into the plant, and provide steel above an opening between floors to hoist large
equipment to an upper level.
Metering. Meters shall be provided on fuel lines, electrical and water
16.7
services to the buildings, and to the major equipment and boilers in the building.
Steam output metering of the header and at each steam generator shall be provided for
periodic reports and testing.
Refer to MIL-HDBK-1003/6, under Drainage and NAVFAC DM-3.1,
16.8
Plumbing Systems.
16.9
Seismic Design Criteria
Power Plant Buildings. Power plant buildings shall be in accordance with
16.9.1
Seismic Design for Buildings, NAVFAC P-355.
Piping. All piping systems shall be designed to permit freedom of movement of
16.9.2
the pipes in all directions. Pipe penetration through building walls and floors shall
be made through pipe sleeves and with swing joints or other means of permitting
independent pipe movements.
All piping critical to the operation of the power plant shall be steel,
if possible, in lieu of a brittle material.
Cast-iron or cement-asbestos pipe shall not be used for condenser
cooling waterlines.
Equipment. All mechanical equipment and tanks shall be securely anchored to
16.9.3
their foundations. Supports for equipment shall be steel in lieu of cast iron.
Controls. Control systems shall be designed so that loss of the control media
16.9.4
(air or electricity) will leave the control in a fail-safe position.
16.10
Architectural Criteria
Outdoor and Semi-Outdoor Plants. Boiler plants and generators, completely
16.10.1
outdoors, may be feasible in warm and temperate climates, thereby reducing construction
costs. Proper measures against freezing of stationary water must be made.
Definitive steam electric-generating plants have semi-outdoor boilers.
Weatherproofing equipment for outdoor service saves a good part of building
construction. However, weatherproofing equipment makes operation and maintenance more
difficult.
An economic study should decide whether indoor or outdoor housing
should be used.
