In this case it was apparent that asomewhat lower boiler capacity than usual would be requiredfor the combined service. For moderate sized units a well-equipped boiler room requires from 2 to 25 square feet perboiler horse power: in some extremely oomnant arrange-ments, requiring as low as square feet per boiler horsepower. Tbo Fort Wayne arrangement W(u-ks out sniarefeet per boiler horse power. Assuming a capacity ratio boiler horsf power per kilowatt, the floor area tiien worksout slightly over one square foot per kilowatt for boiler roomalone. Now. for a fairly compact generating room In a stationof this size from to square feet per kilowatt are re-. Development in Turbine Stations—Figure 9, Plan and CrossSection of Turbine and Condenser Arrangement. The floor structure of the Ft. Wayne station is shownin detail in Figure 10. It consists of individual pairs oftransverse plate girders extending across the building undereach turbine bed plate. Short cross girders serve to tie thelongitudinal girders together at column intersections, thewhole forming bents or cradles between the several gen-erating units. Box columns divide the building width Intopractically three equal spans, these columns rising betweenthe several boiler batteries. Thus the weight of the gener-ating machinery is distributed between two building wallsand two rows of columns. Only in the case of the smallermachines and rotaries does any of the weight fall upon theareas intervening between columns. In order to insure evensettling, the precaution was taken of carrying footings forboth columns down to practically the same level so as toenco
