Water Boiler Treatment Practice
Details :
This course will provide a comprehensive review of the
principles of boiler water conditioning. The ASME and EPRI Boiler Chemistry
Guidelines will be developed. Oxygen control by means of desecration and
chemical treatment will be reviewed. Boiler design principles will be
developed, including heat transfer, circulation effects, and high-pressure
requirements. The special requirements of HRSGs will be reviewed in depth.
The chemistry and control of
phosphates, chelant, and sludge conditions were be reviewed in depth. Problems
and solutions associated with steam purity and condensate corrosion will be
covered in detail with several practical examples. Guidelines for chemical
cleaning will be developed.
The discussion of the
metallurgical analysis of failed boiler tubes includes a workshop. The course
concludes with destructive and non-destructive options for boiler tube
inspection.
Upon successful completion of
this course, the delegates will be able to:
· Have an
understanding of the chemistry of boiler water treatment for scale, corrosion,
and carryover control, treatment options for the gamut of industrial boiler
system pressures, the options and precautions associated with boiler chemical
cleaning, and metallurgical analysis of failed boiler specimens.
· Have a
strong understanding of the chemistry of ion exchange resins and the operation
of systems using ion exchange resins for water purification, including system
and vessel design parameters. The course also provides practical options to use
when troubleshooting resin-based systems
This is course is intended to those new to the field take away a
good multi-discipline understanding of the issues involved in their work. It
helps them in becoming productive quickly and in building a knowledge framework
that will help them identify, understand, classify and remember on the job
learning and experiences.
