INSTALLATION FOR MODIFICATION OF OUTER TUBE SURFACES OF STEAM TURBINE CONDENSER USING SURFACTANT Russian patent published in 2023 - IPC F01K13/00 F28F13/18 

FIELD: steam turbine units.

SUBSTANCE: device for modifying the outer tubular surfaces of a steam turbine condenser using a surfactant that contains the annular space of the condenser with its outlet connected to the inlet of the circulating water supply system, a surfactant emulsion preparation unit, the corresponding inputs of which are connected to the corresponding outlets of the surfactant source and the source of hot chemically purified water, and the steam source, the outlet of the hot chemically purified water source is connected to the corresponding inlet of the annular space of the condenser, characterized in being equipped with a steam ejector and a condensate pump, while the outlet of the annular space of the condenser, free from connection to the circulating water supply system, is connected in series with the inlet of the condensate pump, the output of which is connected to the first inlet of the steam ejector, with its output connected to the inlet of the annular space, free from connection to a source of hot chemically purified water and form a circulation hydraulic circuit, the outlet of the steam source is connected to the second inlet of the steam ejector, the outlet of the surfactant emulsion preparation unit is connected to the line connecting the outlet of the annular space and the inlet of the condensate pump.

EFFECT: intensification of heat transfer in the condenser by increasing the heat transfer coefficient and the corresponding "deepening" of the vacuum by switching from film condensation to drip condensation.
