Heating operation control method during the early digestion under heating operation the boiler

摘要

The present invention relates to a control method of heating operation during early fire extinguishing during heating operation of a boiler. In addition, the present invention comprises the following steps: operating a circulation pump; performing heating combustion; performing control of a heating value; determining whether or not a heat supply set temperature (Tout) is higher than or equal to a value obtained by multiplying a heat supply set temperature (Tset) by a first multiple (T1); determining whether or not a value obtained by subtracting the heat supply set temperature (Tset) by a heating return temperature (Tin) is lower than or equal to a predetermined temperature difference (ΔT) for a first predetermined time (A) or longer; determining whether or not the heat supply temperature (Tout) is higher than or equal to a value obtained by multiplying the heat supply set temperature (Tset) by a second times (T2); and performing early fire extinguishing. Accordingly, the present invention can prevent deterioration of heating performance due to the early fire extinguishing.
