Case
Shandong Huaneng Dezhou Power Plant is a 700 MW unit power plant (pulverized coal fired boiler). The water wall tube on the slope of the ash hopper is attacked by loose coking erosion and hard coking impact of the upper furnace, and the wear is the most serious. The laser cladding tube not only has no wear after one year's actual operation, but also does not work properly. The normal operation of the unit has any effect, and can greatly enhance the abrasion resistance and service life of the water wall.
