the flue gas temperature, and the temperature efficiency is as high as 90%.
Because the volume of the heat storage body is very small and the flow capacity of the pellet bed is strong, even if the resistance increases after ash accumulation, it will not affect the heat transfer index.
Application areas:
The regenerative porcelain ball is especially suitable for the regenerator of the air separator and the blast furnace of the iron and steel plant. Through double preheating of the air and air, the burning temperature can quickly meet the requirements of the steel rolling for the steel billet.
Main specifications: 16mm, 18mm, 20mm and 25mm
Classification: according to product material, it is divided into high alumina and corundum mullite. The shape is mainly composed of three kinds: ceramic balls, porous cylindrical porcelain balls and porous round ceramic balls.
