Design and Function of Plate Heat Exchangers
Operating a plate heat exchanger involves several steps:
Pressure Drop Considerations
Maintaining a specified pressure drop is critical. Excess energy may be necessary if it deviates from the design, signifying potential fouling or clogging. Monitor the flow rate against specifications to uncover discrepancies:
- If the pressure drop exceeds specified values, verify the temperature program.
- If temperature readings are accurate, examine the exchanger for blockages and open the system if necessary.
- If channels constrict and temperature readings differ, CIP (Cleaning in Place) might be required.
