| Research Abstract |
The purpose of this study is the development of plate heat exchangers made by steel materials. We have known that ozone has a corrosion protective effect on steel dipped in seawater. As for cooling water of heat exchangers for ships, seawater is used. So titanium are adopted for prevention of rust for the seawater, plate of heat exchanger is made of titanium. The price of titanium is high. If the plate is made of steel instead of titanium, we can produce the heat exchangers cheaply. And a lot of cheap heat exchangers will be used. For the development of steel plate heat exchangers, we carried out each experiment and investigated the relations between prevention of rust effect and seawater circulation, ozone density, seawater flow, seawater temperature. And we investigated the relations between ozone, TRO and prevention of rust effect too. We finally manufactured a plate made by steel and experimented on the prevention of rust effect by using a heat exchanger.
