Flash Steam Separator

Condensate pipe carries approximately 90% (by volume) of flash steam, and 10% of condensate. This bi-phase condition occurs immediate downstream of the trap or discharge orifice. To recover the flash steam, the bi-phase fluid has to be separated into condensate and flash steam. As the pressure is low, the separation method cannot allow much pressure drop, but must separate the two phases efficiently, so that the flash steam is dry enough to use.Heating of feed water with the help of flash steam generated from boiler blow down. In continuous blow down system, especially where blow down rates are high as a result of poor feed water quality, Flash Separators can be used to recover energy from blow down. This can improve boiler efficiency substantially, and increase the steam generation of the boiler. (Every 6 degree C rise in feed water temperature results in 1% fuel saving.)
