<P>PROBLEM TO BE SOLVED: To provide a condensed water treatment device, wherein when abnormality occurs on a check valve provided in a discharge passage for condensed water, the fact can be exactly perceived. <P>SOLUTION: The condensed water treatment device A is equipped with: a vessel 2 where the condensed water generated accompanying heat recovery is received from a combustion apparatus B, so as to be stored; a pump P which starts driving when the amount of the condensed water stored in the vessel 2 reaches the fixed one, and discharges a prescribed amount of the condensed water to the outside of the vessel; and a check valve 79 provided at the discharge passage 75 for the condensed water. The device performs: a treatment where the estimated driving frequency of the pump P is calculated correspondingly to the driving of a combustor 91; a treatment where the actual driving frequency of the pump P is counted; and an abnormality distinction treatment including a treatment of comparing the count number with standard frequency for abnormality distinction decided based on the estimated driving frequency, and is also provided with a judgement means 6, when the count number exceeds the standard frequency for abnormality distinction, which judges that the stop valve 7 is abnormal. <P>COPYRIGHT: (C)2007,JPO&INPIT |
