CleanSwitch
Executive summary
External walkdown of the CleanSwitch RTO found no abnormalities on the housing, ductwork, gas train, dampers, or access structures. Nameplate data was captured for two units (CS-650 shipped 03/2016 and CS600 shipped 09/2010), and safeties tested OK during the electrical and pneumatic check. Given the 14+ year service age on the older unit, schedule an internal media bed and switching valve inspection at the next planned outage.
Prioritized actions
- 1 INFOPlan internal media bed and switching valve inspection at next scheduled outage on CS1123.
- 2 INFOArchive captured nameplate data (CS1217 and CS1123) in equipment master record for traceability.
- 3 INFOVerify exhaust fan vibration and bearing temperature trends against baseline at next PM.
- 4 GOODContinue routine external walkdowns of ductwork, gas train, and damper actuators.
Findings
Findings
1234Exterior of the CS300 housing, insulated process inlet duct, yellow natural gas train, and yellow access ladder/platform all present as installed with no visible deformation, coating failure, or leakage. Control enclosure with side-mount cooling unit is intact.
No action. Maintain on standard external walkdown cadence.
123Front-side view of the isolation/fresh air damper actuator, tee damper junction, and exhaust fan housing shows sound seams and no actuator leakage or housing deformation. Galvanized ductwork is in serviceable condition.
Trend exhaust fan vibration and damper stroke times at the next PM to confirm continued health.
123B&W MEGTEC nameplate is legible: Unit CS1217, Model CS-650, shipped 03/2016. Unit and project numbers recorded for the equipment file.
Log nameplate data in the asset register and link to this walkdown record.
123Job tag confirms Model CS600, Project 10015699, ship date 09/2010, handwritten unit ID CS1123 — approximately 14 years in service. Electrical and pneumatic safeties tested OK at the time of walkdown.
Given service age, schedule an internal inspection of media beds, poppet shafts, and switching valve seats at the next planned outage.
1234Internal-inspection-day overview shows the main process inlet duct connection, natural gas header to the burner, Media A access hatch, and service platform/ladder all in sound condition with no visible leaks or structural concerns.
Proceed with planned internal media bed inspection; no external corrective action required.
