ENGINE AND TURBINE ROOMThe engine and turbine room is designed to take six 5000-kwsteam turbine units and three 3500-kw engine-driven three engines will be of the vertical Reynolds-Corliss type, August i, 1903.] STREET RAILWAY JOURNAL. 163 made by the Allis-Chalmers Company. They will be compoundcondensing, 46-in. and 94-in. x 60-in. stroke, running 75 r. p. m.,and rated at 4600 hp. They will have Corliss valves, and oper-ate under 100 degs. superheat to 125 degs. superheat. The fly-wheels are 28 ft. diameter, and weigh 320,000 lbs. Each enginewill have on its shaft a revolving field, 25-cycle, 3500-kw, three-phase General Electric generator, and each engine will havea Wheeler surface condenser. The exciter plant will consist oftwo 150-kw motor-driven generators, together with a storagebattery consisting of 78 cells, having a capacity of 60 kw, based. FIG. 12.—CIRCULATING WATER PLANT, SHOWING LOCATION upon the hour discharge rate. The piping, as can be seen fromthe accompanying plans. Fig. 10, will be practically in duplicate,consisting of duplicate headers and separate pipes to eachheader from all boilers and engines. CONDENSING PLANTEach of the Wheeler surface condensers has 10,000 sq. ft. ofcooling surface, and will be capable of condensing the steamfrom a 5000-hp engine when operating at 50 per cent surface condensers have copper tubes of iy2-m. twin vertical air pumps, 14 ins. and 38 ins. x 21 ins., havebeen ordered. In each engine exhaust next to the condenserin the basement is to be a Cochrane 48-in. oil separator. A Blake 30-in. automatic relief valve, with hydraulic control,will be placed in each engine exhaust, to allow the engine ex-haust to the atmosphere in case the condenser fails to engines will exhaust into one common main.
