Flash Steam Examples

Flash steam has exactly the same latent heat content as boiler steam. It will also give up its latent heat just as readily, to perform work in the process of condensing. If this latent heat is not put to some service, the heat energy that was used to produce it was partially wasted. Ideally, all the heat that was originally imparted to the water at the boiler (less the 180.07 Btu/lb [418.84 kJ/kg] heat of the saturated liquid at atmospheric pressure) will be used for some service by the time the condensate is returned to the boiler. The process of using flash steam created in one stage of a process in subsequent stages is called cascaded operation.
