waste heat boilers often suffer from:
These processes are caused by the presence of a combination of sulfur, halides and water vapor within a high-temperature environment.
The flue gas stream within a Smelting Furnace WHB has a high dust content. It may either slag on the surface, depending on its melting point temperature, or erode waterwall, as it mainly consists of a variety of metal oxides.
Dew Point corrosion in metal-air preheaters leads to rapid corrosion and breakdown of plates and tubes. This results in decreased energy efficiency and performance of WHBs.
To avoid asset failure, preventative action should be taken to ensure efficiency and prevent costly unplanned shutdowns.
