Abstract
PURPOSE: To enable a smooth fuel supply by a method wherein an output frequency proportional to an input voltage is generated for conducting combustion control when a high temperature is to be kept constant, and pulse width is reduced according to the input voltage without lowering frequency when a low temperature is to be kept constant.
CONSTITUTION: A temperature sensor 8 detects the temperature inside of a drying chamber 9. In the case of a set error for maintaining a high temperature, a voltage- to-frequency converter 3 for generating a frequency proportional to an input voltage is operated by a discriminator 10 to generate a pulse signal, which is fed to a pulse width regulator 11. The output signal from the regulator 11 is amplified by a pulse amplifier 5, before driving an electromagnetic pump 6. In the case of a set error for maintaining a low temperature, the discriminator 10 causes the converter 3 to generate a constant frequency irrespective of the magnitude of the input voltage, and the regulator 11 generates a pulse width proportional to the input voltage. Temperature setting is performed by a setter 1, of which the output is impressed on the converter 3 and discriminator 10 through an error amplifier 2.
