Claims (1)
を用いている燃焼制御装置において、燃焼時間が
連続して長時間になる場合、燃焼安全制御装置に
おいて、自動的に燃焼を停止させて、一定時間後
再燃焼させ、燃焼時と燃焼停止時のＵＶセルの計
測値を比較することにより、ＵＶセルの劣化を検
知する機能を有するボイラの燃焼安全制御装置。 In a combustion control device that uses a UV (ultravision) cell as a flame detection device, if the combustion time continues for a long time, the combustion safety control device automatically stops combustion and restarts it after a certain period of time. A combustion safety control device for a boiler that has a function of detecting deterioration of a UV cell by reburning it and comparing the measured values of the UV cell during combustion and when combustion is stopped.
