concentration of [3500 ppm] [[_____] ppm], the carryover shall not exceed
[[_____] ppm] at the boiler nozzle, and moisture in the steam shall not
exceed [0.5] [1.0] percent.
2.1.5
Noise Levels
**************************************************************************
NOTE: The value for decibels for boiler shall be
that required for operating personnel and OSHA
requirements taking into consideration room design
and other requirements.
**************************************************************************
Conduct noise measurements and exposure analysis under the overall
supervision of an industrial hygienist or suitably qualified medical
officer from the Navy Regional Medical Center (NRMC). Safety personnel,
engineers and others who have been certified by the Chief, Bureau of
Medicine and Surgery (BUMED) also may supervise the work. Maintain
exposure limits for potentially hazardous noise levels of 85 dB, continuous
or intermittent and 140 dB peak sound pressure, impulse or impact. Sound
level meter shall conform as a minimum to the Type 2 requirements cited in
ANSI S1.4.
2.1.6
**************************************************************************
Note: Research local, state, and federal emission
standards and place any unusual or new requirements
in this specification section.
**************************************************************************
Provide fuel burning equipment, combustion control system(s) [and] stack(s)
[and emission control equipment] designed, installed, and when applicable,
adjusted so that emissions at any loading within the range of the boiler
output specified do not exceed federal, state, and local environmental
rules and regulations. Emission requirements to be considered include
sulfur oxides, carbon monoxide, particulate, or nitrogen oxides. In
addition, the density of any emission to the atmosphere, except during
start-up, cleaning of fires, or soot blowing, shall not exceed [No. 1] [No.
2] on the Ringlemann Scale or the Smoke Inspection Guide. The plant shall
otherwise conform to applicable Federal, State and Local regulatory
requirements. Air quality board "Permit to construct" [will be provided by
the contracting officer][will be obtained by the contractor].
2.2
Boiler Construction
2.2.1
General
Provide boilers constructed for specified design conditions and performance
requirements in accordance with applicable provisions of ASME BPVC SEC I,
and current addenda thereto, and FS F-B-2902. Mount [the] [each] boiler on
an internal structural steel base frame of welded construction designed to
serve as skids in shipment and to permanently support the unit off the
prepared foundation at the site. Assemble and install tubes, drums, and
headers in a manner to permit the boiler(s) to be drained dry by gravity.
