FLOW CONTROL METHOD FOR CIRCULAR PUMP IN BOILER

摘要

PURPOSE: A circulating pump flow control method of a boiler is provided to prevent too much heat from being supplied by maximizing the heating efficiency by reducing the flux of a pump if a little bit supply heat is needed and by reducing the circulation flux of the pump by recognizing the current heating load amount according to the supply heat amount. CONSTITUTION: A circulating pump flow control method of a boiler is composed of the steps of calculating the amount of heat by computing supply heat amount by the tapping temperature according to the preset temperature if burning signal is generated(S2), operating a circulating pump with maximum rotation speed(S5), and continuously detecting whether or not the heating temperature reaches the preset temperature(S6).
