MARINE REHEAT CYCLES AND SYSTEMS EVALUATION

In light of recent improvements in steam propulsion resulting from the application of the reheat cycle, it is the purpose of the paper to present general and accurate comparative data, to aid others in the proper application of reheat and to evaluate its gains. Schematic engine room arrangements for a symmetrical plant as well as one designed for improved economics are presented for possible application on twin-screw, high-utilization, fast-turnaround vessels. Various methods for specifying reheat performance are reviewed and reasons for a new method are given. A heat rate method is proposed and developed to help inprove standards of calculation and specification. Heat rate factors are provided on most engine room components to allow trade-off studies. Typical all-purpose fuel rate curves for five cycles are shown for 30,000 to 200,000 shp. Representative heat balance data are given to allow the marine designers to size or specify components by interpolation on a preliminary basis.
