Abstract
A method for preventing coagulation in an exhaust pipe of a boiler is provided. The method includes proportionally controlling combustion based on a quantity of supplied fuel with respect to an amount of air supplied to a burner, determining whether to enhance a heating power of a burner, based on a temperature of ambient air introduced into a blower, the temperature of the ambient air being sensed by an air temperature sensor, and enhancing the heating power of the burner to increase a temperature of exhaust gas, when it is determined that the sensed temperature is equal to or lower than a predetermined temperature.
Claims4
A method for preventing coagulation in an exhaust pipe of a boiler, the method comprising:
- controlling combustion proportionally based on a quantity of supplied fuel with respect to an amount of air supplied to a burner;
- determining whether to enhance a heating power of a burner, based on a temperature of ambient air introduced into a blower, the temperature of the ambient air being sensed by an air temperature sensor;
- and
- enhancing the heating power of the burner to increase a temperature of exhaust gas, when it is determined that the sensed temperature is equal to or lower than a predetermined temperature,
- wherein the determining whether to enhance the heating power of the burner comprises determining if the burner has been operated during a predetermined time interval while consuming a predetermined quantity of fuel.
