According to the study
of basic Rankin thermal cycle, the steam exhaust
pressure of a typical steam turbine toward the condenser, plays a great role in the efficiency and the net output power of the steam turbine, so most
surface condensers that are working in thermal power plants are kept at vacuum condition so that the maximum power of thermal cycle can be
achieved. The vacuum pressure at condenser leads to the entering of air and Non-condensable gases from turbine gland seals to
condenser so that the special air ejection equipment is being used to take
apart air from steam and vent it to out of condenser.In this study, a special steam and air separator mechanism in an evacuating system called “Aircooler” at a 16MW steam turbine condenser
is being studied and the Fluent CFD software is utilized to analyze the
behavior of steam plus air in a typical aircooler system of 16MW
