Generally speaking, the mechanical
equipment which serves for the heat
ing, ventilating, plumbing, elevators,
lighting, signals and telephones in
North Dakotas new state capitol
building Is the most up-to-date and
efficient apparatus to be obtained.
Heating Of the building Is accomp-
lished by steam with direct radiation
located under the windows through
out the building. Approximately 35,-
600 square feet Of direct radiation,
comprising $50 units are required. In
addition, certain spaces such as Mem
orial Hall and the legislative foyer,
where the exposure Of glass surface
Is excessive, have indirect units en-
ploying electrically driven fans to re-
heat and re-circulate the air. The
capacity for heating In these various
units Is equivalent to 1900 square feet
Of direct radiation.
The typical radiator under each
window Il housed In . neat sheet
metal cabinet, set In tile Turing be-
fore the plastering was done. The
front Of the cabinet Is constructed Of
. heavy furniture steel panel made
removable for access to the radiator.
Each radiator Is fitted with = hand
controlled valve and thermostatic
trap. The back Of the radiator cab
met q thoroughly insulated to pre-
vent unnecessary heat leakage
through the outside wall.
Temperature regulation for the
building Is accomplished by an auto
matte regulation Of the steam deliv-
cred to eight zones In the heat sys-
tenn. This system includes . number
Of outdoor and indoor thermoGtats,
electrical and pneumatic valves for
the control Of steam and orifices Il,
the piping distribution for providing
uniform distributor and regulate the
use of steam to the radiators through
cut the building In such . manner -
to prevent over-eating In any section
Of the building.
In rooms having mechanical venti-
lation the radiators are equipped with
full thermostatic control, actuated
from room thermostats.
Steam Mains Under Roof
The steam distribution mains for
the administrative tower section are
located under the roof Of the tower
with downfeed risers to the radiation.
The steam return from this section
Of the building Is located on the base
ment ceiling. Steam distribution
mains through the Legislative section
are located on the basement ceiling
with upfeed risers to Ill radiators
throughout the section. The steam
returns from this section parallel the
supply mains. The entire heating
system - served from . boiler plant
located In the basement under the
east end OF the tower building. The
smokestack extends through the tow
er In = space adjacent to the eleva-
tors.
Coal Is delivered to the building In
trucks which supply overhead bunk
ers through coal holes at the drive
way grade. Ashes from the boiler
room are raised to the driveway BY
means OF an electrically driven ash
hoist which delivers the ashes In
closed containers directly on 10 Z
truck or wagon.
The boiler plant itself consists Of
three boilers, each having . capacity
Of 220 H. +. to serve $1,000 square feet
Of cast iron radiation. The boilers
are Of the steel portable fire box type,
welded and riveted for low pressure
heating operations with maximum
pressure Of Is lhs..
The boilers are each set high above
sprinkler type stokers. Ample COM
bustion space y provided BY means
OF solid brick wall construction hav.
ing first quality fire brick lining to
obtain highly efficient combustion Of
North Dakota Ignite fuels. The best
experience Of recent years covering
