Heat storage ball

What are heat storage balls made of?

We design and manufacture heat storage balls (diameter: 11mm to 22mm) made of materials such as high alumina, corundum mullite, chrome corundum mullite and zirconia corundum mullite. This brings the advantages of high slag resistance, quick heat transfer, heavy volume weight and large storage capacity.

Can a core–shell ball store latent heat?

It was confirmed that the core–shell ball can store latent heat and is superior to the conventional solid alumina ball in terms of heat storage rate and heat storage density.

Which alloy capsule is more advantageous in high-temperature rapid heat storage?

This shows that compared with alumina ball, the Al–12.2%Si alloy capsule is more advantageous in high-temperature rapid heat storage because of its excellent thermal diffusivity at high temperatures. The heat storage and release cycle of regenerative burner is generally 30 s–60 s.

What is the convection coefficient of alumina ball and alloy capsule?

Under the heat transfer boundary condition with convection coefficient of 100 (W/m･K), alumina ball and alloy capsule with initial temperature of 25 °C exchange heat with air of 1200 °C for one minute and their the temperature distributions are shown in Fig. 8 A,B.
