FUEL OIL HEATERS AND PUMPING EQUIPMENT
2.2.1
Storage Tank Heater
**************************************************************************
NOTE: Provide heaters for all fuel systems for No.
6 oil. The designer shall determine the
requirements for heating the other fuel oils from
the fuel oil supplier's specifications.
**************************************************************************
**************************************************************************
NOTE: For all aboveground heated tanks the design
shall include an economic analysis for the incentive
to insulate the storage tank.
**************************************************************************
Vertical type installed through a [_____] mm inch diameter manhole in top
of tank. Weld pipe connections to manhole cover. Entire assembly shall be
removable as a unit. Heater shall have the capacity to heat [_____] liter
per second gpm of No. [_____] fuel oil from [_____] degrees C F to [_____]
degrees C F when supplied with [[_____] kPa (gage) psig steam] [[_____]
liter per second gpm of [_____] degree C F hot water]. Coil shall have
steel tubes and be designed for working pressure of [_____] kPa (gage) psig.
Coil shall extend to within 150 mm 6 inches of tank bottom and shall
surround oil suction line. Heater shall be provided with [bottom] [side]
suction, inlet and outlet, drains, vent, thermometer and pressure gage.
2.2.2
Shell and Tube Heater
The shell, containing oil, shall be steel with steel or cast iron heads and
20 mm 3/4-inch o.d. by 16 BWG steel tubes with removable bundles rated for
1034 kPa (gage) 150 psig working pressure. Construct unit in accordance
with ASME BPVC SEC VIII D1 and design for [_____] kPa (gage) psig. Heater
shall have necessary heating medium connections such as inlet and outlet,
drain, vent, thermometer, and pressure gage. Heater shall have the
capacity to heat [_____] liter per second gpm of No. [_____] fuel oil from
[_____] degrees C Fto [_____] degrees C F when supplied with [[_____] kPa
(gage) psig steam] [[_____] liter per second gpm of [_____] degrees C F
hot water].
2.2.3
Electric Heater
Construct heater with steel shell and steel flanges and design for [_____]
kPa (gage) psig. Heater shall have sufficient capacity to heat [_____]
liter per second gpm of No. [_____] fuel oil from [_____] degrees C F to
[_____] degrees C F while operating on [_____] volts, [_____] phase,
[_____] Hz electric service. Control electric heater by a magnetic starter
with a manually operated "on-off" switch in series with a thermostatic
control with an adjustable range.
2.2.4
Oil Pumps
**************************************************************************
NOTE: Maximum suction lift for internal gear pumps
shall not exceed 34 kPa 10 inches Hg.
**************************************************************************
FS A-A-50561 suitable for No. [_____] oil at a viscosity of [_____] Pa.S SSU.
