Thermal storage ball is suitable for the selection of regenerative ball combustion system of gas and non-gas fuel industrial furnaces. It is especially suitable for virtual heating furnace, regenerative ladle roaster, air separation equipment regenerative furnace in air separation industry, regenerative melting furnace in non-ferrous metal industry, and can also be used as a regenerative carrier in large-scale forging plant regenerative car furnace, regenerative electric boiler, regenerative incinerator and other industries. Heat storage balls are divided into solid balls and concave and convex holes.
