Factors Influencing Flow Accelerated Corrosion of Air Cooling Condenser

The polarization resistance of air cooling conderser using Q235 steel was measured under different conditions. Various factors affecting the flow accelerated corrosion (FAC) of air cooling condenser were evaluated, and corrosion protection measures were proposed. Results show that FAC rate of the air cooling condenser can be inhibited by increasing the initial condensate pH value and dissolved oxygen concentration, and reducing the operation temperature.
