CHEMICAL IN POWER PLANT
Course
Overview
Power plants are inherently very complex systems. The challenge for
power plant operators is to ensure maximum safety in all the processes of the
water cycle. All components, including the piping systems, must conform to the
highest safety and reliability standards. The piping systems in power plants,
in particular, are exposed to excessive loads when transporting the acids and
alkalis required for water treatment. Presented in the following are several
processes in which aggressive chemicals are used and which can cause corrosive
damage in pipe networks.
This 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 improper boiler water chemistry. The results of a multi-million
dollar overhaul can be negated during start-up due to improper boiler water
chemistry.
Objectives
Upon successful completion of this course, the participant should be able to:
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.
