Uses of titanium in heat exchangers for condensers of power plants, geothermal power generators, and OTEC

Because of its excellent corrosion resistance to sea water, titanium has increasingly been used in condensers in power plants. Air-cooling units of the condensers have for a long time used titanium tubes for preventing problems caused by ammonia. But recently, condensers using both titanium tube plates and titanium tubes have been made. Also, in a binary circle test plant, which reuses hot water in a geothermal power generator, titanium was used in heat exchangers for its high corrosion resistance to hot water. In a test plant for ocean thermal energy conversion, titanium tubes and tube plates are used. This paper explains the use of titanium in such heat exchangers. (author)
