The waste heat recycling and utilization of marine diesel main engine power plants are of significant import-ance for enhancing the energy utilization efficiency and combat capabilities of naval vessels.This paper,based on the de-termination of the requirements for the waste heat recycling and utilization system,designs the overall structure of the waste heat recycling and utilization system for marine diesel main engine power plants.The system includes a waste heat recovery boiler system,a power turbine system,an organic working fluid power generation system,a steam turbine power generation system,a heat exchange system,and an energy management system.Finally,a simulation test was conducted on the waste heat recycling and utilization system of the diesel main engine power plant.The test results show that the system can effect-ively utilize the waste heat from the diesel main engine.The system's thermal recovery efficiency based on the Organic Rankine Cycle(ORC)can reach a maximum of 6.5％,and the efficiency of diesel main engine waste heat utilization can reach a maximum of 19％.
