Profile:
Steam ejectors are based on the ejector-venturi
principal and operate by passing motive steam through an expanding
nozzle. The nozzle provides controlled expansion of the motive
steam to convert pressure in to velocity which creates a vacuum
with in the body chamber to draw in and entrain gases or vapours.
The motive steam and suction gas are then completely mixed and then
passed through the diffuser or tail, where the gases velocity is
converted in to sufficient pressure to meet the predetermined
discharge pressure.
Steam ejectors are used in a variety of
applications in the process, food, steel and petrochemical
industries. Typical duties involve filtration, distillation,
absorption, mixing, vacuum packaging, freeze drying, dehysrating
and degassing. Ejectors will handle both condensible and none
condensible gas loads as well as small amounts of solids or
liquids.
Staging of Ejectors is required for more economical operation when
the required absolute vacuum level is reduced. Two-Stage
Steam Ejectors generally cover vacuum ranges between 3mm
HgA to **0mm HgA, however depending up on actual operating
conditions a Single Stage may be more economical if at the upper
limit of the operational envelope, or a Three Stage Ejector System
if conditions are at the lower end.
Two-Stage Steam Ejectors consist of a primary High
Vacuum (HV) Ejector and a secondary Low Vacuum (LV) Ejector.
Initially the LV ejector is operated to pull vacuum down from the
starting pressure to an intermediate pressure. Once this pressure
is reached the HV ejector is then operated in conjunction with the
LV ejector to finally pull vacuum to the required pressure.
Two-Stage Steam Ejectors is Condensing type.
Condensers can be used as inter-condensers, and after-condensers,
all of which help to reduce the gas load being passed on to the
next ejector stage. This helps to reduce motive steam consumption
and also allows smaller ejectors to be used with in the system.
In condensing steam turbine systems, Two-Stage Steam
Ejectors has function to extract air and other
non-condensing gases from the sealed condenser, and in such way to
maintain vacuum which corresponds to ratio of cooling water
quantity, cooling water temperature and cooling surface.
