Abstract Marine diesel engine energy utilization rate has been hot spot of the world, because diesel engine energy utilization rate can be better, resulting in a lot of energy waste, energy problem has already become a very important issue in the process of economic development。 Continuously improve energy efficiency, reduce emissions of marine diesel engine exhaust, the survival of the human environment is to protect the environment for many people to study the subject。 

In this paper, the first chapter introduces the practical significance of the waste heat recovery of marine diesel engine cylinder liner water and the current situation of domestic and foreign recovery and utilization of this part of energy。 In the second chapter, the overall scheme of the marine diesel engine waste heat recovery system is designed。 The system mainly includes three subsystems, which are simulation and heat source system, waste heat recovery system and control system。 The third chapter of marine diesel engine jacket water heat recovery system of key parts of the design, including to cold and hot pipe design and calculation of the pipeline and pump design, selection of gas furnace and heat exchanger design。 The fourth chapter on the control components were designed, including on temperature sensor, flow sensor, a liquid proportional regulating valve, data acquisition card, PLC controller for the selection of design。 In the fifth chapter, the three-dimensional model of the experimental platform is built and the physical platform is built。 This paper presents a new application in marine diesel engine jacket water heat recovery system design program, on the basis of this scheme, focusing on the pipeline, a water pump, a gas stove, change heat exchanger, temperature sensor, flow sensor, the proportion of liquid control valve, data acquisition card and PLC control system for the calculation and selection of and complete physical platform is built。 

Key words: marine diesel engine; waste heat recovery; Heat exchanger。
