Common failures & inspection points
Visual examination of heat exchanger tubes, double coil bare tube configuration, and combustion chamber for scale deposits, corrosion, and erosion. Access plates and manholes must be removed for thorough inspection.
Verification of thermal fluid properties (viscosity index >100, flash point COC >180°C, film temperature capability ≥340°C) and check for oxidation/degradation indicating fluid change requirement
Testing of safety valves (main system valve at 10 bar(g), expansion tank valve at 4 bar(g), minimum flow control at 2.5 bar(g)) and documentation of pressure test results per ASME/PED standards
Examination of refractory lining for cracks, spalling, or deterioration; inspection of external insulation jacket for damage; thermal camera inspection for heat loss anomalies
Inspection of burner assembly (monoblock pressure jet or rotary cup), flue gas analysis, combustion chamber temperature verification, and soot accumulation assessment. For EX models, soot-cleaning nozzle functionality check
