secured to the item of equipment.
2.2.2
Prevention of Rust
Unless otherwise specified, surfaces of ferrous metal subject to corrosion
shall be factory prime-painted with a rust-inhibiting coating and
subsequently factory finish-painted in accordance with the manufacturer's
standard practice. Heat recovery equipment exposed to high temperature
when in service shall be prime and finish painted with the manufacturer's
standard heat resistant paint to a minimum thickness of 0.025 mm 1 mil.
2.2.3
Diesel Engine Cooling
2.2.3.1
Antifreeze
[For ebullient cooling, the cooling system shall be suitable for a
combination of water and an azeotropic antifreeze compatible with the
equipment (methoxy propanol) as a cooling medium, hereafter called the
coolant.] [For cooling systems where steam is not required, an ethylene
glycol permanent type antifreeze shall be utilized. Size of cooling system
shall be based upon the use of an antifreeze solution which will protect
the system down to minus 45 degrees C minus 50 degrees F.] Antifreeze for
cooling the lube oil and auxiliaries shall be a permanent type suitable for
use with water, or the antifreeze solution specified above may be used and
shall be connected to a separate section of the waste heat condenser from
the engine coolant. Valve trim and materials shall be compatible for use
with the antifreeze solution. Operation of the cooling system shall be
fully automatic while the prime mover is running.
2.2.3.2
Water Jacket Temperature
For diesel engine ebullient cooling, jacket water temperature shall be not
lower than 110 degrees C 230 degrees F, nor higher than 120 degrees C 250
degrees F in the steam separator at all loads with a maximum differential
of [_____] degrees C degrees F for coolant in and out of the engine.
2.2.3.3
Construction
Where cooling system design is part of prime mover installation, components
other than the wasteheat condenser and condensate receiver or pump units
may be mounted on the engine skid extension. For any antifreeze cooling
system, a PVC makeup tank with an electric motor-driven pump unit shall be
provided as indicated. Pump shall be manifolded to allow using it as a
mixing unit by shunting the flow back to the tank. System fill shall be
[manual] [automatic] with feed into the piping system steel expansion tank
connection line as indicated.
2.2.4
Electrical Equipment
Electric motor-driven equipment specified shall be provided complete with
motors and necessary motor control devices. Motors and motor control
devices shall conform to the applicable requirements of Section 16402
INTERIOR DISTRIBUTION SYSTEM including requirements for hazardous area
locations. Unless otherwise indicated, motors of 746 watt 1 hp and above
shall be high efficiency type.
2.2.4.1
Motor Ratings
Motors shall be suitable for the voltage and frequency provided.
