This boiler was also built by Babcock & Wilcox and was a single drum cross type water tube boiler and ran at a steam pressure of with a capacity of of steam per hour and was fed by a single chain grate stoker.

In 1907 the first turbines were installed, with two 750KW British Westinghouse Babcock water tube boilers, each having a steam capacity of 17, 000 lb / hr at 165PSI and 520degF . Smoke was directed into two smoke stacks each 175 feet high.

Fire tube boilers were the main type used for early high-pressure steam ( typical steam locomotive practice ), but they were to a large extent displaced by more economical water tube boilers in the late 19th century for marine propulsion and large stationary applications.

This boiler was also built by Babcock & Wilcox and was a bi-drum radiant type water tube boiler and ran at a steam pressure of with a capacity of of steam per hour and was fed by a single Babcock " Detroit " Rotograte stocker.

Steam was provided by two Foster Wheeler " D " type marine water tube boilers at 465 psi delivered to a De Laval steam turbine with 11 high and 7 low pressure stages, double reduction geared for a rating of 8, 500 shaft horsepower at 85 rpm to a four bladed bronze propeller of diameter with pitch.
