c) Start boiler feed pumps.
d) Warm up boiler using manufacturer's recommendations.
e) Start cooling water system pumps.
f) Start condensate pumps.
i) Roll turbine using manufacturer's startup procedures.
For testing requirements, see Section 19 this handbook.
Trial Operation. After all preliminary checks and inspections are completed,
each piece of equipment shall be given a trial operation. Trial operation of all
equipment and systems shall extend over such period of time as is required to reveal any
equipment weaknesses in bearings, cooling systems, heat exchangers, and other such
components, or any performance deficiencies which may later handicap the operation of
main systems and the complete plant. All rotating equipment shall be checked for
overheating, noise, vibration, and any other conditions which would tend to shorten the
life of the equipment.
Main System Operation. Main systems should be trial operated and tested after
each individual piece of equipment has been trial operated and ready for operation. All
functional and operational testing of protective interlocking, automatic controls,
instrumentation, alarm systems, and all other field testing should be conducted during
initial plant startup. All piping should be visually inspected for leaks, improper
support adjustment, interferences, excessive vibration, and other abnormal conditions.
Steam traps should be verified for proper operation and integral strainers cleaned.
Operation Control. A system of control to protect personnel and equipment as
the permanent plant equipment and systems are completed and capable of energization,
pressurization, or being operated, should be established. The system should consist of
placing appropriate tags on all equipment and system components. Tags should indicate
status and the mandatory clearances required from designated personnel to operate,
pressurize, energize, or remove from service such equipment or systems. The controls
established should encompass the following phases.
a) Equipment or systems completed to the point where they may be energized,
pressurized, or operated, but not yet checked out, shall be tagged. The sources of
power or pressure shall be turned off and tagged.
