Reduce hydrogen damage, reduce boiler tube failure, and improve unit reliability. Minimize corrosion deposition. Learn the proper response when chemical limits are exceeded. Understand the consequences of operation while boiler and feed water chemistry limits are being exceeded, proper laboratory QA/QC water (and fuel) testing methods, and how to calculate safe contaminant levels in boiler and feedwater.

This Seminar is designed for fossil power plant laboratory technicians and supervisors. The Seminar provides an understanding of the role of chemistry in a power plant, the effects of chemical excursions, and how to determine chemical limits. It also provides a discussion of testing methods, the need for a quality assurance/quality control program, and how to set up a QA/QC program. Coal and oil sampling and analysis can be provided on request.

OBJECTIVES
Upon successful completion of the Seminar, the participant should be able to:
  1. Describe various chemical treatment programs
  2. Determine chemical limits for a unit.
  3. Respond properly to chemical excursions
  4. Describe proper sampling and analysis methods
  5. Discuss the components of a QA/QC program
  6. Describe the mechanisms for various types of corrosion and how this corrosion is controlled.
