Flash steam Flash steam is released from hot condensate when its pressure is reduced.

Steam and Condensate - What is Condensate?

Condensate must be removed to allow the Heat Transfer. The condensate flows to the bottom where the steam trap will open and allow the condensate to flow to the receiver. There must be a positive differential pressure between the Heat Exchanger and the condensate line so that the condensate will flow out of the Heat Exchanger.Steam and Condensate - What is Condensate?Heat Exchangers.
