When designing, put steam on the side of tube so as to prevent high-speed gas passing through the shell side. Also, multiple entries of shell side can be designed to buffer the pressure if the flow of media is relatively high. In addition, an impingement plate should be set to reduce the erosion ...
WebSep 8, 2024 · Corrosion and fouling. How might a heat exchanger flow be restricted or blocked? The process fluids can corrode the surfaces they touch, leading to rust build up or scaling that can reduce the diameter of the tubes and restrict flow. Also, impurities in the process fluid can build up in low-velocity areas of the heat exchanger.
