Product Descriptions

Regenerative ceramic ball is also a kind of inert ceramic ball. It is mainly used in high-efficiency regenerative blast furnace gas heating furnace. It acts as regenerative adsorption and heat exchange in regenerative chamber heat exchanger of preheating section, and maintains high heat capacity switching at high temperature of reaction.

Main Specifications of Regenerative Porcelain Balls: Φ16mm Φ18mm Φ20mm Φ25mm Φ30mm Φ50mm

The main shapes are ceramic ball, porous cylindrical ceramic ball and porous circular ceramic ball.
