Understanding the role of S and Cl degrading the corrosion resistance of 12Cr1MoVG steel in a waste incineration boiler: on-site and laboratory testing

Year: 2024

Type: article

Abstract: The corrosion behavior of 12Cr1MoVG tube in a waste incineration boiler superheater was investigated using on-site and laboratory testing. Low-melting-point ZnCl 2 and PbCl 2 induced the formation of eutectic mixtures. These eutectic mixtures captured ash particles, resulting in severe slagging on the 12Cr1MoVG tube. The structure of the oxide layer on the 12Cr1MoVG tube was severely disrupted by the high S and Cl contents in waste fuel. Under the influence of brittle Fe 2 O 3 and FeS spalling, FeCl 2 dissolution, FeCl 3 and FeSO 4 volatilization, and severe internal oxidation, corrosion perforation appeared in the 12Cr1MoVG tube.
