Heat storage ceramic ball and thermal storage alumina beads for accumulator
Heat storage ceramic ball have been effectively used in regenerator in air separation process, and also used to pre-heat the gas and the air in coal gas heating furnace in iron & steel plant.
Specification Of Heat Storage Ceramic Balls
Heat storage ceramic balls are specialized ceramic media designed for thermal energy storage and heat exchange in high-temperature industrial processes. Made from materials such as alumina (Al₂O₃), mullite (3Al₂O₃·2SiO₂), or silicon carbide (SiC), these balls are widely used in applications like regenerative thermal oxidizers (RTOs), heat recovery systems, and industrial furnaces. Their high thermal stability, durability, and ability to store and release heat efficiently make them ideal for energy-saving and pollution control systems.
Key Features of Heat Storage Ceramic Balls
High Thermal Stability:
Can withstand extreme temperatures (up to 1600°C or higher), making them suitable for high-temperature applications.
Excellent Heat Storage Capacity:
Efficiently stores and releases thermal energy, improving energy efficiency in industrial processes.
Chemical Resistance:
Resistant to corrosion and chemical attack from acids, alkalis, and organic solvents.
Low Thermal Expansion:
Minimal expansion under high temperatures reduces the risk of cracking or damage.
Mechanical Strength:
Durable and resistant to breakage, even under high-pressure conditions.
Uniform Size and Shape:
Precise dimensions ensure consistent performance and optimal heat transfer.
Main specifications: Φ16mm, Φ18mm, Φ20mm, Φ25mm.
Material: High aluminum and corundum mullite.
