Operation and maintenance guidelines for draft fans
- Sargent and Lundy, Chicago, IL (United States)
Large draft fans typically account for more than one-fourth of a generating unit's auxiliary output. Industry data indicates that failure of draft fans is among the top 15 causes of outages. These guidelines offer comprehensive coverage of major topics, such as fan operation, maintenance, troubleshooting, wheel inspection, and weld repairs. Each section provides extensive road maps describing step-by-step procedures for implementing mutually supportive operating and maintenance strategies. The guidelines emphasize preventive maintenance through checks and predictive maintenance through vibration and temperature monitoring. Moreover, the guidelines present a tri-level maintenance structure of prestart checks, operational checks, and out-of-service checks. Utilities may use the guidelines in developing and refining overall operation and maintenance procedures for large draft fans in power plant applications.
