Abstract
PURPOSE: To improve response and precision by comparing the detection signal wave form of a hot-water supply temperature with a specified reference wave and changing the ON and OFF durations in a specified period of the reference wave thereby to control a gas valve.
CONSTITUTION: In a flash water boiler, the combustion heat of a main burner 5 is given to the water fed from a feed water pipe 2 in a heat exchanger 1, and the resulting hot water is supplied through a hot-water supply pipe 3. A temperature detector 15 detects the hot-water supply temperature on the downstream side of the heat exchanger 1 and generates an electrical output indicating the temperature change, and the output is changed by a converter 16 before fed to an electric-valve driving circuit 17. The conver 16 consists of a resistance-to-voltage converter 18, reference wave generator 19, control signal generator 20, and drive signal generator 21. When the hot-water supply temperature has fallen below a setpoint, the electric- valve ON duration in a predetermined period is prolonged to increase the gas amount, thereby raising the temperature. On the other hand, when the hot-water supply temperature has risen above the setpoint, the electric-valve OFF duration is prolonged to lower the temperature.
