COMBUSTION MONITOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a compact combustion monitor device which appropriately detects the combustion and vibration condition of a combustion device to obtain the stable combustion condition. SOLUTION: A fluctuation of emission in a flame surface in a combustion device 1 is detected by an optical probe 14, and the optical signal of the fluctuation of emission detected by the optical probe 14 is converted to the electric signal by a photoelectric converting element 15. The electric signal converted by the photoelectric converting element 15 is amplified by an amplifier 16, and the electric signal of the fluctuation of emission amplified by the amplifier 16 is input to a combustion and vibration condition analyzer 16. The combustion and vibration condition analyzer 17 obtains the dominant frequency and a fluctuation level by analyzing frequency, and obtains the combustion and vibration condition on the basis of the dominant frequency and the fluctuation level. The combustion and vibration condition is monitored thereby. COPYRIGHT: (C)2004,JPO
