The working principle and characteristics of high alumina heat storage ball

The high-alumina heat storage ball is also called the spherical heat storage body. The spherical heat storage body has the advantages of good thermal shock stability, large heat storage, high strength, easy cleaning, and reusability.

The working principle and characteristics of high alumina heat storage ball

 1. The high-alumina heat storage ball is a large number of small balls that divide the airflow into small streams. When the airflow flows through the heat conductor, it forms a strong turbulent flow, which effectively breaks through the surface layer of the heat conductor. Small, small conduction radius, small thermal resistance, high density, and good thermal conductivity, so it can meet the requirements of frequent and fast reversing of the thermally conductive burner.

2. The heat conductor can use the reversal of 20~30 times/h. After the high temperature flue gas flows through the heat conductor bed, the flue gas can be reduced to about 130℃ and discharged.

3. The high-temperature gas and air can be preheated to only about 100℃ lower than the flue gas temperature by flowing through the heat conductor in the same path, and the temperature efficiency is as high as 90%.

4. Because the volume of the heat conductor is very small, and the high-alumina heat storage pebble bed has a strong flow capacity, even if the resistance increases after dust accumulation, the heat exchange index will not be affected.

5. The high-alumina heat storage ball has the characteristics of strong oxidation resistance and slag resistance.

6. The replacement and cleaning of the high-alumina heat storage ball are very convenient and can be reused.

Main specifications of high alumina heat storage ball: Φ3, 6, 8, 10, 13, 16, 19, 25mm.

High alumina heat storage ball alumina content: 92% 95% 99%.

High-alumina heat storage ball packaging: 25kg net weight of pp bag,  pallet.

Advantages of ZAWA products: high strength, abrasion resistance, resistance to rapid cold and heat, long use time.

Application of high-alumina regenerative ball: widely used in industrial furnaces such as steel and metallurgical industry heating furnaces, aluminum melting furnaces, forging furnaces, etc. It is especially suitable for the regenerators of air separation equipment and blast furnace gas heating furnaces in steel plants as heat storage fillers. Through double preheating of gas and air, the combustion temperature can quickly reach the requirements of steel rolling for heating billets.
