DEVELOPING A STEAM BOILER SYSTEM WATER TREATMENT
PROGRAM. A complete boiler water treatment program takes into account industry-
developed guidelines for feedwater quality limits and boiler water quality limits. The
water treatment industry recognizes the suggested water limits developed by the
American Society of Mechanical Engineers (ASME), the American Boiler Manufacturers
Association (ABMA), and USACE. The limits developed by these three organizations
are not always identical; furthermore, the limits are actually only guidelines. In some
cases these limits have been exceeded by boiler operations without unacceptable
impacts; however, these limits should be considered as prudent, safe, and practical
guidelines (see Tables 3-8 through 3-20).
Organizing a Treatment Program. Once you have defined water
treatment requirements, organize personnel to implement the program. The
organization process consists of identifying a staff, training them to execute the
program, and integrating the program into overall installation management.
Operator Training. Operator training is essential to a water treatment
program. Operators should understand the operation of their specific plant and reasons
for specified procedures, including requirements of CFR Title 29, Part 1910.1200,
Hazard Communication. An understanding of reasons for, and results of, chemical
treatment is essential. Knowledge of thermodynamic and mechanical interactions of
plant equipment is important. The operator should be particularly aware of safe
operating procedures. Since internal chemical treatment of boiler water is a significant
factor in achieving reliable and efficient plant operation, operators should have an
understanding of the subject. Training should include the specifics of water treatment
and related costs.
Pretreatment Training. Pretreatment is necessary to ensure the quality of
the water to be treated for industrial use and to prevent or reduce associated problems
such as deposits and corrosion. Training might address these methods of pretreatment
(depending on the type of plant):
. Steam boilers, high-temperature water systems, and
cooling water systems all require treatment of feedwater to prevent or reduce deposits,
scale, corrosion, and microorganisms.
