Abstract (en)

[origin: EP2442061A2] The device (1) comprises a heat exchanger (2), which has a feed line (3) for a medium (16) from a medium inlet (4) for a heat exchanger inlet (5), and a discharge line (6) from the heat exchanger outlet (7). A primary bypass (8) is provided, which is formed from the medium inlet to the discharge line, and a secondary bypass (9) from the feed line to a medium outlet (10) and valves (11,12,13,14), such that the medium flows from the heat exchanger outlet to the heat exchanger inlet. An independent claim is also included for a method for operating a heat exchanger of a steam generating unit.
