METHOD FOR CONTROLLING COMBUSTION OF BOILER USING TEMPERATURE SENSOR FOR SUPPLYING AND RETURING HOT WATER

摘要

The present invention relates to a method to control combustion of a boiler using a temperature sensor to supply and return hot water comprising: a step of supplying designated heating calories (X kcal) to a burner; a step of detecting a change value (Tx) of hot water supplying temperatures; a step of calculating a hot water supply setting temperature (Tsa); a step of determining whether the present hot water returning temperature (Tb) is stabilized within a designated temperature difference in a designated time; a step of calculating a hot water returning temperature difference (Ty) when the present hot water returning temperature (Tb) is stabilized; and a step of returning to the step of calculating whether the present hot water returning temperature (Tb) is stabilized if the calculated hot water returning temperature difference (Ty) is 0. Therefore, the present invention prevents unnecessary loss by supplying the required calories in accordance to the heating loads, and enables an optimal control of the heating temperature.
