In this Seminar we will climb inside the boiler (not literally) to better understand the how's and why's of boiler operation and maintenance. Understanding of the results of O&M decisions can improve boiler efficiency and reliability: two important variables needed to compete in today's marketplace. Proper boiler operating decisions are imperative to an efficient operating plant. Proper boiler maintenance decisions are imperative to an efficient and reliable operating plant. In this 4-day Boiler O&M class you will learn to make informed O&M decisions. Learn the benefits of various corrective actions that may be taken to repair a boiler and associated equipment. Learn more regarding O&M of the various components supporting boiler operation. Learn why a component is failing or has failed. Proper maintenance and operation can increase availability and reliability.

This 4-day Seminar is designed for all maintenance and operations personnel involved in the daily use of steam boilers.

  3. Describe the various factors that determine proper combustion in the steam generator.
  4. List the major components of a steam generator.
  5. Describe the relationship of the major components of a steam generator.
  6. Describe practical burner design with specific attention given to low NOx burners.
  7. Describe the fundamental means for conducting efficiency testing on a steam generator.
  8. List and describe a minimum of three ways one can improve steam generator efficiency.
  9. Provide a basic description of the basic boiler metallurgy.
  10. Given a fan characteristic curve, describe its use.
  11. Describe the areas involved in a utility boiler inspection.
  12. Given specific failure modes of a fossil-power plant boiler, describe the cause, how this failure might be prevented and routine repair procedures that might be applied.
  13. Describe the most typical failure modes for boiler tubes.
  14. Describe typical repair modes of failed boiler tubes.
  15. Describe the major components of centrifugal pumps.
