AIR PROPORTIONAL CONTROL TYPE COMBUSTION DEVICE AND METHOD FOR ADJUSTING HEAT AMOUNT THEREOF

摘要

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 number of revolutions of a blower, is capable of compensating for an air flow speed with respect to external circumstances such as place of installation, blocking of a gas duct, and seasonal changes, or the number of revolutions of the blower caused by such situational changes. In a case where there is a difference between wind pressure (Act.APS) measured after the blower is driven at a reference number of revolutions (Ref.RPM) in a state where gas supply is blocked and reference wind pressure (Ref.RPM), the combustion device compensates for the difference while causing the number of revolutions to vary and applies the varied number of revolutions as a new reference number of revolutions.
