Flame lift-off in oil fired pressure jet burners is an unwanted condition in which the flame and burner become separated. This condition is most commonly created by excessive combustion air and often results in the loss of flame as the photo-electric cell fails to register the light of the flame, this in turn results in a safety lockout of the control box. ==Other outcomes== Other outcomes may be experienced: – # There may be delayed ignition as the oil spray is too far forward for the electrodes to ignite, only when the oil spray has filled the combustion chamber will the mixture ignite. In this condition it is likely that the excessive volume of unburnt oil will ignite with explosive ignition. # The oil mixture will fail to ignite resulting in safety lockout of the control box. # The oil mixture will ignite but may burn very inefficiently due to excessive air chilling of the oil particles to the point where complete combustion of the oil is not possible. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Flame lift-off」の詳細全文を読む スポンサード リンク
