OO-B-2925

4.4.2  Controls.  Each control and safety requirement shall be confirmed to be operational and functioning in accordance with the requirements of 3.10.

4.4.3  Equipment tests.  Control panels, insulation, valves, controllers, regulators, electric motors, dampers, and other related equipment shall be operated as part of the equipment tests.  The operation of this equipment shall be closely observed during the operational tests for possible defects or nonconformance.  The action of dampers, actuators, and valves shall be smooth

without backlash.

4.4.4  Emissions test.  The required emissions testing for particulates shall be conducted in accordance with the procedures of the governing federal, state, or local environmental agency as specified in 3.8.1.

5.  PACKAGING

5.1  Packaging requirements.  The preservation, packing, and marking shall be as specified by the contract or order.

6.  NOTES

(This section contains information of general or explanatory nature that may be helpful, but not mandatory.)

6.1  Intended use.  The baghouse is intended for removal of particulate emissions from the flue gas of coal fired boilers on land installations.

6.1.1  Section factors.  The following should be considered in the selection of a baghouse: Fungus resistant varnish conforming to MIL-V-173 should be used to coat electrical

components and circuit elements, including terminal and circuit connections, when the

baghouse is to be installed in humid conditions.  Components and elements inherently inert to fungi or in hermetically sealed enclosures or current-carrying contact surfaces should not be coated.

6.2   Acquisition requirements.  Acquisition documents should specify the following:

a.   Title, number, and date of this specification.

b.   Required operating design parameters for the following (see 3.7): (1) Maximum gas flow in ft3/min  (m3/s)).

(2) Minimum gas flow in ft3/min (m3/s). (3) Location of installation site.

(4) Elevation of installation site in feet (m) above sea level.

(5) Earthquake construction zoning requirements at the installation site.

(6) Required draft at boiler flue gas outlet, in inches-of water (Pa), at the maximum gas flow conditions.
