New TIP proposed on inspection design for black liquor recovery boilers

Print Print this article | Send to Colleague

A new TIP has been proposed: Inspection design for black liquor recovery boilers: a re-examination of the conventional wisdom about inspection methods and frequencies

The abstract is as follows: Condition awareness is a crucial factor in the maintenance and repair decisions made during the life of any boiler.  Black liquor recovery boilers have unique hazards and inspection requirements.  Thorough, thoughtfully directed, and efficiently applied condition monitoring efforts are most likely to result in effective and timely maintenance activity that will increase reliability and maximize the life of the boiler.  Experience and research have advanced sufficiently that the industry needs to re-examine the scope and frequency of destructive and non-destructive inspection and testing in black liquor recovery boilers.

The purpose of this technical information paper (TIP) is to offer a modern approach to recovery boiler inspection that includes: preparation of the boiler for inspection; identification of the failure mechanisms common to recovery boilers; the locations where these mechanisms occur; and the technologies, both destructive and nondestructive, that can assure the accumulation of accurate information about the condition of the boiler.  Reference is made to numerous existing TIPs that offer specific techniques for nondestructive examination that will not be repeated in this document.

If you would like to participate in the review of this new TIP, please send a message to no later than February 23, 2015.
