The high alumina heat storage ball is also called a spherical heat storage body, and the spherical heat storage body has the advantages of good thermal shock stability, large heat storage capacity, high strength, easy cleaning, and reusability.
Working principle and characteristics of high alumina heat storage ball
1. High alumina heat storage ball is a small ball that divides the airflow into small streams. When the airflow flows through the heat conductor, it forms a strong turbulent flow, effectively breaks the surface layer of the heat conductor surface, and because the ball diameter is very small, small conduction radius, small thermal resistance, high density, good thermal conductivity, so the requirements of frequent and rapid commutation of the heat-conductive burner can be realized.
2. The heat conductor can be reversed by 20~30 times/h. After the high-temperature smoke flow passes through the bed of the heat conductor, the flue gas can be reduced to about 130 °C.
3. The high temperature gas and air flowing through the heat conductor can be preheated to the same temperature only about 100 ° C lower than the flue gas temperature, and the temperature efficiency is as high as 90% or more.
4. Due to the compact size of the thermal conductor, coupled with the high circulation capacity of the high aluminum heat storage ball bed, even if the resistance increases after the accumulation of ash does not affect the heat exchange index.
5. High alumina heat storage ball has the characteristics of strong oxidation resistance and slag resistance.
6. High alumina heat storage ball replacement and cleaning is very convenient and can be reused.
High alumina heat storage ball use: widely used in steel, metallurgical industry heating furnace, alumina melting furnace, forging furnace and other industrial furnaces. It is especially suitable for air storage equipment regenerators and steel furnace blast furnace gas heating furnaces as heat storage fillers. By double preheating the gas and air, the combustion temperature can quickly reach the requirements of steel slab heating.
