The invention discloses a marine hybrid power propulsion system, which comprises a gas turbine, a gas-liquid heat exchanger and a ship body, a power system and an electric control system are arranged in the ship body, and the power system comprises a turbine and a propeller coaxially connected with the turbine; the exhaust end of the gas turbine is connected with the gas inlet end of the gas-liquid heat exchanger, and a steam outlet of the gas-liquid heat exchanger is connected with the turbine of the ship body; and the current output end of the gas turbine is connected with the current input end of the electric control system of the ship body. Heat energy and electric energy of the gas turbine are used as hybrid power, on one hand, the gas turbine converts chemical energy of fuel into electric energy which can be used for controlling the posture of the ship body and conducting vector propulsion on the ship; on the other hand, waste heat of tail gas is recycled through the gas-heat heat exchanger, and steam sprayed out of the gas-heat heat exchanger is used for directly pushing the turbine of the ship body to do work, driving propellers to rotate and pushing the ship body to advance; and vector propulsion and thermal propulsion items are combined, and the combined action efficiency can reach 80%-90%.

    本发明公开了一种船用混合动力推进系统,包括燃气轮机、气液换热器和船体,船体内设有动力系统和电力控制系统,动力系统包括涡轮,以及与涡轮同轴连接的螺旋桨;燃气轮机的排气端与气液换热器的进气端连接,气液换热器的出汽口与船体的涡轮连接;燃气轮机的电流输出端与船体的电力控制系统的电流输入端连接。本发明利用燃气轮机的热能和电能作为混合动力,一方面燃气轮机将燃料的化学能转化为电能,可用于控制船体姿态,对船进行矢量推进;另一方面通过气热换热器将尾气的余热回收利用,气热换热器喷出的蒸汽用于直接推动船体涡轮做功,带动螺旋桨转动,推进船体行进;矢量推进和热力推进项结合,联合作用效率可达80%~90%。
