Combustion control system for burner |
摘要 |
A combustion control system for a burner having an analog circuit unit which includes a photosensor for detecting combustion flame of the burner, an amplifier for amplifying a detection output from the photosensor, a rectifier for rectifying the amplified signal to a DC component, and an integrator for smoothing the rectified signal to obtain an oscillating power signal. The control system further has a potentiometer for generating an output voltage corresponding to a degree of opening of a fuel flow control valve of the burner, a digital circuit unit supplied with an output signal from the potentiometer and an output signal from the integrator to compare these signals with a plurality of preset combustion state reference values and to output a normal combustion state signal, an incomplete combustion state signal or a flame failure signal in accordance with the result of the comparison, and a controller for outputting either a burner combustion maintaining signal or a burner combustion suspending signal on the basis of the output signal from the digital circuit unit.
