It is proposed to employ superheaters to the entire boiler plant.

The boiler-room ceiling has been made especially high, and in this
respect the room differs from most power houses of similar
construction. The distance from the floor to the ceiling is 35 feet,
and from the floor plates over the boilers to the ceiling is 13 feet.
Over each boiler is an opening to the economizer floor above, covered
with an iron grating. The height of the room, as well as the feature
of these openings, and the stairway wells and with the large extent of
window opening in the south wall, will make the room light and
especially well ventilated. Under these conditions the intense heat
usually encountered over boilers will largely be obviated.

In addition to making provisions for the air to escape from the upper
part of the boiler room, arrangements have been provided for allowing
the air to enter at the bottom. This inflow of air will take place
through the southerly row of basement windows, which extend above the
boiler room floor, and through the wrought-iron open-work floor
construction extending along in the rear of the northerly row of
boilers.

A noteworthy feature of the boiler room is the 10-ton hand-power
crane, which travels along in the central aisle through the entire
length of the structure. This crane is used for erection and for heavy
repair, and its use has greatly assisted the speedy assembling of the
boiler plant.
