制御装置。 A thermistor 9 and a resistor 10 for detecting the temperature of the vaporizing section in a device that preheats and vaporizes fuel oil in a vaporizing section and burns it in an oil combustor via a control section.
A voltage comparator 11 that applies the voltage at the connection point between the resistors 7 and 8 to the input end 11a and the voltage at the connection point between the resistors 7 and 8 to the other input end 11b, and the voltage applied to both input ends 11a and 11b. and a microcomputer 12 that inputs the output signal of the voltage comparator 11 that changes depending on the conditions, and the output signal of the voltage comparator 11 before the start of preheating and immediately before transition to normal combustion and the input terminals 11a and 11b. A short detection section 12a detects the short state of the thermistor 9 from the applied voltage, an open detection section 12b detects the open state of the thermistor 9, and a partial pressure between the thermistor 9 and the resistor 10 and the resistors 7 and 8 during combustion. The microcomputer 12 is provided with a vaporizing section abnormality detecting section 12c that detects an abnormality in the vaporizing section through the output voltage of the voltage comparator 11 to which the voltage is respectively input, and furthermore, these detecting sections 12a, 12b, 12c are provided.
1. A vaporizing section temperature control device for an oil combustor, characterized in that a microcomputer 12 is provided with a control section 13 that controls combustion of the oil combustor by inputting an output signal from the combustor.
