Abstract

A water preseparator (1) for steam turbine plants for the separation of water from the operating steam (SW) from a high-pressure steam turbine has a feed pipe (2) which extends over the starting section of a steam transfer pipe (4), wherein the two pipes are separated from each other by a gap (11) through which water (12) together with transporting steam (St) flow into a housing. The water discharges from the preseparator (1) via a water discharge pipe (6). the preseparator has structure for recycling of the transporting steam into the operating steam of the steam turbine plant, wherein this recycling structure has built-in fittings or a baffle (9) of the transporting steam, and also structure (4) for achieving a pressure drop, wherein the pressure drop exists between the gap (11) and a point at which the transporting steam is reintroduced into the operating steam (SW).
