DANGER
WARNING
Inspection and maintenance should be performed only by trained personnel who are familiar with the
equipment. Failure to heed this warning could result in serious personal injury or death.
B. Periodic Inspection
Insurance regulations or local codes may require a periodic inspection of the pressure vessel by an authorized
inspector. Inspections are usually scheduled for periods of normal boiler downtime such as during an off
season. The major inspection can often be used to accomplish maintenance, replacement, or repair tasks that
cannot easily be done at other times. This also serves as a good basis for establishing a schedule for annual,
monthly, or other periodic maintenance programs.
While the inspection pertains primarily to the waterside and fireside surfaces of the pressure vessel, it provides
the operator with an excellent opportunity to perform a detailed check of all components of the boiler,
including piping, valves, pumps, gaskets, refractory, etc. Complete cleaning, spot painting or repainting, and
the replacement of expendable items, should be planned for and taken care of during this time. If possible,
any major repairs or replacements that may be required should be taken care of during the boiler shutdown.
Replacement spare parts, if not on hand, should be ordered well in advance of a shutdown.
Note: Cleaver-Brooks genuine parts should be used to ensure proper operation and to avoid
damage to the equipment.
Cleaver-Brooks boilers are designed, engineered and built to give long life and excellent service. Good
operating practices and consistent maintenance and care will promote efficiency and economy of operation
and contribute to many years of reliable performance from the equipment.
Cleaver-Brooks offers a Planned Maintenance Program that covers many of the items included on this chapter.
For more information on the Planned Maintenance Program, contact your local Cleaver-Brooks authorized
representative.
C. Fireside Cleaning
Soot and other noncombustible deposits are effective insulators and, if allowed to accumulate on boiler heat
exchanger surfaces, will reduce heat transfer to the water and increase fuel consumption. Soot and other
deposits can absorb moisture and may attract moisture in the form of corrosive acids that will deteriorate
fireside metal.
Inspection and cleanout should be performed at frequent intervals, depending upon the boiler's load, type and
quality of fuel, internal boiler temperature, and combustion efficiency. Stack temperature can be used as a
guide to determine cleanout intervals, since an accumulation of soot deposits will raise the stack temperature.
Access to the furnace for tube and refractory cleaning is provided through a hinged burner door at the front of
the boiler. When opening the burner door, first shut off the electrical and fuel supplies and then disconnect all
fuel lines at the burner watching to see that there is no interference with field installed piping, wiring, or other
obstructions. A temporary platform must be placed inside the furnace in order to protect the bottom drum
insulating refractory when working inside the furnace.
! DANGER
WARNING
To avoid the hazard of electrical shock, which could cause serious personal injury or death, the use of a low
voltage flashlight Is recommended when working Inside the boiler furnace area.
Tubes should be brushed with a wire brush to remove any soot or other accumulations. Refractory surfaces
should be cleaned, if necessary, with a soft bristle brush. Loose material should be vacuumed from the bottom
of the furnace.
