EXHAUST HEAT RECOVERY POWER GENERATING DEVICE AND SHIP WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an exhaust heat recovery power generating device which recovers the exhaust heat without introducing a heating medium route of high-pressure specification even when the exhaust heat temperature from an internal combustion engine is a high temperature.

SOLUTION: This exhaust heat recovery power generating device includes: exhaust heat recovery units 1 and 5 for recovering the heat by exchanging the heat between a heating medium having a boiling point higher than that of water and the exhaust heat of an internal combustion engine; an evaporator 60 for evaporating an organic fluid by exchanging the heat between the heating medium and the organic fluid; a power turbine 62 to be driven by the organic fluid evaporated by the evaporator 60; a generator 68 for generating power with a rotary output of the power turbine 60; a pre-heater 64 for pre-heating the organic fluid, which flows into the evaporator among the organic fluid passed through the power turbine 62; and a condenser 66 for condensing the organic fluid.
