Heat Storage Ceramic Ball Description
Heat Storage Ceramic Ball has features of high strength, low abrasion loss, large heat capacity, and thermal conductivity resulting in efficient heat storage performance, excellent resistance to high temperature, and thermal shock. It is widely used in recuperators in the air separation process and also used to pre-heat the gas and the air in coal gas heating furnaces in iron & steel plants.
