for most applications. For installations where a
compressed air system exists or is to be installed,
a pneumatic starting system should be considered.
**************************************************************************
Engine starting system shall be the [electric] [pneumatic] type and be of
sufficient capacity, at the maximum temperature specified, to crank the
engine without damage or overheating. [Electric starting system shall
operate on a [24] [_____]-volt DC system utilizing a negative circuit
ground. A starting battery system shall be provided and shall include the
battery, corrosion resistant battery rack, intercell connectors, spacers,
automatic battery charger with overcurrent protection, metering and
relaying. Battery shall be in accordance with SAE J537. Battery charger
shall conforming to UL 1236 and be the current-limiting type with
overcurrent protection.] [Pneumatic starting system shall be as specified
in Section 15400A PLUMBING, GENERAL PURPOSE, for a working pressure of 1.03
MPa 150 psi.]
2.6.7.2
Lubrication System
Engine shall be provided with a pressurized oil lubrication system. System
shall include a lubrication oil pump that is engine driven. One full-flow
filter shall be provided for each pump. Filters shall be readily
accessible and capable of being changed without disconnecting the piping or
disturbing other components. System pressure shall be regulated as
recommended by the engine manufacturer. A pressure relief valve shall be
provided on the crankcase. Crankcase breathers shall be piped to the
outside. System shall be readily accessible for servicing such as
draining, refilling, and overhauling.
2.6.7.3
Coolant System
Engine shall include an automatic engine jacket water cooling system.
Water shall be circulated through the system with an engine-driven
circulating pump. [System coolant shall use a combination water and
ethylene-glycol sufficient for freeze protection at the minimum temperature
specified.]
2.6.7.4
Engine Heat Exchanger
Engine heat exchanger shall be of the shell-and-tube type construction and
be in accordance with ASME BPVC SEC VIII D1. Shell material shall be
carbon steel. Tubes shall be seamless copper or copper-nickel. Tubes
shall be individually replaceable. Unit's waterside working pressure shall
be rated for not less than 1,000 kPa 150 psig and factory tested at 150
percent of design working pressure. Water connections larger than 75 mm 3
inches shall be ASME Class 1500 flanged. Unit shall be provided with
gasketed removable covers, drains, and vents.
2.6.7.5
Engine Cooling Radiator
**************************************************************************
NOTE: An engine cooling radiator will be needed to
satisfy an engine's cooling requirements if cooling
tower water or heat recovery is not used.
**************************************************************************
Heat exchanger may be factory coated with corrosive resistant film,
provided that correction measures are taken to restore the heat rejection
