Understanding Steam Path Audits: Efficiency Audits & Structural Audits Webinar

Speaker: Deborah Cioffi, Engineer Consultant & Jeff Newton, Steampath Engineer

This presentation will discuss the process and benefits of an efficiency steam path audit, how to use the results during the outage to maximize thermal performance and minimize maintenance costs. 

The Structural Steampath Audit portion will describe the evaluation of the condition of rotating and stationary steampath components including the effects of foreign object damage, solid particle erosion, moisture erosion, and rubbing. Bucket covers and notches are checked for lifting. Recommendations for repair or replacement are provided based on reliability.

Key Takeaways:

1. A list of recommended maintenance with the corresponding improvement in power output, heat rate, and efficiency quantified on a stage-by-stage basis.
2. Root cause of the damage so a long-term solution can sustain high-performance levels.
3. Structural steampath audits should be done early in an outage (preferably as soon as the blasting and NDE are done) to allow the maximum time for repair or replacement of steampath components during the outage schedule.
4. The audits identify reliability issues with steampath components and provide recommendations for replacement or repair often with multiple options.
