<P>PROBLEM TO BE SOLVED: To enhance efficiency of waste heat recovery and suppress fluctuation of water temperature during waste heat recovery. <P>SOLUTION: This waste heat recovery system includes: a heat exchanger 4 generating hot water by heating water by waste heat of an engine 2; a water supply tank 6 storing the hot water and supplying water to a boiler 5; a circulation pipe line 7 having a going pipe line 7a supplying water within the water supply tank 6 to the heat exchanger 4 and a return pipe line 7b returning hot water generated by the heat exchanger 4 to the water supply tank 6; a branch pipe line 12 interconnecting the going pipe line 7a and the return pipe line 7b in the middle of the pipe lines; a three-way valve 11 diverging hot water within the return pipe line 7b to the water supply tank 6 side and the branch pipe line 12 side; and a controller 14 controlling the three-way valve 11 based on detection output by a water temperature sensor 13 for detecting water temperature on the downstream side from a connection part of the going pipe line 7a with the branch pipe line 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
