The steam is used in the process plants at various pressures depending upon the temperature requirements. The condensate from the high pressure steam when comes to low pressure, some part of the condensate get evaporated which is called as flash steam.
Recovering the maximum possible flash steam back to the feed water tank reduces the fuel consumption of steam boiler. Flash steam has substantial amount of heat which is ignored & vented to atmosphere in most of the process plants.
The percentage of flash steam generated from condensate is lower but the heat content of flash steam is high.
A properly designed flash steam separator can separate the maximum flash steam from the high pressure condensate & send it back to the feed water tank where it gets mix with the feed water increasing its temperature.
Higher the steam pressure used in equipment higher amount of flash steam will be generated from condensate.
