A MODERN CONDENSER DESIGN

The general construction of the UC-450 type main condenser manufactured by Kawasaki Heavy Industries Ltd is outlined in this paper. Water box design is discussed in detail with specific reference to calculation of velocity distribution and the prevention of inlet attack in the cooling water tubes. Test results on a 3,220-sq m condenser are presented giving distributions of water flow and heat transfer rate in tube nests. Some data are given on the effectiveness of various protection methods against erosion and corrosion in cooling water tubes.
