Power Plant Chemistry

DESCRIPTION

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

The course provides and 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 in proper boiler water chemistry. The results of a multi-million dollar overhaul can be negated during start-up due to in proper boiler water chemistry.

OBJECTIVE

1. Describe the theory behind chemical analysis and control used in the power plant.
2. Discuss the safety requirement to be followed during sampling, analysis, and addition of chemical.
3. Describe the procedures for sampling and analyzing various water sources.
4. Describe the basis for the various chemistry limits imposed for different system in the power plant.
5. Describe the mechanism for the various types of corrosion and how this corrosion is controlled.
