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.
