PURPOSE: A method for preventing dew condensation in a combustion chamber of a condensing boiler is provided to prevent ignition fail by preventing the clogging of the hole of boiler nozzle part by dew condensation. CONSTITUTION: A method for preventing dew condensation in a combustion chamber of a condensing boiler is as follows. If it has combustion demand, an igniter operates, and detection of flame is determined(S1,S2,S3). If flame is detected, the combustion is performed(S4) It continuously judges whether fire extinguishment is required or not(S5). If the fire-extinguishing demand is inputted, it determines whether the temperature of external air is higher than a fixed temperature(A°C)(S6,S7). If the temperature of outside is higher than the fixed temperature, a blowing fan rotates in predetermined revolution speed for a predetermined time(S8,S9). |
