After a comprehensive study on the feasibility of various kinds of working media including organic media, water has been finally selected as the most suitable working medium for Ranking cycle plant of waste heat recovery on board motor ships from a practical point of view. Hence, efforts to optimize the steam bottoming plant have led to the adoption of the dual steam pressure system, where the recovered electric power generation can be increased by 20 to 30% more than of a conventional single steam pressure type system. The system is designed to recover the main engine exhaust gas heat solely in order to simplify the system configuration and operation. Seventeen (17) sets of the system have been completed by May, 1980 and are running satisfactorily at sea. In addition, thirty eight (38) sets are on order. Several other improvements are newly proposed to be added to the present system to make it more effective in energy-saving and widen its application.
