Anti fuel oil self combustion point detector for power plant

The utility model provides an anti fuel oil self combustion point detector for power plant, comprising a heating furnace, a signal collector and a signal processor. The utility model is characterized in that a signal collection circuit comprises an oscillator, a drive module, a transformer, a sensor, a rectification filtering module, an amplifying module and a comparative module, wherein, the oscillator is connected with a primary coil of the transformer via the drive module, a secondary coil of the transformer is connected with the sensor, a detection signal exported by the sensor is exported to the comparative module after being processed via the rectification filtering module and the amplifying module, and the detection signal is exported to the signal processor by the comparative module, and the detection result is received after analysis. An anti fuel oil self combustion point in the heating furnace is collected by the signal collector and exported to the signal process for analyzing process, finally the self combustion point of a detected sample is received, so the detector overcomes the defects that a reflector is used for manually observing in the past, and harmful gas causes damages to human body, and has the advantages of simple and reasonable structure and high precision.
