[_____] degrees C degrees F outlet temperature with a water flow of [_____]
kg/second pounds/hour. The HTW generators shall be designed for a maximum
allowable working pressure of [_____] kPa psig at [_____] degrees C degrees
F. The equipment design and accessory locations shall permit accessibility
for maintenance and service. Design conditions shall be as follows:
a.
Site elevation, [_____] m feet.
b.
Ambient air temperatures, [_____] degrees C degrees F to [_____]
degrees C degrees F.
c.
Reference air temperature, 27 degrees C 80 degrees F.
The HTW generators shall be capable of operating continuously at maximum
specified capacity without damage or deterioration to the generator, its
setting, or firing equipment or auxiliaries. The generator shall be
operable automatically while burning the fuel specified. The HTW
generators shall operate on [coal meeting the requirement of paragraph FUEL
BURNING EQUIPMENT] [fuel oil conforming to grade number of ASTM D 396] [a
combination of coal and fuel oil conforming to ASTM D 396].
2.1.1
Capacity
Rated capacity shall be the capacity at which the HTW generators will
operate continuously without exceeding the furnace heat release, volumetric
and radiant, furnace exit temperature, and gas exit temperature specified.
Generator auxiliaries including fans, motors, drives, and similar equipment
shall be provided with at least 10 percent excess capacity to allow for
field variations in settings and to compensate for any unforeseen increases
in pressure losses in appurtenant piping and ductwork.
2.1.2
Electrical Equipment
Electric motor-driven equipment shall be provided complete with motors and
necessary motor control devices. Motors and motor control devices shall be
as specified in Section 16402 INTERIOR DISTRIBUTION SYSTEM including
requirements for hazardous area locations. Motors shall have electrical
characteristics and enclosure type as shown. Unless otherwise indicated,
motors of 1 hp and above shall be high efficiency type.
2.1.2.1
Motor Ratings
Motors shall be suitable for the voltage and frequency provided. Motors
373 W l/2 horsepower and larger shall be three phase, unless otherwise
indicated. Ratings shall be adequate for the duty imposed, but shall not
be less than indicated.
2.1.2.2
Motor Starters
