Reduce Hydrogen Damage. Reduce Boiler Tube Failures. Improve Unit Reliability. Minimize Corrosion Deposition. Learn the proper response when chemical parameters are exceeded. Understand the consequences of operation while boiler and feed water chemistry limits are being exceeded.

This Seminar is designed for fossil power plant operators and supervisors who are involved in testing feed water and boiler water and making adjustments to chemical pumps based on their analysis. The Seminar provides an understanding of the role of chemistry in a power plant and the effect of chemical controls on the operation of the system.

Unit efficiency, reliability, and availability can be adversely affected by improper boiler water chemistry. The results of a multi-million dollar overhaul can be negated during start-up due to improper boiler water chemistry. HPC instructors bring over 30 years of hands on experience to this training Seminar.

OBJECTIVES
Upon successful completion of this Seminar the participant should be able to:
  1. Describe the various types of impurities found in water.
  2. Describe the differences between elements, compounds, and mixtures.
  3. Describe the Octet rule and valence shells.
  4. Describe the difference between a solvent and a solute.
  5. Describe the difference between acids and bases.
  6. Describe the factors that effect corrosion.
  7. Describe the methods to reduce or prevent corrosion.
  8. Describe the various means of raw water treatment.
  9. Describe the phase changes of water.
  10. Describe the types and purposes of various types of feedwater and boilerwater chemical treatment.
  11. Describe the various types of in-line analyzers.
