Variable length adjustable flame scanner
First Claim
1. An apparatus for varying a length of a flame scanner assembly for monitoring a flame, comprising:
- 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,wherein 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.

Abstract
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.

10. A flame scanner for monitoring a flame in a boiler, comprising:
-
a head assembly containing electronic components; a lens assembly including a lens; a fiber optic cable extending between the lens and the electronic components; a spool assembly having a chamber disposed therein, the chamber receiving a portion of the fiber optic cable; a sleeve disposed around the fiber optic cable and extending between the lens assembly and the spool assembly; and a mounting shaft disposed between the sleeve and the spool assembly; wherein a length of the flame scanner is adjusted via telescopic interconnection between the spool assembly and the mounting shaft such that longitudinal displacement therebetween may be varied by slidable displacement of the mounting shaft relative to the spool assembly. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method to vary a length of a flame scanner assembly to match a length of a guide pipe in which the flame scanner is installed for monitoring a flame, the method comprising:
-
disposing one end of a mounting shaft in a barrel defining one end of a spool assembly; slidably displacing the mounting shaft relative to the spool assembly to adjust a length of the flame scanner in a telescopic manner; and extending a mechanical fastener through the one end of the spool assembly to the mounting shaft to prevent further slidable displacement of the mounting shaft relative to the spool assembly and fix a longitudinal displacement therebetween. - View Dependent Claims (20)
