Starting from the energy quality basis to analyze condenser performance , from the fire with the transfer process to discuss the condenser heat transfer process exergy flow density , fire resistance , and the dynamic exergy loss parameters which impact Condenser fire factors and law passed , so as to improve the performance of the condenser , the improvement Condenser energy use and optimize the structure of the condenser to make the guidance to achieve the purpose of energy conservation . In this paper, based on thermodynamics , the second law , and the theory of non - equilibrium thermodynamics , in-depth study of exergy transfer theory , condenser structure . Condenser heat transfer process of the specific study of three components: cooling pipe outer surface of the steam condensation exothermic ; wall metal pipe internal and external surface itself and the thermal conductivity of the dirt layer ; tube inner wall of the cooling water of the exiled heat . Obtained Condenser in the steam side , the water side , and the wall inner side , the temperature of the outside of the distribution . As the basis for the use of fire by transfer theory links exergy transfer coefficient . Then Condenser design parameters , the parameters of fluid properties and process parameters together , a more detailed observation of the heat transfer process exergy transfer coefficient distribution . By analyzing the results , the final draw the following optimize the design and operation of the program . ( 1) by reducing condenser surface dirt , to change the flow of the fluid , changing the surface condition of the heat transfer surface , improve the convective heat transfer coefficient in the convective heat transfer process will largely improve the exergy transfer coefficients , thereby improving the efficiency of condensing steam to reduce the exergy loss . (2 ) design wall selection of high thermal conductivity of metal materials , can improve the thermal process exergy transfer coefficient ; the wall diameter decreases , exergy transfer coefficient of convective heat transfer process can be improved , thereby reducing the exergy losses. ( 3) reducing the temperature difference can improve the exergy transfer coefficient of heat transfer process , reduce the exergy loss in the heat transfer process , improve the flow of the working fluid , cold , hot fluid and the wall between the convective Heat with pass The coefficient increases proportional relationship .
