    • A flame management system comprises two flame detector units which are arranged to view different regions of at least one flame and are connected to separate channels of a processor. Each detector unit has at least two operating modes, such as an infra-red and an ultra-violet operating mode, or a normal and a sensitive infra-red or ultra-violet mode, etc. and is switchable between those modes by the processor. The processor thus selectively processes the output of the two units and actively controls the operating mode of each to obtain responses appropriate to the type and/or condition of the or each flame being monitored. In order to enable both IR and UV monitoring from a single detector unit, the detector includes at least one photo-sensitive member together with an optical element such as an IR filter which operates selectively to deliver an undivided IR or an undivided UV compact to the at least one photo-sensitive member.
    • 火焰管理系统包括两个火焰检测器单元,其被布置成观察至少一个火焰的不同区域并连接到处理器的分离通道。 每个检测器单元具有至少两种操作模式,例如红外和紫外线操作模式,或正常和敏感的红外或紫外线模式等,并且可由处理器在这些模式之间切换 。 因此,处理器选择性地处理两个单元的输出并且主动地控制每个单元的操作模式以获得适合于被监视的或每个被监视的火焰的类型和/或状况的响应。 为了实现来自单个检测器单元的IR和UV监测,检测器包括至少一个光敏元件以及诸如IR滤光器的光学元件,该IR滤光器选择性地将未分离的IR或不分割的UV致密物输送到 至少一个感光元件。
