Claims (1)
位Ｂを表わす下限水位検出器２を設け、水位が上
限水位Ａにあるときに燃焼を開始するボイラー３
において、ボイラー起動時にボイラーの水位が上
限水位検出位置Ａに達してから設定時間Ｔ０内に
、下限水位検出器２から下限水位Ｂ検出不能信号
を受信すればブロー装置誤操作信号を出力する機
能を備えた判別器４を設けたことを特徴とするブ
ロー装置の誤操作検出器。 A boiler 3 is provided with an upper limit water level detector 1 representing an upper limit water level A and a lower limit water level detector 2 representing a lower limit water level B, and starts combustion when the water level is at the upper limit water level A.
, if the lower limit water level B cannot be detected signal is received from the lower limit water level detector 2 within a set time T0 after the water level of the boiler reaches the upper limit water level detection position A at the time of starting the boiler, a function is provided to output a blow device erroneous operation signal. An erroneous operation detector for a blow device, characterized in that a discriminator 4 is provided.
