Effecive utilization of low level energy is becoming important from the view point of the earth environment and saving of the limited energy available. For a ship's propulsion plant a considerable amount of burnt gas at a medium level of temperature are exhausted to an atmosphere without any practical use after passing the economizer. Since the exhausted gas contains corrosive materials, heat recovery devices e.g. heat exchangers are exposed to the highly corrosive atmosphere caused by sulfuric acid especially at a water condensate temperature. This problem is an inevitable phenomenon and should be conquered before proceeding to the practical development of the system of heat recovery devices driven at a medium or low temperature level. In this paper authors describe the heat recovery system of two-stage reheating Rankine cycle composed of the heat exchangers with specially coated tubes for utilization of the exhusted gas energy of a main engine intergrating with the results of operation test of model plant and the corrosin test.
