    • PROBLEM TO BE SOLVED: To provide a flame monitoring device for detecting flame and accurately analyzing a combustion state of the flame.
      SOLUTION: The flame monitoring device for observing infrared rays of prescribed wavelength regions radiated from the flame to detect the flame includes: a Fourier transform means for obtaining fluctuation frequency components of infrared ray signal intensity in the prescribed wavelength regions; and a determining means for determining size of the flame on the basis of frequency distribution of spectral intensity exceeding a prescribed threshold. The device determines the size of the flame by spectrally analyzing components of fluctuation of the flame corresponding to the size of the flame.

    • PURPOSE:To obtain a lighting head suitable for a flame monitor apparatus by providing optical fiber receiving parts allowed to be formed and positioned at different angles and the optical fiber communication part communicated with said receiving parts to the leading end part of a main body. CONSTITUTION:In the lighting head of a flame monitor apparatus using an optical fiber, grooves 10a, 10b, 10c for receiving the leading end parts of optical fibers are formed at different mount angles. The optical fibers 4a, 4b, 4c are received in and arranged to said grooves and a plurality of visual fields are obtained as a whole of the apparatus by differentiating the mount angles of the optical fibers 4. The optical fibers 4 themselves reach a connector 7 through a communication groove 11 and arranged in the main body of a monitor apparatus. Because all of the optical fiber receiving parts are formed as grooves and the one end of the lighting head forms an open space, said optical fibers are directly exposed to cooling air and, therefore, cooling efficiency becomes high.
    • 目的:通过提供允许形成和定位在不同角度的光纤接收部分和与所述接收部分连通的光纤通信部分到主体的前端部分,获得适用于火焰监测装置的照明头。 构成:在使用光纤的火焰监视装置的照明头中,以不同的安装角度形成用于容纳光纤的前端部的槽10a,10b,10c。 光纤4a,4b,4c被接收并布置在所述槽中,通过区分光纤4的安装角度,整个设备获得多个视场。光纤4本身到达连接器7 通过连通槽11布置在监视器装置的主体中。 因为所有的光纤接收部分形成为沟槽,并且照明头的一端形成开放空间,所以光纤直接暴露于冷却空气,因此冷却效率变高。
