Waste Heat Boilers (WHB) generate steam while cooling a process fluid. Depending on process and steam system considerations, varied boiler designs and pressures are utilized. Some designs are susceptible to waterside corrosion problems and tube failures may be prevalent. Examples are used to illustrate various failure mechanisms involving different WHB designs.
