10. Turboblower Number Three Lubrication System: The
lubrication system for turboblower number three is located on the
floor of the building underneath the remains of the turbine. It
is manufactured by the Bowser Company of Fort Wayne, Indiana, and
consists of two oil coolers, two strainers, an oil conditioner,
and a 1/2 hp motor connected to a oil recirculation pump.
Installation Date: 1955.
11. Turboblower Number Three Surface Condenser: A 20,000
square foot capacity Ingersoll - Rand surface condenser is bolted
to the 72" diameter flanged steam connection located on the
underside of the bottom casing for the turbine. The centerline
of the condenser, which is laid out on a north-south axis, is
located 11'-1" from the floor. The condenser consists of a cast
iron shell which encloses a large number of 1/4" diameter tubes.
A 24" flanged inlet and a 24" flanged outlet connection are
located on the western side of the surface condenser near its
northern end for the purpose of circulating service water through
the tubes. Located on the underside of the surface condenser
shell near its center are two 4" diameter flanged condensate
removal connections.
Installation Date: 1955.
a. Air Ejectors: Two Ingersoll - Rand, Series M, Steam
Jet Air Ejectors are attached to the eastern side of the surface
condenser near its centerline. The 3*-3 9/16" long ejectors are
laid out vertically. Each ejector has a 2" diameter screwed
steam inlet connection at its lower end and a 4" diameter flanged
discharge connection at its upper end. Each ejector is attached
to the surface condenser by a 4" diameter flanged suction inlet.
The centerline of the suction inlet is 2'-7 5/8" below the flange
of the discharge connection.
Installation Date: 1968.
12. Turboblower Number Three Condensate Removal Motor/Pump
Assemblies: Located on the floor underneath the surface condenser
are two condensate removal motor/pump assemblies. Laid out on a
east-west axis, the assemblies straddle the centerline of the
surface condenser and are spaced 6•-4 13/16" apart. The northern
most assembly consists of a 25 hp Westinghouse Type CS Line start
Induction Motor rated at 1755 rpra which is connected by a gear
drive to an Ingersoll - Rand 370 gpm centrifugal pump. The
southern most assembly consists of a 24 hp steam turbine,
manufactured by the Terry Steam Turbine Company of Hartford,
Connecticut, rated at 1750 rpm which is connected by a gear drive
to an Ingersoll - Rand 370 gpm centrifugal pump.
Installation Date: 1955.
