  • Publication number: 20150345787
    Abstract: Disclosed are an air proportional control type combustion device and a method for adjusting the heat amount thereof. The combustion device according to the present invention, which controls the output heat amount by controlling the RPM of a blower, is capable of compensating for an air flow rate with respect to external circumstances such as place of installation, blocking of a gas duct, and seasonal changes, or the RPM of the blower caused by such situational changes. In a case where there is a difference between air pressure (Act. APS) measured after the blower is driven at a reference RPM (Ref. RPM) in a state where gas supply is blocked and reference air pressure (Ref. RPM), the combustion device compensates for the difference while causing the RPM to vary and applies the varied RPM as a new reference RPM.
