high pressure, high temperature
steam is converted to rotating
ergy, driving the generator at
$500 RPM to provide electric
current at 1890 volts.
Spent steam, at pressures with
in II ID. per square inch of a
perfect vacuum and at about
room temperature, is exhausted
from the turbine to the conden-
ser where it is cooled and con-
densed to water for pumping back
to the boiler through one of two
1850 II. P. boiler feed pumps and
another trip through the cycle.
To condenSe the spent steam,
$4,000 gallons of water per min
ute will be pumped from and re-
turned to the Yellowstone River.
Except for a very slight tempera-
ture increase, this water is re-
turned to the river unchanged and
uncontaminated.
The heavy natural silt loading
of the Yellowstone River and its
wide and violent variations in
level required that special de-
sign features be Incorporated in
the intake" structure, a separate
building located Immediately adj
jacent to the river.
Two specially designed pumps,
with parts made of abrasion re-
sistant alloys, will each supply
1900 gallons of water per min
ute to plant cooling services. The
intake structure will also house
a large fire pump, connected d.
rectly to the extensive plant area
fire main system.
To protect the plant site and
structures from undermining by
river erosion, 667 carloads of
heavy riprap rock, from the Liv-
ingstone quarries of the North
ern Pacific Railroad have been
anchored along the river bank.
Plant wastes will be conduct
ed to a special disposal lagoon"
built to specifications of public
health authorities.
Ignite fuel viii come to the
plant by rail from a new strip
mine being opened by the knife
River Coal Mining Company near
Savage, Montana. The enormous
appetite of the huge furnace viii
thus support another new and
stable industry in the Yellowstone
Valley.
A spur track into the plant site
will cross a large hopper, equip
ped with conveyors that can take
Ignite from the hopper at the
rate of nearly 600 tons or 10 car
loads per hour and discharge 1T
to the plant fuel bunkers or to
a storage area than can accommo-
date a compacted storage pile of
100000 tons of fuel.
Operating control of the overall
plant will be centralized in the
air conditioned control room. In
this specialized control area, un-
der the watchful eyes of skilled
operating personnel, automatic
equipment win continuously mon
itor all functions of the electric
generating process to maintain
stable conditions and peak process
efficiency. In case of emergency,
control room operators will have
available means for taking over
plant control from the control area
On a remote manual" basis.
The control room will be equip
ped with instruments displaying
all conditions of pressure, tenn
perature steam flow, electrical
values and other conditions i'm
portant to the generation process.
Closed circuit television receivers
will permit operators to view fur
mace flame conditions and boiler
drum water levels as images of
these conditions are transmitted
by television cameras continuous
ly scanning these critical func-
tons.
