PROBLEM TO BE SOLVED: To take out power with a low-cost structure and to effectively recover exhaust heat. SOLUTION: In this system, steam is generated by heat of exhaust gas from an engine 1 in a steam boiler 5, and a steam turbine 9 is driven by the steam. Gas-liquid mixture steam of an ammonia-water-based mixture fluid is generated in a steam generator 14 by heat of jacket cooling water from the engine 1 after cooling the engine 1, low-temperature steam components are separated from the gas-liquid mixture steam by a fractionator 17, and a low-temperature steam turbine 18 is driven by the low-temperature steam components. A power generator 22 is driven by both the turbines 9, 18, and the exhaust heat from the engine 1 is recovered as electric power. The gas-liquid mixture steam of the ammonia-water-based mixture fluid is generated by the exhaust heat after passing the steam boiler 5, the gas-liquid mixture steam is also supplied to the fractionator 17, and the heated low-temperature steam components are supplied to the low-temperature steam turbine 18 from the fractionator 17 to increase output of the low-temperature steam turbine 18.
