  • Steam Ejector Pumps And Ejectors & Steam Ejector Theory
    Steam ejectors are designed to convert the pressure energy of a motivating fluid to velocity energy to entrain suction fluid and then to recompress the mixed fluids by converting velocity energy back into pressure energy. This is based on the theory that a properly designed nozzle followed
  • Recent Experience of Mechanical Vacuum Pumps Replacing Stem Ejectors in VOD and VD Processes (.pdf)
    ). LIMITATIONS OF WET VACUUM PUMPING FOR DEGASSING. Steam Ejectors. The steam jet ejector has been the mainstay for industrial vacuum pumping systems designed for operation. at pressures above 0.67mbar / 0.5torr. The low initial cost and apparent maintenance free operation of this. type of pump is well known
  • Robust Vacuum Solutions in Biomass Processing (.pdf)
    ), is the next step in the design. Wet technologies include liquid ring vacuum pumps, steam, ejectors and oil-sealed pumps. Dry technologies include claw, screw and Roots mechanisms and air ejectors. Correct system design is the concluding step in ensuring mechanical, electrical and regulations and standards
  • Recent Operating Experience with Dry Running Vacuum Pumps on Vacuum Degassing and Vacuum Oxygen Decarburising Systems (.pdf)
    dust load to pump system. can be high if filtration is poor. VOD gas temperature to pump system. should be <= 60oC. LIMITATIONS OF WET VACUUM PUMPING FOR DEGASSING. Steam Ejectors. The steam jet ejector has been the mainstay for industrial vacuum pumping systems designed for operation. at pressures
  • Vacuum Requirements for Steel Degassing (.pdf)
    dirty with large. amounts of metallic fines and oxide dust being generated. Historically much vacuum. degassing has been done using multiple steam ejector stages backed by hogging steam. ejectors or large water ring pumps. These systems traditionally require a lot of. maintenance, and consume extremely
  • Getting the Best from Your Investment
    Martin steelworks in Brescia, Italy, it was not traditional steam ejector technology that they recommended, but a 'dry' pumping system. This solution uses less energy than the traditional alternative, avoiding the issues of disposal of contaminated waste water and oil, and, crucially in this built

    and performance for steam/gas flow) and its associated software have been used in the re-design of a high-powered steam-driven motorcycle owned by the American comedian and "chat show" host, Jay Leno.

    the walls. Further, there is an introduction of steam along with the paper web which keeps the internal humidity high enough to get good condensation onto the cooled surfaces. The OptiSpray nozzle pipes extend only slightly to eliminate drop forming in the spray fans. Color mist forms color film
