Working principle and characteristics of high aluminum heat storage ball

1. High-aluminum heat storage balls are many small balls that divide the airflow into very small streams. When the airflow flows through the heat conductor, it forms a strong turbulence, effectively breaking through the boundary layer on the surface of the heat conductor. Because the ball diameter is very small, the conduction radius is small, the thermal resistance is small, the density is high, and the thermal conductivity is good, the requirements of frequent and rapid reversal of the heat conduction burner can be met.
2. The heat conductor can be used for 20~30 times/h reversal. After the high-temperature flue gas flows through the heat conductor bed, the flue gas can be reduced to about 130℃ for discharge.
3. High-temperature coal gas and air can be preheated to only about 100℃ lower than the flue gas temperature in the same path through the heat conductor, and the temperature efficiency is as high as more than 90%.
4. Because the heat conductor is very small in size and the high-aluminum heat storage ball bed has a strong flow capacity, even if the resistance increases after ash accumulation, it does not affect the heat exchange index.
5. High-aluminum heat storage balls have strong anti-oxidation and slag resistance.
6. The high-aluminum heat storage ball is very easy to replace and clean and can be reused.

Refractory heat storage balls are used for:

Refractory heat storage balls are widely used in heating furnaces, aluminum melting furnaces, forging furnaces, and other industrial furnaces in the steel and metallurgical industries. They are particularly suitable for use as heat storage fillers in air separation equipment regenerators and steel plant blast furnace gas heating furnaces. By preheating both gas and air, the combustion temperature can quickly reach the requirements for heating steel billets in steel rolling.
