SYSTEM AND METHOD FOR FLUID MEDIUM PREHEATING

摘要

The preheating system (100) for preheating fluid medium to be fed into the HRSG (200) includes a feed line (110) and a recirculation line (120). The feed line (110) is adapted to feed the fluid medium to a Low Pressure Economizer (LPE) (210) of the HRSG (200). The feed line (110) is adapted to be adjoined to an inlet (210a) of the LPE 210, and an outlet 210b of the LPE 210 enables therefrom the flow of the fluid medium in further portion of the HRSG (200). The recirculation line (120) is adapted to be connected between the outlet (210a) and the inlet (210b) of the LPE (210), in parallel to LPE (210) to recirculate the fluid medium to the LPE (210). A particular method of preheating using such a system is equally disclosed.
