Erosion Corrosion

Erosion corrosion is a synergetic effect that accelerates the corrosion attack in the surface of the metal due to the motion of the corrosive fluid. There is an interaction between the solid particles, corrosive fluid, and the material for this corrosion to occur. To better understand this concept, Fig. 6.3 explains how erosion corrosion happens.

Coal

Pulverized-coal-fired boilers emit between 70 and 85 percent of the ash in the coal as fly ash. In contrast, a stoker-fired boiler emits only 3.0 to 50 percent of the coal ash with the flue gas. In addition, the particulate matter generated by stoker boilers tends to be much coarser than the ash from pulverized-coal-fired boilers, and it generally contains considerably more carbon.
