Product Description

Baffle bricks, also known as fire bricks or block bricks, are generally installed behind the burner of a regenerative heating furnace.Used to support and add medical ceramic thermal storage materials, it can be used in various thermal storage combustion systems in conjunction with honeycomb bodies. It is used at the forefront of the thermal storage body in a thermal storage heating furnace to protect the thermal storage.

The baffle brick can be used in conjunction with the honeycomb body in the central regenerative combustion system. It is used at the front end of the regenerative body in the regenerative heating furnace to protect the regenerative body and extend its service life. Therefore, high temperature resistance and thermal shock resistance are important factors in selecting baffle bricks.
