Definitions

  • Portable steam poiver' plants, andparticularly loconiotives,. generally include auxiliaries such as feed ⁇ Water pumps andllair pumps.
  • auxiliaries such as feed ⁇ Water pumps andllair pumps.
  • the power requirements of such auxiliaries are greater than in plantsusing only one boiler pressure, chiefly 'ifo-r the reason that each portion of the plant Which op'- 'erates at a'boiler pressure diverent from the other portions, requires a separate feed' Water pump.
  • Vthe gains obtained by the use ottivoor more pressures are reduced coiisiderablyby the increased ments of the auxiliaries.
  • theV steam for' operating the auxiliaries is taken irom thev high-pressure portion of the steam-generating plant,rand the exhaust'from these auxiliaries is conveyed -to the low pressure portion oft the poWer'plant, either to theloivpressure portion of the engine, or to the low- Vpressuresteam generator.
  • the invention is of especial advantage ivhen applied to locomotives of the type comprising a fire box constructed-as a boiler for the generation of high-pressure steam (say about atmospheres or more) and a longitudinal boiler for generating steam of (a lower pressure, say thecustomary pressure of'about l5 atmospheres. y
