Abstract
The present invention provides a combustion device. In ON-OFF combustion control processing for intermittently performing the combustion operation of burners (4), a control unit (30) of a combustion device (water heater) (1), which includes the burners (4), a fuel supply unit (5), and a combustion fan (10), controls the fuel supply unit (5) and the combustion fan (10) so as to change the amount of a fuel to be supplied to the burners (4) and the number of rotations of the combustion fan (10) according to a required amount of heat for the temperature control of a target fluid (water for hot water supply) when the burners (4) are ignited to restart a combustion operation after the burners (4) are extinguished.
Claims6
A combustion device comprising:
- a burner which generates heat for heating a target fluid by a combustion operation;
- a fuel supply unit which supplies a fuel to the burner;
- a combustion fan which supplies air for combustion to the burner;
- and a control unit which has a function for determining a required amount of heat for temperature control of the target fluid and for controlling the fuel supply unit and the combustion fan according to the required amount of heat,
- wherein the control unit is configured to be capable of performing ON-OFF combustion control processing, which is processing for controlling the fuel supply unit and the combustion fan so as to intermittently perform the combustion operation of the burner, and is also configured to control the fuel supply unit and the combustion fan so as to change an amount of a fuel to be supplied to the burner and a number of rotations of the combustion fan according to the required amount of heat for temperature control of the target fluid at the time of igniting the burner to restart the combustion operation of the burner after the burner is extinguished in the ON-OFF combustion control processing.
