Gas boiler control method that operates regardless of the wind

摘要

The present invention relates to a control method of a gas boiler. More specifically, since the burning operation is performed in the burner irrespective of the presence of the backward flow from the outside through the exhaust communication which is the passage for discharging the combustion gas in the gas boiler of the forced exhaust mode or the forced air supply and exhaust mode, The present invention relates to a gas boiler control method that operates stably and operates irrespective of the adverse wind that blocks the inflow of waste gas by a backward wind.;A control method of the present invention is characterized by providing a natural exhaust fan that rotates only in one direction so as to prevent exhaust gas from flowing from the outside to the outer side end portion of the exhaust communication, And the control microcomputer compares the measured value with a control signal to output the control signal so as to change the number of revolutions of the exhaust fan in accordance with the compared number of revolutions.
