As shown in Figure 1, the generator 122A entering into absorption heat pump 122 from the water of the higher temperature (such as 100 DEG C) of flue gas generation device 110 by first liquid flow pipe 140A drives absorption heat pump 122.Low-temperature receiver medium (such as the water of 40 DEG C) enters into the condenser 122C of absorption heat pump 122 by the first low-temperature receiver medium circulation tube road 150A.In absorption heat pump 122, water in generator 122A can carry out heat exchange with the low-temperature receiver medium in condenser 122C and make the temperature of the water in generator 122A tentatively be reduced to such as 80 DEG C, and the temperature of low-temperature receiver medium in condenser 122C is tentatively increased to such as 45 DEG C.
Water after generator 122A tentatively lowers the temperature is transported in plate type heat exchanger 121 after being pressurizeed by force (forcing) pump 180 in second liquid flow pipe 140B, and carry out further heat exchange with the low-temperature receiver medium come in condenser 122C, make the temperature of the water be passed to the 3rd liquid communication pipeline 140C from plate type heat exchanger 121 can be reduced to such as 55 DEG C further, the temperature of the low-temperature receiver medium in condenser 122C is tentatively increased to such as 65 DEG C.
