EXECUTION
3.1
EQUIPMENT INSTALLATION
Install equipment in accordance with manufacturer's installation
instructions. Grout equipment mounted on concrete foundations before
installing piping. Install piping in such a manner as not to place a
strain on equipment. Do not bolt flanged joints tight unless they match.
Grade, anchor, guide, and support piping without low pockets. Feedwater
treatment feeders shall be mounted so that the top of the feeder is no
higher than 1219 mm 48 inches above the finished floor.
3.2
EQUIPMENT FOUNDATIONS
Locate equipment foundations as indicated, designed, and made of sufficient
size and weight to preclude shifting of equipment under operating
conditions or under abnormal conditions that could be imposed upon the
equipment. Foundations shall meet requirements of the equipment
manufacturer. Concrete and grout shall conform to Section 03300N
CAST-IN-PLACE CONCRETE.
3.3
BOILER CLEANING
Before being placed in service, boiler shall be boiled out for a period of
24 hours at a pressure not exceeding 83 kPa (gage) 12 psig. Solution to be
used in the boiler for the boiling out process shall consist of two pounds
of trisodium phosphate per 379 liters 100 gallons of water. Upon
completion of boiling out, flush out boiler with potable water, drain, and
charge with chemically treated water. Protect boiler and appurtenances
against internal corrosion until testing is completed and boiler is
accepted. Professional services are required for cleaning/treatment
process.
3.4
FIELD QUALITY CONTROL
Perform and furnish everything required for inspections and tests as
specified herein to demonstrate that boiler and auxiliary equipment, as
installed, are in compliance with contract requirements. Start-up and
operate the system. During this time, clean strainers until no further
accumulation of foreign material occurs. Exercise care to minimize loss of
water when strainers are cleaned. Adjust safety and automatic control
instruments as necessary to place them in proper operation and sequence.
Test instrumentation shall be calibrated and have full scale readings from
1.5 to 2 times test values.
3.4.1
Operate each boiler and appurtenances prior to final testing and insure
that necessary adjustments have been made. Provide testing equipment
required to perform tests. During this testing period, provide operating
instructions and training to persons tasked with operation of the boiler.
Tests shall be accomplished with both fuels on dual fuel units and include
the following:
3.4.1.1
Preliminary Operational Test
Operate the boilers continuously for a period of at least 8 hours to
demonstrate proper operability of the combustion control, flame safeguard
control, and safety interlocks.
