“…For 1018 steel elbows, the synergies between erosion and corrosion reached 56% at a flow rate of 2.5 m•s −1 , and they decreased to 11% at a flow rate of 4.0 m•s −1 . Elemuren et al 30 also carried out similar erosion−corrosion experiments on 2205 stainless steel. The results showed that the mass loss of 2205 was mainly caused by mechanical erosion, and the plastic deformation caused by the repeated impact of particles carried in liquid on the material surfaces was the main reason for the material stripping.…”

The recovery of low-grade waste heat from power plants greatly benefits energy conservation and emission reduction during electricity generation, while the waste heat utilization directly from desulfurization slurry is a significantly promising method to deeply recover such low-grade energy and has been developed in practical application. However, the pipe materials are subjected to erosion and corrosion challenges due to the high level of solid compositions and the presence of harmful ions, such as Cl −1 , which requires further evaluation under the condition of slurry heat exchange. The present study aimed at an experimental study on the erosion−corrosion characteristics of desulfurization slurry on three types of stainless steel, including type 304, 316L, and 2205. Both mass loss and micromorphology features were analyzed with possible mechanisms elucidated. The erosion−corrosion rate is weak at low temperatures, while the increase in the slurry temperature clearly promotes its rate. The influence of the temperature on the corrosion resistance of 304 is much greater than that of 2205. With an increase in duration time, the weight loss rate of stainless steel in the desulfurization slurry declines, and the changing trend of metal mass slightly slows down. The present study offers a better understanding of the erosion−corrosion behaviors of three types of stainless steel under flow and heat transfer conditions of a desulfurization slurry.
