    REGENERATIVE RANKINE CYCLE WITH FEEDWATER …

    2020-3-14 · REGENERATIVE RANKINE CYCLE WITH FEEDWATER HEATER. Let if 1 Kg of steam is entering to the turbine from boiler and as we have discussed that certain quantity of the steam will be extracted hence let Y kg of steam is extracted from the turbine at state 5 as shown in figure and therefore (1-Y) kg of steam will be expanded through the turbine

    3-Processes in HPH The feed-water heating process actually takes place in three distinct steps. First, the de-superheating zone cools the superheated steam to the point that the steam is saturated. Next, the condensing zone extracts the Latent Heat from the steam/water mixture to preheat the boiler feed-water passing through the tube side.
