     The air speed in the tertiary air duct increases from *0m/s to over *0m/s. Due to the increased thermal-efficiency of coolers, the temperature of the tertiary air has been increased to over **0℃. The clinker dust under high temperature and high air speed deepens the abrasion of lining, which requires good abrasion-resistance for the lining in corners and valves.
     According to operating condition, own technics and product advantages, our group suggests to apply the silicon mullite compound bricks in the tertiary air duct, which can increase the abrasion-resistance, decrease the thermal-dissipation, and remarkably conserve energy and protect environment with ceramic tertiary air flashboards.
