  • Publication number: 20220026066
    Abstract: A combustion apparatus includes a combustion part, a blower fan, an ignition device, and a control part. The control part selectively performs continuous combustion in which the combustion part is operated to burn continuously and intermittent combustion in which a combustion period and a non-combustion period of the combustion part are repeatedly provided. When the continuous combustion is stopped, the control part extinguishes the combustion part and operates the blower fan to perform a scavenging operation. When the combustion period in the intermittent combustion is ended, the control part extinguishes the combustion part and operates the blower fan to perform a scavenging operation in the non-combustion period. A total air blowing amount of the blower fan in the scavenging operation during the non-combustion period is set to be less than a total air blowing amount of the blower fan in the scavenging operation when the continuous combustion is stopped.
