FIELD: power engineering.
SUBSTANCE: invention relates to power engineering and can be used in operation of network and regenerative heat exchangers for intensification of heat exchange. Result is achieved by a method for intensifying heat exchange using an aqueous emulsion of surfactants in a heat exchanger, which consists in disconnecting from external communications a shell-and-tube heat exchanger comprising an annular space, and modification of heat exchange surfaces on steam side during shutdown of heat generating equipment, characterized by that modification of heat exchange surfaces is carried out on a network or regenerative shell-and-tube heat exchanger with constant mixing and circulation of aqueous surfactant emulsion using a condensate pump at a temperature is of 20÷40 °C higher than temperature of steam condensed during operation of steam turbine plant.
EFFECT: reduction of fuel consumption for generation of electric energy and increase of electric energy generation.
