Influence of fouling on plate heat exchanger

Common dirt of plate heat exchanger mainly includes the following:
1: Fragment
2: Aquatic organisms
3: Scale
4: Sediment
5: Scorched substance
Effect of plate replacement scaling:
1: Reduce heat transfer efficiency
2: Increase pressure drop
3; Dirt can damage the plates
4: It causes uneven fluid distribution and uneven cold and heat on the outer surface of the heat exchanger
