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.

Variable length adjustable flame scanner

An ionic flame monitor. The flame monitor has a flame rod that produces an ionization current when the flame rod is immersed in a flame and excited by a voltage. The ionization current has a DC component and an AC component each dependent on the intensity of the flame, and a flicker frequency. The flame monitor also has a computing device that is responsive to signals representative of the flicker frequency, and the AC and DC components of the ionization current for determining the existence of the flame.
