In a steam condenser in which the steam is condensed on tubes which are grouped together in separate nests (2) and through which cooling water flows, the tubes, arranged in rows, of a nest enclosing a hollow space (13), a cooler (14) for the non-condensable gases in arranged in the hollow space. Two nests (2) are provided which are at a distance from one another and to which steam is admitted over their entire periphery, the nest form, irrespective of the external form of the condenser, being selected in such a way that first of all a convergent flow channel (15)--accelerating the steam--and then adjoining it a divergent retaining part (16)--deflecting the steam--are formed between the nests (2) on the one side and also between one nest each and the condenser wall. The cooler (14) for the non-condensable gases is located inside a nest in the plane in which, outside the nest, the convergent steam channel merges into the divergent part.
