3.2.4.5
Fans, Heaters, Pumps, and Motors
Test draft fans, fuel oil heaters, fuel pumps, and electric motors to
determine compliance with the referenced standards. Standard symbols and
certifications from the referenced organization may be accepted at the
discretion of the Contracting Officer. Closely observe the operation of
fans, fuel oil heaters, fuel pumps, and electric motors for possible
defects or nonconformance.
3.2.5
Boilers and Auxiliaries Tests and Inspections
The Contractor, with qualified personnel provided by the Contractor, shall
make tests and inspections at the site under the direction of and subject
to the approval of the Contracting Officer. Furnish direction of the
Contractor's boiler plant personnel in the operation of each boiler and
appurtenances through the entire testing period, from the respective
manufacturer's representatives and consultants and ensure that necessary
adjustments have been made. The Contractor shall notify the Contracting
Officer in writing at least 7 days in advance that equipment is ready for
testing. The Contractor shall furnish testing equipment, including gages,
thermometers, calorimeter, Orsat apparatus, thermocouple pyrometers, fuel
flow meters, water meters and other test apparatus and calibrate
instruments prior to the test. Draft, fuel pressure and steam flow may be
measured by permanent gages and meters installed under the contract. The
Contractor is responsible for providing an analysis of the fuel being used
for the tests. Control of noise levels developed by exhaust steam shall be
as directed by the Contracting Officer to satisfy the environmental
conditions of the surrounding area. The Contractor shall perform the
following tests when feasible in the sequence as listed:
a.
Strength and tightness tests
b.
Standards compliance tests
c.
Preliminary operational tests (steady state combustion test and
variable load combustion test)
d.
Tests of auxiliary equipment
e.
Feedwater equipment test
f.
Capacity and efficiency tests
3.2.5.1
Strength and Leak Tightness Tests
Subject boilers to the following strength and tightness tests:
a.
Watersides Including Fitting and Accessories: Hydrostatically
test watersides in accordance with the requirements of ASME BPVC
SEC I The ASME label will be accepted as evidence of this test.
b.
Boiler Casing, Air Casing, and Ducts: Test air casing and ducts
exterior to the furnace pneumatically at the maximum working
pressure. Use the soap bubble method to verify tightness. Test
gas sides of boilers normally operated under pressure for
tightness at one and one half times the predicted operating
pressure in the furnace at maximum continuous output. For this
test, tightly seal the boiler with a suitable means to blank off
openings. Admit air to the boiler until the test pressure is
