<p>PURPOSE:To improve a thermal recovery efficiency and make a compact recovery device by a method wherein a waste heat of low temperature is guided to a vacuum steam generating device, steam got by the vacuum stem generating device is guided into a heat exchanger and then hot water is attained. CONSTITUTION:A discharged gas G' of a gas turbine 11 is guided into a discharged gas boiler 13. The discharged gas G' and fed water W are heat exchanged there and then the heat is recovered as a high pressure steam S. AS a result of thermal recovery at the discharged gas boiler 13, the discharging gas G'' of relatively low temperature is guided to a vacuum steam generating device 14, thereby the heat is recovered and then the gas is discharged into the surrounding air as the discharging gas Ge. Steam S' of low temperature and low pressure got by the vacuum steam generating device 14 is guided to the heat exchanger 15 by a line l3 heat exchanged with supplied water W supplied by a line l4 so as to get a hot water (h).</p> |
