The ship main engine is the main power for offshore navigation and operation, the proportion of waste heat to total heat efficiency is large, and the waste heat temperature of the waste gas is high. If the waste heat is directly discharged outwards, a large amount of unused heat is generated, and a great energy-saving effect can be realized by utilizing the generated heat. The heat utilization of the ship host makes the system fully utilize the residual heat generated by the operation of the host, thereby greatly improving the energy utilization efficiency of the host and reducing the emission, which is an advanced ship energy-saving measure.

The heat on the ship main engine can be divided into high quality and low quality, and the principle of 'energy supply according to quality' is followed, and each place is used. For low-quality waste heat, the waste heat is generally directly used as a heat source of other equipment, such as application in a sea water desalination device and a marine lithium bromide absorption refrigerator; the retention agent should be used from the viewpoint of energy saving under the high energy usage amount and high temperature condition. Generally, steam generated by the waste heat boiler drives the turbine generator to generate electric energy, and only then, the heat of the ship can be properly utilized, so that the heat is increased, and the energy is saved. However, for some types of ships, such as ocean engineering ships, the main scale and the ship type of the ships are limited, the number of main engines (or generator sets) arranged on the ship is large, the power is high, the working condition is complex, the chimney is narrow, the exhaust gas boiler is not suitable to be arranged, or the capacity of the exhaust gas boiler is limited, the fuel oil boiler is not required to be arranged any more, and the exhaust pipe waste heat of the main engines (or generator sets) cannot be fully and effectively utilized, so that waste is caused.
