電気伝導度測定センサー７と、これらに接続した
制御部８を具備することにより、上記センサーで
検出する缶水の電気伝導度が規定値を超えたとき
に、該センサーからの信号により前記制御部を介
して前記濃縮ブロー弁を開弁し、ブロー作動せし
めるごとく動作する自動ブロー装置Ｃの構成にお
いて、前記制御部に、ブロー作動の信号を発する
と同時に計時作動し、設定時間を経過すると警報
を発する計時判別部９を併せ設けてなることを特
徴とする濃縮ブロー系統異常検出装置。 By providing a concentrating blow valve 4 and an electrical conductivity measurement sensor 7 applied to the canned water of the boiler 1, and a control unit 8 connected to these, the electrical conductivity of the canned water detected by the above sensor exceeds a specified value. In the configuration of the automatic blow device C, which operates as if the concentration blow valve is opened and the blow operation is performed via the control section in response to a signal from the sensor, a signal for blow operation is sent to the control section. This concentration blow system abnormality detection device is characterized in that it is also provided with a timing determination section 9 which operates to measure the time at the same time as the set time has elapsed and issues an alarm when the set time has elapsed.
