Controlling device of combustion air

Abstract

Abstract PURPOSE:To improve thermal efficiency, as of a hot-water supplyer, etc. by bypassing part of the constant stream of forced air supply and exhaust gas so that the air fuel ratio may remain constant despite variations in combustion rate and that a stable balance may be maintained between air supply and exhaust gas against a disturbing wind. CONSTITUTION:A fan 1 supplies a hot-water supplyer A with a constant flow of combustion air from an air inlet 3 and lets exhaust gas out of an exhaust port 9. With variations in combustion rate, a driving motor 15 adjusts the opening degree of an adjustable damper 16 which is loaded with a spring 17 so that the air supply is mixed with the exhaust gas and absorbed via the fan 1 to be discharged. With the fan 1 revolving at a constant speed, the damper 16 is opened to feed surplus air into the exhaust gas so that the air flow to be supplied to a burner 4 may have a constant air fuel ratio.
