Abstract

PURPOSE: To bring temperature in a heating drying furnace close to set value most faithfully by a method wherein the amount of discharge of an electromagnetic pump is controlled by stages and in high accuracy in response to responding time for which a temperature sensing element detects the temperature in the heating drying furnace, and supplied to a burner.
CONSTITUTION: Voltage V1 by a thermistor 10 for detecting temperature mounted into a heating drying furnace and voltage V2 by a resistor 11 for setting temperature are compared by means of a comparator 12, and signals at a low level or a high level are output. An input terminal Ci of an up counter 14 is wired to an oscillator 15 outputting pulses at a fixed oscillating period. The output terminals C01WC04 of the up-down counter 14 are each wired to a ladder-type circuit 16. Output voltage of sixteen kinds is generated at an output terminal Lo of the ladder-type circuit 16 in response to output signals output at a BCD code from the up-down counter 14. The voltage is converted into frequency, and inputted to a base of a transistor TR driving an exciting coil L of an electromagnetic pump.
