供給停止等の措置を講じている。2. Description of the Related Art A gas turbine applied to a power plant is driven by a combustion gas by burning a mixture of air and fuel compressed by a compressor in a combustor. Ignition in a combustor of a gas turbine is performed by an ignition plug, and the combustor is provided with a flame detection device that detects a flame by ultraviolet rays. An ignition state (misfire state) is detected by a flame detection device, and if a misfire occurs, measures such as stopping supply of fuel are taken.

が着火されたかを判断している。In a conventional flame detecting device, a glass tube facing a combustion chamber is installed in a main body of a combustor, and a UV photoelectric tube is attached to an end of the glass tube. The UV photoelectric tube detects whether there is a short wavelength ultraviolet ray unique to the flame in the combustion chamber, and determines whether the combustor is ignited.

の作業が必要となっていた。Since the combustor of a gas turbine is at a high temperature (for example, 1500 ° C.), the temperature of the combustor is increased through a glass tube.
Even if the UV phototube is attached, the UV phototube is exposed to a high-temperature environment and is a place where vibration occurs. For this reason, conventionally, a special UV photoelectric tube capable of coping with vibration and high temperature was used, or a water-cooling device was added, so that the cost was high and the device was complicated. In addition, when maintenance such as replacement of the UV photoelectric tube is performed, work such as replacement of ancillary equipment such as water cooling equipment has been required.

Since the upper combustor is ignited, the flame detection device is mounted on the upper combustor which is ignited last. For this reason, the operation was performed at a high place, and the operation was stopped.

なってしまう。It is conceivable to use an optical fiber to guide ultraviolet light to a place away from the combustor, and to detect the ultraviolet light guided by the optical fiber with a UV photoelectric tube. However, the optical fiber is easily broken and bent into a curved state. It is difficult to guide to the place, and the optical fiber transmitting the ultraviolet light is special and expensive.
