CHAPTER
7
A.
GENERAL
A well-planned maintenance program will help
avoid unnecessary down-time
or
costly repairs,
promote safety, and aid boiler inspectors. An
inspection schedule with a listing
of
procedures
should
be
established. It is recommended that a
ooiler room log
or
record be maintained. Record-
ing
of
daily, weekly, monthly, and yearly main-
tenance activities provides a valuable guide and
aids
in
obtaining economical and lengthy service
from Cleaver-Brooks
equipment
A boiler in-
spection schedule
is
shown at the end
of
this
chapter in Fig. 7-13, which can
be used as a
guide. It
is
important
to
realize that the frequency
of
inspection will depend on variable conditions;
such
as, load, fuel, system requirements, boiler
environment (indoor/outdoor), etc.
Good housekeeping helps maintain a
profes-
sional appearing boiler room. Only trained· and
authorized personnel should
be
permitted
to
operate, adjust
or
repair the boiler and its related
equi
pxnent The boiler room should be kept free
of
all material and equipment not necessary
to
the
operation
of
the boiler
or
heating system.
Even
though
the
boiler
has electrical and
mechanical
devices that make
it
automatic
or
semi-automatic
in
operation, these devices re-
quire systematic and periodic maintenance. Any
"automatic" feature does not relieve the operator
from responsibility, but rather frees him
of
cer-
tain repetitive chores providing him time
to
devote to upkeep and maintenance.
Alertness
in
recognizing an unusual noise, im-
proper gauge reading, leak, etc., can make the
operator aware
of
a developing malfunction, per-
mitting
prompt
corrective
action
that may
prevent extensive repairs
or
unexpected down-
time. Any leaks - fuel, water, steam, exhaust
gas - should be repaired and under conditions
that
observe
necessary
safety
precautions.
Preventive
maintenance
measures
such
as
regularly checking the tightness
of
connections,
loc~uts,
setscrews, packing glands, etc., should
be
mcluded
in
regular maintainance activities.
CHAPTER7-2
INSPEc;riON
AND MAINTENANCE
Periodic Inspection
Insurance regulations
or
local laws require a
periodic inspection
of
the pressure vessel by an
authorized inspector. Section I
of
Chapter 2 con-
tains in.(ormation relative
to
this inspection.
Inspections
of
this type are usually, though not
necessarily, scheduled for periods
of
normal
boiler down-time such
as
an
off
season. This
major inspection can often
be used
to
accomplish
maintenance, replacement, or repairs that cannot
easily
be done at other times
..
This also serves
as
a good basis for establishing a schedule for an-
nual, monthly
or
other periodic maintenance
programs.
While this inspection pertains primarily
to
the
waterside and fireside
surfaces
of
the pressure
vessel, it provides the operator an excellent
op-
portunity for a detailed· inspection and check
of
all components
of
the
bOiler,
including; piping,
valves, pumps, gaskets, refractory, etc.
Com-
plete cleaning, spot
pai~ting
or
repainting, and
the replacement
of
expendable items should be
planned for and taken care
of
during this time.
Any major repairs or replacements that may
be
required should also, if pqssible, be coordinated
with this period
of
boiler shutdown.
Replacement spare parts,
if
not on hand, should
be ordered sufficiently prior
to
shutdown.
CAUTION!
Cleaver-Brooks
genuine
parts
should
be
used
to
ensure
proper
operation
and
avoid
damage
to
equipment.
Qeaver-Brooks boilers are designed, engineered
and built to give long life and excellent service.
Good operating practices and conscientious
maintenance and care will promote efficiency
and economy from their operation and contribute
to many years
of
perfonnance.
The Cleaver-Brooks Total Protection
Plan in·
eludes a Planned Maintainance Program that
covers many
of
the items included
in
this chapter.
