Abstract

PURPOSE: To restrict an overshoot to be caused at a rapid decrease of water supply amount by the additional provision of an overshoot judging circuit in a proportional control system included in the combustion control device of the proportional control system which carries out the control based on the temperature of water.
CONSTITUTION: In the combustion control device of the proportional control system including a water temperature detector which provide a signal representing the detected value, a PID control circuit which includes a common integrating circuit comprising an OA amplifier 41 and the like and receives the signal from the detector, and a fuel supply means which determines the amount of fuel supply based on the output from the PID control circuit and supplies the fuel accordingly, a circuit for detecting an overshoot occurrence of the water temperature is provided which fanctions in accordance with the water temperature detection signal. In such a construction, if the water supply rate Wo rapidly decreases to W2, a thermister 6 detects this decrease after a short period, And when the detected value exceeds an overshoot judging temperature, the overshoot judging circuit reverses to compulsively make an unreversible input of the OA amplifier 41 to be of a low level. Accordingly, the current flowing through a proportional valve 3 is decreased to such a value as to allow the amount of gas at the necessary minimum.
