PROBLEM TO BE SOLVED: To provide a flame detection system utilizing a reusable sensing fluid. SOLUTION: The flame detection system 10 includes a detection tube 22 and a valve 16. The detection tube 22 contains the sensing fluid 23 having a first physical condition and a second physical condition. The sensing fluid 23 is, in the first physical condition, lower than a threshold temperature, and is, in the second physical condition, higher the threshold temperature. The sensing fluid 23 is, at least partially, liquid in the first physical condition. A detection device is set to open, in response to a transition of a portion of the sensing fluid 23 from the first physical condition to the second physical condition. A cylinder 12 containing a flame suppressant 13 is operable to distribute the flame suppressant 13 through a distribution tube 14 via the release valve 16. The distribution tube 14 has a nozzle 18, and through the nozzle, the flame suppressant 13 is emitted. The release valve 16 keeps a closed state, until being opened by a release valve actuation assembly 20. COPYRIGHT: (C)2011,JPO&INPIT
