Abstract

Considering the fact that the heat transfer coefficient is variating along with condenser’s structure and the temperature of inlet cooling water

a calculating formula of entropy generation number for multi-backpressure condensers is given through theoritical analysis and deduction

and the influence of heat transfer surface and circulation ratio in every stage of the condenser upon the entropy generation number has been analysed. Taking the entropy generation number of a multi-backpressure condenser as the target function

the optimum structure of a multi-backpressure condenser has been obtained.
