![]() ![]() This paper will discuss the influence and control of these films as important parts of tube integrity that maintain the interface between a highly controlled thermodynamic working fluid and a potentially aggressive cooling water. Deposits and films which accumulate and grow on the tube's inside surface affect heat transfer capacity and in turn its ability to condense steam. Since the condenser is the heart of the heat reject system in operating power or process industry plants, as well as in ships, its reliability and efficiency affect the overall system performance. ![]() Cu-Ni alloys have established a long and successful history in seawater cooled heat exchangers and will be emphasized in this paper. The relatively thin-walled tube, selected primarily for heat transfer efficiency, becomes the critical component in condensers and other heat exchangers and must perform well over long periods of time under sometimes very difficult operating conditions. This thermally conductive wall is the tube in shell-and-tube type heat exchangers that make up a large percentage of such units in power plants, ships, the chemical process industry and in desalination. The heat exchanger is simply a device which directs the flow paths in such a way that the two streams are brought into thermal contact through a conducting wall while being kept physically separate. Effects of Dissolved and Non-condensed Gasesįor the vast majority of heat transfer equipment applications, the transfer of heat takes place between two fluid streams.The Application of Copper Nickel Alloys in Marine Systems.
