Abstract

PURPOSE:To facilitate signal processing, prevent relay operation and raise the safety in the trouble of electrode or transistor in a flame rod detection system, by making it possible to improve the SN ratio and performing the detection through AC operation. CONSTITUTION:When n (number) ions of e coulomb in charge move at a speed of v m/s, a physical phenomenon corresponding to an electrical current of I amperes takes place. If a magnetic field with a magnetic flux density of B weber/m<2> is applied perpendicularly to the movement of the ions, the ions are deflected by a force F=IXB (vectorial outer-product). To utilize this principle, magnetic force line generators (for instance, permanent magnets) 7 are provided in the face of each other across the flame 2. Voltage detecting electrodes 3, 4 are provided centering the flame so that the electrodes are located on the plane perpendicular to the generators. A detection signal is supplied from the electrodes to a controller 6 through an amplifier 5.
