In order to reduce the difference in stress of the tubes through which heating steam is flowing in the case of heat exchangers where the tubes are concentrated in at least two horizontal bundles and where heating steam flows through the tubes and a power medium flows around the tubes, it is proposed that there are arranged at the intake openings of the tubes (1) through which the heating steam is flowing baffles (3) with different intake profiles (4) in such manner that within each bundle of tubes the intake profiles (4) will become smaller in direction of flow of the power medium to be heated.

In a heat exchanger having tubes combined into at least two horizontally arranged bundles with heating steam flowing into the tubes and a heating working medium flowing around the tubes, the tube bundles being streamed in series by the heating steam and circumflowed in series by the working medium and wherein the individual bundles are connected flow-upstream with a distribution chamber and flow-downstream with a drainable collecting chamber, the individual tube bundles having different heat exchanging surfaces such that the heating steam flow cross section of the tube bundles decreases in the direction of flow of the heating steam, the improvement comprising orifices with different inlet cross sections arranged at the inlet openings of each of the tubes streamed by the heating steam, said orifices being arranged such that within each tube bundle the inlet cross sections become smaller in the direction of flow of the heating working medium.
