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.
Steam condenser in which the steam is condensed on tubes which are grouped together in separate nests and through which cooling water flows, the tubes, arranged in rows, of a nest encircling a hollow space in which a cooler for the non-condensable gases is arranged, comprising two nests spaced apart at a distance from one another and to which steam is admitted over their entire periphery, said nests being surrounded by a housing comprising a condenser wall, the nest shape forming an unobstructed convergent flow channel for accelerating the steam and an adjoining unobstructed divergent retaining part for decelerating the steam between the nests and also between one nest each and the condenser wall, and said cooler for the non-condensable cases is located inside a nest.
