(1) Grinding system

The wear and tear of the pulverized coal system in coal-fired power plants mainly comes from the collision, friction and impact of pulverized coal. The high-speed air flow of pulverized coal causes serious wear and tear to the equipment of the pulverized coal system, especially the outlet pipe of the coal mill, the elbow of the primary air duct, and the inlet and outlet pipes of the coarse powder separator and the fine powder separator. The application of alumina ceramic liner or ZTA ceramic liner 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 removal and slag removal systems, inlet and outlet pipe sections such as ash pumps and ash ditch nozzles are most susceptible to wear. Depending on the working conditions on site, it is more suitable for attaching adhesive ceramics. Maintenance personnel no longer frequently plug leaks and replace equipment, and the sanitation of the site has improved considerably.

(3) Coal conveying system

The wear and tear of coal conveying system equipment mainly comes from impact, and the most easily worn parts are coal falling pipes, tees, baffles, etc. The application of ZTA zirconia aluminum composite ceramic liner is an ideal treatment method
