Title: Burner control arrangement - has flame detector-operated electromagnet with intermediary links creating safe gap between sensitivities
Inventor: BERNER WALTER
IPC: F23N5/08
Filed: 1975-04-18
Abstract: The burner control design aims to eliminate the possibility of a burner malfunction in case the detector is exposed to freak light or the detector itself is faulty. The present arrangement provides means to create a sufficient sensitivity gap between the testing and operation conditions and, in addition, the switch-over arrangement from testing to operation conditions contains elements which block the fuel supply, if the detector is faulty. The function of these elements is independent from the electrical circuit. When the bimetal element (1) is heated consequent upon a start demand the link (12) prevents the attracted armature (10) from switching over the contact springs (4, 5).
