1. Heat Transfer Efficiency: Calculate and assess the heat transfer efficiency of the heat exchanger by comparing the actual performance with design specifications. Deviations may indicate fouling, scaling, or other issues affecting efficiency.
  2. Pressure Drop Analysis: Evaluate pressure drop across the heat exchanger to ensure it falls within acceptable limits. Excessive pressure drops can indicate fouling or blockages that impede fluid flow.
  3. Temperature Profiles: Examine temperature profiles at various points within the heat exchanger to identify uneven heat distribution, which may be indicative of fouling or inadequate flow patterns.
  4. Thermal Performance Monitoring: Implement continuous thermal performance monitoring, incorporating sensors and instrumentation to provide real-time data for prompt identification of deviations from expected performance.
