EMERGENCY TURBINE-GENERATOR UNITS OMALL but important arc the automatic emergency steam turbine-generator units which are installed in hospitals, state institutions, industrial plants, and oil refine These emergency units are installed to provide auxiliary power for lights, elevators instruments, and other critical apparatus which must continue to function when the normal power supply fails due to storms, operational difficulties, or accidents. Such installations form a neat, simple, compact, and reliable unit requiring no attendant, turbine is equipped with two solenoid valves which open on power failure and contn the steam flow to the turbine and the cooling water to the turbine bearings. Steam lines and turbine casings are drained through continuously operating traps so that th unit is ready to start on a moment's notice. Because of the importance of these emergency turbine-generator units, they are carefully checked and started up periodic The photographs on this page show two views of an Elliott 15-kw emergency turbine-generator unit installation in St. Luke's Hospital, Saginaw, Michigan. This u furnishes lighting for one operating room, halls, exits, and one dining room. The motors serving the boilers are also on the emergency lighting system, so as to provide continuous boiler operation in the event of a power failure. In this hospital the emergency operating room is on the ground floor: otherv a larger emergency generator would have been necessary so that the emergency power could also handle one elevator. The consulting engin responsible for this installation were Schmidt, Garden, and Erikson. I lew below shows the unit from the turbine end; the solenoid valve at left coat water to the bearings, solenoid valve at right controls the steam flow to the turb .11hunted on the generator is the Imill-in control. In tile housing is the voltage regulator andcontrolpanel. Ft PAGE 30 ixnvKitKA.x. actum.x iw i- -
