Abstract
In a method and device for protecting against erosion and/or corrosion steam pipes of the high-pressure stage of a power and/or steam generation plant saturated steam turbine, at portions of its low-pressure stage and at heaters of the heat exchanger installation of the power and/or steam generation plant, the major part of the water contained in the offtakes and the wet steam outlets of the high-pressure stage is separated out by centrifugal means. A first fraction of the steam partly dried by this means is superheated and/or final dried and then fed into the portions of the low-pressure stage of the turbine and a complementary fraction of the partly dried steam is fed to the heaters. The first fraction and the complementary fraction of the steam are dried together by centrifugal means after which the complementary fraction is final dried by centrifugal means.
