ON INTENSIFICATION OF HEAT EXCHANGE PROCESSES IN CONDENSERS OF STEAM TURBINES OF THERMAL AND NUCLEAR POWER STATIONS

This article reviews intensification of heat exchange in condensers of steam turbines. The importance of cooling system of thermal power station and its influence on operation efficiency of steam turbine assembly are described. Numerous existing procedures of heat exchange intensification in steam condensers are highlighted. The most promising methods are evaluated, importance of development of new designs is stressed. A method to achieve hydrophobicity effect on brass surfaces by means of surfactants is presented. A new approach is described related with formation of multilevel relief on surface of condenser tubes using laser radiation. Market of steam condensers of thermal power stations is analyzed including trends of its development up to the year 2020.
