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 environmental conditions
of the surrounding area. The Contractor shall perform the following tests
in the sequence as listed when feasible:
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 boiler[s] to the following strength and tightness tests:
a.
Watersides Including Fitting and Accessories: Hydrostatically
test watersides in accordance with the requirements of the ASME
BPVC SEC I. Since damage to the boiler components may have
occurred during shipping, the factory ASME label will not be
accepted as evidence of this test. Therefore, the final
hydrostatic test must be performed after the installation of the
boiler and its auxiliary components have been installed.
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
reached, and then hold. If in a 10 minute period the pressure
drop does not exceed 1245 Pa 5 inches water gage, the casing shall
be regarded as tight and accepted.
3.2.5.2
Boiler Inspection
The Boiler Inspector shall be on hand to witness the appropriate tests
which need to be observed in order to certify the safety of the boiler.
The inspection shall include the requirements of NAVFAC MO 324Inspection
and Certification of Boilers and Unfired Pressure Vessels. The Boiler
Inspector shall complete NAVFAC form 9-11014/40, Data Record Sheet; NAVFAC
form 9-11014/41, Inspection Report; NAVFAC 9-11014/32 Inspection
Certificate for each boiler after boiler has been inspected and found to be
safe. No boiler may be fired until it has passed the inspection of the
Boiler Inspector. Boiler inspection forms shall be submitted through the
Contractor to the Contracting Officer. Place Inspection Certificate under
framed glass, mounted on or near the boiler in a conspicuous location.
