Stainless Steel Burner Erosion Shield Coal Boiler

Hydrogen sulfide corrosion in low-nox combustion systems | …

Under lowNOx substoichiometric combustion conditions, sulfur in coal is released mostly as H2S gas, which will sulfidize boiler tubes at furnacewall temperatures. The corrosion rates of various alloys and coatings in simulated substoichiometric combustion gas were studied. Carbon steel and Type 304 stainless steel have reasonably good corrosion resistance up to 700 °F (371 °C) and 900 °F

Acid Dewpoint Corrosion - Structural Integrity Materials Services

Introduction Acid dewpoint corrosion can occur in conventional and HRSG units in locations where temperatures fall below the sulfuric acid dewpoint temperature. This can occur when either the boiler tube metal temperatures are below the acid dewpoint so that condensate forms on the metal surface, or when flue gas temperatures are below the acid dew point, so that the condensate will form on
