Feed water for the boilers is taken from two return tanksin the basement below the boiler room, the supply being furnishedfrom the District supply, the condensers of the refrigerating systemand from the heating returns. The steam for the feed pumps istaken from an set of steam mains. There are eight Worth-ington feed pumps and eight Worthington circulating pumps, allset on glazed brick piers; the feed in the basement, and the circu-lating in pairs at the ends of the two rows of boilers, each pair crossconnected for interchangeability. The exhaust from the feed andcirculating pumps is utilized in two Baragwanath closed feed waterheaters overhead in the boiler room. The fittings throughout thesystem referred to above were made specially of cast steel by the. FIG. 10.—ONE OF TIIF. GEXER.\TING UNITS. Bethlehem Steel Company, and the valves, like the rest of the steamplant, were designed by Mr. Collins. Other pumps not noted abo\-e, but distributed around the powerplant or adjacent in the basement, are all driven by electric vacuum pump for the steam heating system is operated throughsingle-reduction gear by a 15-hp. 120-volt General Electric the plunger pump for elevating the discharge from the vacuumpump to a tank elevated 10 ft. above it is driven by a double-reduc-tion ,1-hp motor of the same make. The pump for supplying waterto the spirojector condensers has a double-reduction 20-hp GeneralElectric motor; and the two fire and house pumps, each of 1,000-gallons capacity per ninnite, with a pressure of 100-130 pounds atthe pump, are driven by single-reduction 90-hp Genera!
