High-alumina heat storage balls for furnace

High-alumina heat storage balls are also called spherical heat storage bodies. Spherical heat storage bodies have the advantages of good thermal shock stability, large heat storage, high strength, easy cleaning, and reusability.

Working principle and characteristics of ceramic heat storage balls

?

1. High-alumina heat storage balls are numerous small balls that divide the air flow into small streams. When the air flow flows through the heat conductor, it forms strong turbulence, which effectively breaks through the boundary layer on the surface of the heat conductor. Because the ball diameter is very small, Small, with small conduction radius, small thermal resistance, high density and good thermal conductivity, it can meet the requirements of frequent and rapid reversal of thermal conductive burners.

2. The heat conductor can use 20 to 30 times/h of reversal. After the high-temperature airflow passes through the heat conductor bed, the flue gas can be reduced to about 130°C and discharged.

3. When high-temperature natural gas and air flow through the heat conductor in the same path, they can be preheated to only about 100°C lower than the flue gas temperature, 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 strong circulation capacity, even if the resistance increases after dust accumulation, the heat exchange index will not be affected.

5. High-alumina heat storage balls have the characteristics of strong resistance to oxidation and slag.

6. The high-alumina heat storage balls are very convenient to replace and clean, and can be reused.
