STARTING AIR SYSTEM DRAWING FS 466 DESCRIPTION A complete 250 psi compressed air system has been provided to supply the diesel engines and their turning jacks with starting and operating air. The system consists of one motor driven and one gas engine driven air compressor, two air receivers, and the necessary safety valves, pressure gauges, controls, valves, fittings and piping. All compressors are Fairbanks-Morse Type "E" with water cooled cylinders, cooling water being supplied from a hopper. The motor driven compressor is provided with start, stop, and unloading controls; the engine driven compressor is provided with a stop and unloader only; starting is by means of a hand crank, The motor driven unit normally supplies the required air for plant operation; the engine driven unit is provided for emergency or standby use. The two starting air receivers are equipped with safety valves, pressure gauges and drain valves, the air supply header is equipped with a by-pass and pressure reducing valve, V-46, to reduce air pres- sure to 20 lbs. to supply instrument air. Blow down all compressed air receivers and piping once a week, open each of the receiver drain valves V-43 and V-44 for not more than 30 seconds or until sound of escaping air becomes uniform, indicating no slugs of condensate are passing through pipe. Also open high and low pressure blow down valves V-45 and V-50 to clean condensate out of lines. 3-13
