PROBLEM TO BE SOLVED: To provide an exhaust heat recovery system that can improve energy use efficiency of an electric power generating system.SOLUTION: In one embodiment, an exhaust heat recovery system recovers exhaust heat of an electric power generating system. The electric power generating system includes: first heat source fluid; second heat source fluid heated by heat of the first heat source fluid; a fluid flow passage for conveying at least working fluid; an expander for expanding the working fluid for rotation; and a condenser for condensing the working fluid. The exhaust heat recovery system includes a water flow passage for supplying water to the condenser, cooling the working fluid in the condenser by using the water and conveying the water having a first temperature discharged from the condenser. The exhaust heat recovery system further includes a heater for heating the water from the water flow passage by using the first heat source fluid, the second heat source fluid or the working fluid to produce the water having a second temperature used as hot water or produce steam.SELECTED DRAWING: Figure 1 【課題】発電システムのエネルギ利用率を向上させる事が可能な排熱回収システムを提供する。【解決手段】一の実施形態によれば、排熱回収システムは、発電システムの排熱を回収する。発電システムは、第１熱源流体と、前記第１熱源流体の熱により加熱された第２熱源流体と、作動流体の内の少なくとも前記作動流体を搬送する流体流路と、前記作動流体を膨張させて回転駆動する膨張機と、前記作動流体を凝縮させる凝縮器とを具備する。排熱回収システムは、前記凝縮器に水を供給し、前記凝縮器内で前記作動流体を前記水により冷却し、前記凝縮器から排出された第１温度の前記水を搬送する水流路を具備する。排熱回収システムはさらに、前記水流路からの前記水を前記第１熱源流体、前記第２熱源流体、または前記作動流体を用いて加熱して、温水として使用される第２温度の前記水を製造するまたは蒸気を製造する加熱器を具備する。【選択図】図１
