Abstract

In a feed water preheater of horizontal type with an integrated desuperheater, the last deflection chamber of the desuperheater is provided with lateral steam outlet ports (13). As a result, the desuperheated steam does not reach the condensation zone directly as hitherto by passing into the free cross-section of the tube bundle but, instead, it passes into the free space surrounding the condensation bundle (2) on which it can then act from the outside inwards at minimum flow velocity.
