SYSTEMS to specify the fuel supply system if natural
gas fueled engines are specified.
**************************************************************************
[The diesel fuel supply from the main diesel fuel storage to the day tank
shall be as specified in Section 13202 FUEL STORAGE SYSTEMS.] [The natural
gas fuel supply system shall be as specified in Section 02556A GAS
DISTRIBUTION SYSTEM and Section 15190A GAS PIPING SYSTEMS.]
2.3.8
Main Fuel Storage Tank
**************************************************************************
NOTE: The location of this tank is important for
day tank draining and day tank fuel supply. The
appropriate type and location should be determined
by costs and operational requirements and should
follow local, state, and Federal Environmental
Protection Agency regulations, UFGS-13202A and
NFPA-30. Delete this paragraph if natural gas
fueled engines are specified.
**************************************************************************
The main fuel storage tank is specified in [Section [13202 FUEL STORAGE
SYSTEMS][[_____]]][_____].
2.4
LUBRICATION
**************************************************************************
NOTE: Delete the adjustable requirement for
pressure regulation on the pressurized lube oil
system for engines smaller than 1,000 kW (1,350 hp).
**************************************************************************
Each engine shall have a separate lube-oil system conforming to NFPA 30 and
NFPA 37. Each system shall be pressurized by engine-driven pumps.[ The
system pressure shall be adjustable and regulated as recommended by the
engine manufacturer.] A sump tank shall be furnished as required. The
lube-oil pump shall draw oil from the oil pan or sump tank through a mesh
intake strainer and force it through a lubricating oil cooler and a single
or duplex full-flow strainer into the engine. The pump shall be protected
by a relief valve to bypass the oil into sump. A portion of the oil from
the sump shall be bypassed through a lubricating oil filter and back into
the engine oil pan or sump. The lubricating oil temperature shall be
regulated by means of an automatic temperature regulator which will control
the amount of bypass oil around the cooler. The system shall be readily
accessible for service such as draining or refilling. Each system shall
permit the addition of oil and have oil-level indication with the set
operating.
2.4.1
Pump Filters
One full-flow, duplex, 80 micron filter shall be provided for each pump.
The filter shall be readily accessible and capable of being changed without
disconnecting the piping or disturbing other components. The filter shall
have inlet and outlet connections plainly marked. An indicating
differential pressure gauge shall be provided across the filter.
