The heating surface ofeach apparatus is 606 sq. ft., the 132 ly^-in. tubes being ofbrass, 12 ft. long, seamless drawn, and tinned inside and outside. The current is generated by two three-phase alternatorswhich were manufactured by the Allgemeine ElektricitatsGesellschaft, of Berlin, and were supplied by the ElectricalCompany, of London. They are each capable of delivering, atany voltage, between 6300 volts and 6600 volts, 3750 kw to theexternal circuit, when working at 50 cycles per second on an. PLAN OF STUART STREET POWER STATION steam per hour. The cooling surface is 11,000 sq. ft., and iseffected by 3750 ^-in. outside diameter brass tubes, tinned in-side and out. The exhaust steam passes, before entering thecondenser, through an oil separator. The outside dimensionsof each separator are 9 ft. x 12 ft., and each is capable of dealingwith 95,000 lbs. of exhaust steam and extracting 95 per cent ofthe oil. In addition, there are two feed-water filters in thepump house, which are intended to remove the remaining smallpercentage of oil in the feed-water heaters are used. They are of the vertical inductive load, with a power factor of .87; or 4250 kw whenworking on a non-inductive load with a unity power factor asan ordinary continuous load, and 4900 kw for half an hour asan emergency load. As shown in the illustration, the framesare bolted up instead of being cast solid, a somewhat noveltype of construction, and designed largely to facil
