3. Specifying inlet and outlet tests to determine
efficiency or performance guarantees for cyclones
can cause problems in retrofits and some new units.
Cyclones with very short or angled inlet and outlet
ducts can cause inaccurate test data to be
collected. Therefore, specifying cyclone outlet
grain loading requirements may be more appropriate
than an efficiency requirement.
**************************************************************************
Field performance tests shall be performed by a testing laboratory with
experience in EPA's test methods and approved by the Contracting Officer.
Furnish a schedule of tests in writing to the Contracting Officer at least
10 calendar days before scheduled test(s) start date. Dust collector(s)
field performance test shall be conducted with [its] [their] respective
[boiler] [incinerator]. Operate each dust collector and its [boiler]
[incinerator] for at least 45 calendar days at approximately 25, 50, 75 and
100 percent loads and cycle [boiler] [incinerator] not less than two
complete cycles between 100 percent load and each partial load and back to
100 percent load. A trial run of 7 days minimum witnessed by the
Government, shall be performed before the 45 day test to ensure that all
associated systems required for the test are ready. The Contractor and the
dust collector manufacturer's field representative shall witness the trial
run and all tests. The testing laboratory shall furnish equipment, tools
and personnel necessary for testing, data gathering, and recording test
results.
a.
Particulate Tests of Dust Collectors: Simultaneous inlet and
outlet particulate tests on all mechanical dust collector(s) shall
be performed in accordance with EPA 40 CFR 60, Appendix A, methods
1 through 5 and 17. Method 17, in stack filtration, may be
performed as an alternate test to Method 5. Tests shall be
performed at maximum and partial load conditions herein specified
and report submitted to the Contracting Officer.
b.
Additional Tests: In the event that the mechanical dust
collector(s) do not meet performance requirements, failures and
deficiencies shall be resolved and additional tests shall be
performed by the testing laboratory as required to demonstrate
that the resolutions used permitted acceptable performance of the
mechanical dust collectors.

IDENTIFICATION
Provide an aluminum, brass, or type 304 or 316 stainless steel nameplate
and fasten to equipment in a visible location by means of rivets or sheet
metal screws of the same material as the nameplate material. Nameplate
shall contain data that consists of the manufacturer's name, model or
series number, and serial number. Indent or emboss the information in the
metal. Offset the nameplate a sufficient amount to avoid being covered by
insulation.
3.9
PAINTING
Clean the non-insulated exterior surfaces of equipment being furnished to
base metal in accordance with SSPC SP 6 and paint at the factory with two
coats of paint conforming to FS TT-P-28. Performed painting in accordance
