摘要： PURPOSE:To perform a positive ignition and maintain a safety when an ignition failure occurs, by a method wherein, after ignition of a burner, an electromagnetic valve is opened by a DC power source within a time for which a thermocouple generates a sufficient electromotive force by the use of heat. CONSTITUTION:After several seconds have elapsed after closed, a gas igniter 3 is energized through a timer switch 2 for releasing. Through the working of the timer switch 2, an electromagnetic coil 6 for an electromagnetic valve 5 located in a gas feed path is energized through a diode 4. The gas igniter 3 is provided with a discharge electrode 7 and is positioned so as to ignite a burner 8. A thermocouple 9 is connected in parallel to said electromagnetic coil 6, the thermocouple being located in the vicinity of the burner so as to be subject to the heat generated by the burner 8. Further, a heat-sensitive resistance 10 having a negative temperature coefficient is inserted into a circuit for the thermocouple 9, the resistance 10 being placed in a position where the resistance is subject to the heat produced by the burner 8. This enables to perform a reliable ignition and maintain safety when an ignition failure occurs through a simple ignition operation even during the use of the thermocouple.

摘要： PURPOSE:To facilitate the connection, by providing a plurality of optical fibers successively in the direction of transmitting light while the diameter of the optical fibers is differentiated. CONSTITUTION:Optical fibers used for a flame monitor are provided in the plurality of optical fibers 10-12 in the direction of transmitting light and differentiated in the diameter. In other words, a light admitting optical fiber 10 mounted on a light admitting head has the largest outer diameter, for example, about 800mum in the outer diameter of a clad 10b formed in the perimeter of a core 10a. Then, a relay optical fiber 11 housed in an outer cylinder composing a monitor body shall be, for example, about 500mum in the outer diameter of a clad 11b. Then, an optical fiber 12 of the smallest diameter is connected to the relay optical fiber 11 and is made even smaller than the relay optical fiber 11. With such an arrangement, only damaged ones can be exchanged even when a damage takes place in a part of the optical fibers used, making the apparatus economical while facilitating the connection of the optical fibers.

摘要： 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.

摘要： PURPOSE:To detect the presence of flame accurately, by computing flame characteristic from signals of light detected to compute the characteristic value in comparison with the flame characteristic memorized. CONSTITUTION:A light signal of a flame detected with a flame detector head 4 is converted into a digital signal through a preamplifier 15 and an A/D converter 6 and inputted into a Fourier converter 7 to be converted to the level for each frequency, the signal of which is inputted into a smoothing device 8 and a characteristic value computing section 9. With the computing section 9, the characteristic of a burner flame to be predetected is computed to calculate the flame characteristics with flame and without flame, where are memorized into a memory section 10.
