Abstract (en)
A gas burner arrangement comprises a gas burner in which spark-gaps 20 are defined between a plurality of flame electrodes 15 supported by a cover plate 7 and opposing electrode 5, a spark generator 31 and a flame failure sensor 32. The sensor 32 senses the absence of flame only when there is an absence of flame extending from each flame electrode 15 to the opposing electrode 5 at the same time and, in response to such absence of flame, initiates energisation of the spark generator to effect sparking and reignition of the burner. The arrangement reduces the likelihood of so-called "nuisance" sparking which has been found to occur where a single sparking electrode is employed and the flame, without being extinguished, moves away from the sparking electrode. <IMAGE>
