comply with local and government requirements for equipment and safety as
well as applicable specifications.
3.4.2
Post Installation Inspection
A factory service engineer employed by the precipitator manufacturer shall
inspect the precipitator after installation is completed and prior to
startup to verify that the unit is installed in conformance with the
manufacturer's recommendations. Perform an air load test with precipitator
readings recorded.
3.4.3
Performance Tests
Perform field performance tests by an independent testing organization
acceptable to the Contracting Officer. Provide written notice to the
Contracting Officer, at least 20 calendar days before scheduled test date,
stating that equipment is being scheduled for test. Perform a trial run of
30 days minimum before actual test (operate boiler at least 60 to 90
percent load) to ensure that associated systems required for the test are
ready. Perform boiler tune-up to optimum efficiency prior to performance
test. The Contractor and the manufacturer's factory service engineer shall
witness the test. Perform tests in accordance with applicable state or
local methods. If no such methods or adaptations are required, then
perform the tests in accordance with EPA 40 CFR 60, Appendix A, Methods
1-5, 9 and 17. Perform tests at the maximum continuous rating for the
inlet gas conditions specified in paragraph entitled "Inlet Gas Conditions"
and, if applicable, at other operating conditions that are required for
approval by the appropriate regulatory agency. Test the precipitator for
efficiency by simultaneous testing of precipitator inlet and outlet
emissions. Conduct the efficiency tests after the precipitator has been in
operation for at least 45 days.
3.5
IDENTIFICATION
Fasten an aluminum, brass, or corrosion-resistant steel nameplate to the
equipment in a readily visible location by means of stainless steel Series
300 rivets or sheet metal screws. The nameplate shall contain data such as
the manufacturer's name, and model or series number. Indent or emboss the
information in the metal. Offset the nameplate a sufficient amount to
avoid being covered by insulation.
3.6
INSULATION INSTALLATION
3.6.1
General Insulation Requirements
Apply insulation with interruptions to permit access doors, inspection
doors, flanges, and other special features to be opened or removed for
inspection or maintenance without disturbing the insulation. Provide
boxouts around code stamping symbols and nameplates. Install double
thickness insulation with the joints of the two layers staggered. Fill
cracks, voids, and depressions in layers of insulation with suitable
insulating cements before application of another layer of insulation or
jacket application. Provide expansion joints in the insulation as required
to allow for thermal expansion movements which might cause cracks or tears
in the insulation. Install insulation between stiffeners and over
stiffeners so that stiffeners are completely insulated. Install additional
insulation or casing spacers between stiffeners so that a level surface is
achieved. The intent of this insulating procedure is to prevent a direct
metal path between the precipitator inside and ambient air. Securely wire
