Steam-Generating EquipmentFour new 500-hp. Babcock & Wilcox boilers equippedwith six-retort Taylor stokers supply the present steamrequirements of the plant. Three hand-fired Babcock& Wilcox boilers of 200-hp. rating each are held in re-serve from the old steam-generating equipment. Thenew boilers replace one 307-hp. and two 342-hp. units ofthe hand-fired type, which were removed in the recon-struction work.
