PURPOSE:To improve waste heat recovering efficiency in case of recovering as electric power the waste heat of exhaust gas of medium and low temperature by means of fron turbine equipment, by turning water of low temperature into water of high temperature through sending it to an exhaust sensible heat recovery equipment and varporizing Fron liquid by the water of high temperature. CONSTITUTION:Water of low temperature, raised in its temperature in a convertor exhaust cooler 12 of a convertor exhaust cooling equipment 10, is stored in a warm water tank 13 and then sent into a heat exchanger 34 of a sensible heat recovering equipment 30 for sintering machine exhaust by means of a pump 23. Here, the sensible heat of the sintering machine exhaust is recovered as water of high temperature, which is supplied to a Fron vaporizer 41 of a Fron turbine generating equipment 40 through a piping 38. Further. Fron gas produced through heat exchange between water of high temperature and fron liquid is supplied to a fron turbine 42 through a Fron gas pipe 47 to drive a generator 43 into its rotation. Warm water sent out from the evaporizer 41 is returned to the convertor exhaust cooling equipment 10 through a Fron preheater 46 and a return pipe 51. |
