Further Understanding of Furnace Wall Corrosion in …

2017-3-6 · The contribution of active sulfidation to furnace wall corrosion is likely proportional to the chlorine content in coal. When the Cr concentration in the alloy is sufficiently increased, a more protective scale can be formed on the surface upon exposure to the reducing and sulfidizing low-NO x environments from staged combustion. As a result
