  2. Vacuum ejector - Wikipedia

    en.wikipedia.org/wiki/Vacuum_Ejector

    A steam locomotive usually has two ejectors: a large ejector for releasing the brakes when stationary and a small ejector for maintaining the vacuum against leaks. The exhaust from the ejectors is invariably directed to the smokebox , by which means it assists the blower in draughting the fire.

  4. Diffusion pump - Wikipedia

    en.wikipedia.org/wiki/Diffusion_pump

    The steam ejector is a popular form of pump for vacuum distillation and freeze-drying. A jet of steam entrains the vapour that must be removed from the vacuum chamber. Steam ejectors can have single or multiple stages, with and without condensers in between the stages. While both steam ejectors and diffusion pumps use jets of vapor to entrain ...

  5. Vacuum brake - Wikipedia

    en.wikipedia.org/wiki/Vacuum_brake

    The large ejector is used to 'blow off' the brakes, by producing the vacuum, and is then shut off. The small ejector is left running continuously in order to maintain it. [4] The Gresham & Craven 'Dreadnought' ejector was a combination ejector, with both large and small ejectors within the same body. [5]

  6. Vapor-compression evaporation - Wikipedia

    en.wikipedia.org/wiki/Vapor-compression_evaporation

    Where Q d is the steam quantity at ejector delivery, Q s at ejector suction and Q m is the motive steam quantity. For this reason, a thermocompression evaporator often features a vapor condenser , due to the possible excess of steam necessary for the compression if compared with the steam required to evaporate the solution.

  7. Giesl ejector - Wikipedia

    en.wikipedia.org/wiki/Giesl_ejector

    A Giesl ejector is a suction draught system for steam locomotives that works on the same principle as a feedwater injector. This ejector (German: Ejektor, Flachschornstein or Quetschesse) was invented in 1951 by the Austrian engineer, Dr. Adolph Giesl-Gieslingen. The Giesl ejector ensures improved suction draught and a correspondingly better ...

    en.wikipedia.org/wiki/Vacuum_engineering

    Vacuum systems usually consist of gauges, vapor jet and pumps, vapor traps and valves along with other extensional piping. A vessel that is operating under vacuum system may be any of these types such as processing tank, steam simulator, particle accelerator, or any other type of space that has an enclosed chamber to maintain the system in less than atmospheric gas pressure.
