<P>PROBLEM TO BE SOLVED: To provide a cogeneration system capable of immediately performing the heat exchange in restarting a power generating device by preheating the power generating device in advance before restarting the power generating device. <P>SOLUTION: This cogeneration system comprises the power generating device 2, a heat exchanging part 32, a hot water storage tank 31, a temperature sensor 37 and a control part 8, and the temperature sensor 38 detects a temperature of supplied hot water at a specific position in the hot water storage tank 31. When the power generating device 2 generates the power, the supplied hot water circulated between the hot water storage tank 31 and the heat exchanger 32 is heated by the heat exchanger and stored in the hot water storage tank 31. When the power generating device 2 is in a stopped state, and the temperature detected by the temperature sensor 38 reaches the predetermined preheating starting temperature, the control part 8 starts the preheating of the power generating device 2 to achieve a preheating completion state. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
