摘要：A gas-fired appliance includes a tank configured to store a fluid to be heated, apowered anode extending into the tank and configured to generate an electric anodecurrent, and a combustion chamber including a burner configured to generate productsof combustion. The appliance also includes an exhaust structure, a heat exchanger, and anelectronic processor coupled to the powered anode. The products of combustion flowfrom the combustion chamber to the exhaust structure via the heat exchanger. Theelectronic processor is configured to determine a duty cycle of the burner, determinewhether the duty cycle of the burner exceeds a predetermined threshold, increase amagnitude of a protection parameter of the powered anode from a first value to asecond value when the duty cycle of the burner exceeds the predetermined threshold,and control the powered anode according to the second value of the protectionparameter.
