218 THE MARINE TERMINAL OF THE GRAND TRUNK 
The building is to contain both boilers and power plant under one 
roof with fireproof dividing walls, and is to be 104 feet wide by 148 feet long, 
having a covered area of 15,392 square feet. The building will be of modern 
steel-frame construction, the walls and roof to be of reinforced concrete. 
There will be installed six 400 horse-power water tube boilers, supplied 
with automatic stokers, chain-grate type, such as are known to give good 
satisfaction with Pacific Coast coals. Provision is made for adding two 
extra boilers. ‘There is also a provision for the installation of an economizer, 
in case it is found that the load factor warrants the expense. Draught will 
be obtained by a steel or concrete chimney 175 feet high and 11 feet in 
diameter. An overhead trolley is provided for handling coalfrom storage 
to hoppers above the stokers and also for handling ashes. 
COAL HANDLING AND STORAGE. 
Provision is made for receiving coal both by water and rail. Coal by 
water will be received at the outer end of the pier for the unloading of which 
there is provided a standard grab-bucket installation, so arranged as to load 
cars beneath the hoppers, the cars to be handled by small yard locomotives 
to the coal pocket of 1,000 tons capacity, located adjacent to the boiler house. 
Coal received by rail will be delivered direct from the cars of the Grand 
Trunk Pacific Railway, which pass at the rear of the property, to the coal 
pocket approached by an incline. 
MAIN ENGINES. 
There will be two main engines of 900 horse-power each and while 
vertical reciprocating compound engines are shown and specified, using 
steam at 175 pounds pressure and 258 revolutions per minute, turbine 
engines will be considered as an alternative. 
CONDENSERS. 
Jet condensers are shown, but alternate figures will be taken for ser- 
vice condensers. The type to be used will depend upon local conditions 
as to the cost of water at the time of installation. Condensing water will 
be obtained through the rock cutting and shaft sunk within the power- 
house, the circulating water being handled by a vertical centrifugal pump 
operated by an electric motor.
