Coal ash corrosion generally occurs as the result of the formation of low melting point, liquid phase, alkali-iron trisulfates. During coal combustion, minerals in the coal are exposed to high temperatures, causing release of volatile alkali compounds and sulfur oxides.

 · The seven major locations in which boiler erosion occurs are at the fire side,the preboiler, the afterboiler, and the water side and steam side. Fire-side mechanisms cause most erosion-related failures and can be further subdivided as erosion related to soot blowing, steam cutting, flyash attack, coal-particle impingement, and falling slag.

One of the most severe types of high-temperature corrosion is ash deposit corrosion. This ash deposit corrosion can be divided as coal ash deposit corrosion and oil ash deposit corrosion depending on the fuel used for the boilers. Both types of ash deposit corrosion are due to fluxing action of the salt deposit , .

Mils per year or MPY is used to give the corrosion rate in a pipe, a pipe system or other metallic surfaces. It is used to calculate the material loss or weight loss of a metal surfaces. There is a formula using the type of metal, the size of the sample area and the time of exposure, giving the value of mils per year. Convert 1 mil to mm

Coal Mill Classifier Repair PROBLEM. The Coal Mill Classifier Cone directs the pulverized coal out of the mill and into the furnace. Hot air, from the air side of the air preheater, is pulled through the coal mill by the exhaust fan (refer CH-801) picking up the fine coal dust and feeding it to the furnace.
