Abstract: A set of heating system capable of recovering the waste heat from the jacket water of the main engine and auxiliary engine has been designed in view of the fact that the energy conversion rate of the conventional diesel engine is less than 50% and the special requirements of the shipowners for energy saving and emission reduction. The waste heat generated by the main engine and auxiliary engine can be utilized to heat the oil bunker, sludge tank, cargo oil cleaning water and air conditioner, in order to achieve energy-saving and the improvement of the fuel utilization efficiency, and to meet the necessary heat energy for the ships under the working conditions of berthing, cargo handling, entering and leaving port and normal navigation, as well as during the tank washing. A simple and practical method is used to improve the total efficiency of the marine power plant. It can provide reference for the utilization of the waste heat for the small and medium ships.
