A flame scanner includes a lens barrel assembly defining a generally hollow body having a first end and a second end, and an opening formed in the first end, a lens positioned adjacent to the second end, and a fiber optic cable receivable through the opening in the first end, the fiber optic cable having a distal end. A field of view of the flame scanner is selectively adjustable by varying a position of the distal end of the fiber optic cable with respect to the lens.

System, method and apparatus for adjusting a flame scanner

An ignitor spark indicatoris described that monitors RF signals within a flame rodlocated near a spark rod. The signal from the flame rodis processed to provide a waveform that indicates when electrical arcing is occurring. The indication when arcing is occurring is also provided to flame-detecting equipment. The flame-proving deviceonly operates when the arcing is not produced so that the flame-detecting devicedoes not confuse the arcing with a flame reducing the false positive determinations.

Ignitor spark status indicator

A flame scanner collimator, which monitors flames produced by a fossil fuel fired combustion chamber, includes: a substantially cylindrical collimator body defining a hollow portion; a first chamber connected to a second chamber, the first and second chambers defining the hollow portion, the second chamber having a larger diameter than the first chamber; and a plurality of slots each extending in substantially a same direction as a longitudinal axis defining the body. Each slot extends through the body to the first and second chambers to allow cooling/purge air flow therethrough.

Flame scanner collimator body

An apparatus for varying a length of a flame scanner assembly for monitoring a flame includes a mounting shaft which connects to a fiber optic cable assembly; and a spool assembly having a first end and a second opposite end. The first end connects to a detector head assembly and the second end is configured to connect to a guide pipe. The second end of the spool assembly receives one end of the mounting shaft and a length of the flame scanner assembly is adjusted via telescopic interconnection between the second end of the spool assembly and the one end of the mounting shaft such that longitudinal displacement therebetween may be varied by slidable displacement of the mounting shaft relative to the spool assembly.
