That the Iowa Railway and Light
| Company is taking advantage Of the
winter months to make every precau
! Improvements early in the spring, is
indicated by the work now being done
, by the company.
! Plans are being prepared for new
building to be used exclusively for
boiler room purposes, which Will be
built just as soon as work can be COM
menced in the spring. This building
will be absolutely fire proof, the roof
being of concrete on steel trusses, and
the walls of pressed brick. Even the
| windows of the building, and the
sashes, are to be of steel. and the win
dows are to be glazed with wine glass.
The building will be one story, 4Sx94.
Increase Capacity 800 Per Cent.
The company has just awarded a
contract for new Westinghouse
turbine of 2,10O horse power capacity.
which will be delivered early in the
spring.
The capacity of the station will be
increased 800 per cent. A new cooline
tower 4Ox70. with a system holding 1Oo,-
900 gallons. will be erected. Some IDEA
of the amount of water to be con-
sumed will be gained thru the knowl-
edge that it will require 5000 gallons OF
water per minute. forced thru the cool
ing tower by a powerful centrifugal
pump in order to condense the steam
supplied to the turbie. The condensed
water is returned to the boilers in a
Pure condition. thus preventing sedl-
ment and scale from forming.
1t will be possible. when the Improve
ments are made to the power house
next summer, to transmit power from
Marshalltown to Iowa City. thru CEDAR
RAPIDS. a distance of ninety -elght miles
to the east, and to Perry. thru Boone,
on the west, distance OF ninety miles,
In the event necessity demands power
NAV be received from Cedar Raplds'
where the main station Of 10000 horse
power is situated, or from the new
! 5000 horse power plant at Boone.
Company Spares No Expense.
| The officers Of the company have in
structed the company's engineers 70
spare no expense whatever o.s1nstall
| the latest and nest modern apparatus
| in the Marshalltown plant, and all in
spection of the work so far performed
| indicates that the plant Will be up-to-
date in every particular.
| A reserve dynamo is to be Installed
and placed in service in order to avoid
any possibility of an interruption IN
| the service. The large high tension
transformers of 1,400 horse power nave
been purchased. as has also all OF the
material for the lines leading east OF
Marshalltown to Tama, Toledo, ana,
eventually, to Cedar Rapids
These transformers transmit the cur
| rent at $4,000 volts. and they Will be
nlaced in a new fire proof building ad-
| Joining the power house. In this build
| ing will be placed the high tension
switches, lightning arresters. choke
coils. etc, that control and protect the
lines that are to radiate from this plant
Smoke Connection Finished.
The large smoke connection that
leads from the new 50O-horse power
boiler to the big concrete smoke stack
recently erected, has jus. been COM
pleted, and the new boiler will soon be
ready for service.
The power house will eventually con-
! tain four of these monster boilers, each
of which weighs fifty-seven tons, and
| is built to carry 200 pounds working
pressure.
There is a total of 1900 feet of four
inch boiler tubes. made Of hot drawn
seamless steel, in each boiler The
boilers are equipped with the most
modern CRATES, SCOT blowers, and other
auxiIiaries. All of the piping. fittings
and valves are extra heavy and all de-
signed for 200 pounds pressure.
The new concrete smoke stack is Isl
feet high, weighs 800 tons. and is large
enough to serve all the boilers. Inc
stack is twenty-four feet square at Its
