RCM for Boilers

A-criticality units (process-stopping or safety-critical) get the full RCM treatment at asset-by-asset over months with detailed reports per asset. B-criticality units get screening at the same frequency but lighter reporting. C-criticality units get exception-based monitoring — a route check at lower frequency with full diagnostic only when something shifts. The split at most plants is 20% A, 50% B, 30% C of the Boiler Reliability & Maintenance population.

strategy-level, depending on which failure mode is developing. Early-stage signatures on Boiler Reliability & Maintenance appear well before functional failure: rising stack temperature, falling efficiency. Catching the fault early means scheduling the repair into a planned outage — usually 6-16 hours of planned downtime instead of 24-72 hours of unplanned downtime when the asset fails on shift.

Function/failure mode mapping. For Boilers specifically, the signals to watch are rising stack temperature, falling efficiency. A typical RCM report on Boilers reports against the SAE JA1011 and JA1012 framework. Findings tie back to specific failure modes from the Boilers failure population: tube corrosion, refractory degradation, water-side scale.
