Beginning at the boiler room, there are eight. 225-hp Uab-cock & Wilcox boilers, carrying 160 lbs. steam pressure.These are supplied with feed water by four Worthingtonoutside packed plunger feed pumps.

These fans are driven by West-inghouse junior engines. The flue gases pass throughGreen economizers. The boiler firing is done by Roneymechanical stokers divided in two sections, four boilers oneach section.
