Steam Jet Ventilators convey air, gases and vapours against small pressure differences up to approximately 300 mbar. Their basis operating principle is the same as that of a Jet Pump. The high velocity steam emerging from the motive nozzle draws in and accelerates the suction medium, be it air gas or vapour. The kinetic energy of the resultant steam/air or steam/gas mixture, is then re-converted to pressure energy in the diffuser.
Steam Jet Ventilators are used:
- draw off stale air or noxious gases and vapours from working and storage areas
- to ventilate tanks, for example on ship-board
- as forced blast blowers, or stack ventilators from boiler combustion chambers
- to draw off and mix exhaust gases from thermal after-burning
Steam Jet Ventilators are available in the following standard materials:
Carbon steel, rubber-lined steel, cast iron, stainless steel; or in special construction from titanium, hastelloy, and many others.
Steam Jet Ventilators are available in three different constructions:
- without head, giving free access to the entrained media
- with axial suction connection
- with lateral suction connection
