Understanding of Fireside Corrosion - David N. French

2017-10-17 · The corrosion rate is especially high in coal-fired units when the tubes are operating between 1100 and 1250oF. In this temperature range, complex liquid sulfates (Na 3 Fe(SO 4) 3 or K 3 Fe(SO 4) 3) form, resulting in rapid corrosion. Figure 2 illustrates the view of coal ash corrosion that had occurred on the tube OD. Figure 3 illustrates the
