Detail Description

1. Product Description

Heat Storage Ceramic Ball is characterized by its high strength,low abrasion loss,large heat capacity and thermal conductivity result in efficient heat storage performance,excellent resistance to hight temperature and the thermal shock.The balls have been effectively used in recuperator in air separation process and also used to pre-heat the gas and the air in coal gas heating furnace in iron&steel plant.

In order to improve the heater’s storage and release effectiveness and prolong the using life. We developed roughness groove-opening hole high effective heat storage ceramic ball and applied patent.
This kind of heat storage ceramic ball open the hole as diameter for axes and set up groove at the surface, making the ball surface convavo-convex, for which the specific area and void volume can be increased, and its exchange area is doubled 1.8 than normal thermal storage ceramic ball. It will enhance the precuts spalling resistance ability and the bulk density will be decreased by 15%.The materials distribution and flux will be further increased, while system’s resistance is reduced, block of the powder also get reduced.
