description: The topic of the final qualifying work: "Computational analysis of circuit solutions when using steam-water plate heaters of return mains water as part of the PSU-TPP". This master's thesis is devoted to the study of the modes and features of the operation of plate heaters used recently as part of the PSU-TPP for heating the return network water with selected steam turbines. The use of superheated steam from the selection of turbines leads to the need to take into account the cooling zone of superheated steam to the saturation state. In addition, the design feature of the plate heat exchanger is that the significant size of the condensate collectors and their location in the plates inevitably contribute to a significant cooling of the condensate. Manufacturers of plate heat exchangers in the specifications for the heat exchanger, as a rule, do not take into account these processes, which leads to a decrease in the actual capacity of the heater in comparison with the data of the specification.In this paper, a numerical solution is given for various operating modes of a plate heater for return mains water, taking into account three cooling zones of heating steam. Based on the results of the calculations performed, an additional number of plates will be installed in plate heat exchangers in order to increase their capacity by 40%. Regulating the flow of mains water through plate steam heaters according to the proposed method will make it possible to better load the selections of steam turbines during the year.
