摘要： PROBLEM TO BE SOLVED: To provide a water supply control method and a water supply control device of a boiler capable of being easily applied even to an existing boiler since any new control equipment is not added, and controlling the water level fluctuation of the boiler in a low load zone.SOLUTION: A water supply control device of a boiler includes a water supply flow rate calculation unit 10, a water supply pump rotation number calculation unit 20, and a water supply operation amount calculation unit 30. The water supply flow rate calculation unit 10 calculates a water supply flow rate from deviation between a water level set value and a water level measurement value. The water supply pump rotation number calculation unit 20 calculates the number of rotation of a water supply pump based on the calculated water supply flow rate and a boiler pressure measurement value. The water supply operation amount calculation unit 30 calculates a water supply operation amount from the calculated number of rotation of the water supply pump, and controls the number of rotation of the water supply pump by the operation amount.
