This TIP describes a process for planning a recovery boiler inspection by specifying an inspection scope for each boiler zone to find possible damage mechanisms in their most likely locations, using the most efficient inspection and non-destructive testing (NDT) methods to quantify and trend the damage. Using the practices described in this TIP, a recovery boiler owner/operator can rationally allocate the correct amounts of time, scaffolding and inspection/NDT resources to learn everything necessary to improve the boiler’s reliability at lowest cost.

Built on inspection design practices in regular use in the nuclear, refining and chemical industries, the inspection planning process described in this TIP can ensure that an inspected recovery boiler returns to service with the owner having an understanding of the extent and rate of damage mechanisms affecting each part of the boiler. This method of designing the inspection scope applies equally well to power boilers and other fixed equipment.

Appendix A has a comprehensive list of damage mechanisms and corresponding recommended inspection methods. Nothing in this document is intended to replace or supersede jurisdictional requirements.
