1) Grinding system

The wear of the coal powder system in coal-fired power plants mainly comes from the collision, friction, and impact of coal powder. The high-speed airflow of coal powder causes serious wear and tear on the equipment of the coal powder system, especially the outlet pipes of the coal mill, the elbows of the primary air pipes, the inlet and outlet pipes of the coarse powder separator and the fine powder separator. The application of alumina ceramic lining plate or ZTA ceramic lining plate has achieved good results and has been recognized by users. Its biggest advantage is its simple structure and low cost.

(2) Ash system

For power plants that use hydraulic ash and slag removal systems, inlet and outlet pipe sections such as ash pumps and ash ditch nozzles are most prone to wear and tear. According to the working conditions on site, it is more suitable to stick adhesive type ceramics. The maintenance personnel no longer frequently seal leaks and replace equipment, and the on-site hygiene has greatly improved.

(3) Coal conveying system

The wear of coal conveying system equipment mainly comes from impact, and the most easily worn parts are coal chute, tee, baffle, etc. The application of ZTA zirconia aluminum composite ceramic lining plate is a relatively ideal treatment method
