description: This work is devoted to the study of the operating modes of steam-water heaters of return mains water as part of the CCGT. Steam from the selection of a steam heating turbine is used as a heating coolant. The steam temperature in the turbine sampling varies widely depending on the turbine power. The amount of steam overheating reaches 50 Â°C. Recently, plate heat exchangers have been used as steam heaters for mains water at the CCGT. The thermal capacity of such a heater should be determined taking into account three different heat exchange zones: superheated steam cooling, steam condensation and condensate cooling. The heat exchange process during the heating period is also affected by the temperature of the return mains water, which makes it necessary to regulate the flow of mains water in order to maintain the heater power. The paper presents a numerical study of the operating modes of plate steamwater heaters of mains water depending on the temperature of the heating steam, as well as the temperature of the return mains water, taking into account three heat exchange zones. A comparative study of the operating modes of plate and shell-and-tube horizontal heaters of mains water has also been carried out. The results of the numerical study can be used in planning the operating modes of the heating part of the CCGT during the heating period.
