Induced draft fans extract coal-fired boiler exhaust gases in the form of a two-phase flow with a dispersed solid phase made of unburnt coal and fly ash consequently fan blades are subject to erosion causing material wear at the leading edge, trailing edge, and blade surface.

2019-4-17Corrosion due to fly ash is one of the gas-side problems troubling coal-fired boilers. Solid or liquid particles in the gas flow collide with the HTS and or structural members and erode or injure those surfaces mechanically. Quantitative estimation of erosion is not easy since it is difficult to clarify the mechanism of erosion.

This paper presents a computational analysis of fly ash erosion on superheater tubes of a coal furnace. The investigation was held based on a hypothesis that erosion by coal ash particles have caused an untimely fail- ure of a superheater tube during the initial running of a relatively new coal fired power plant.

Coal generation fell by a massive 22 in 2015-16, and the Trump administration has not been able to reverse this even though the rate of decline has slowed. The continued stream of closures and retirement announcements point to further erosion of US coal-fired capacity with extremely little in terms of new build capacity proposed.

500 o-750 o F. Waterwall-tube corrosion occurs in coal-fired units by the formation of pyrosulfates of sodium and potassium. In refuse-fired boilers, mixtures of chlorides of zinc, lead, iron and sodium are the likely causes of corrosion. Temperatures greater than 1000 o F. The cause of superheater and reheater ash corrosion depends on the fuel.
