PROBLEM TO BE SOLVED: To provide a heating deaeration system for a boiler which has high energy efficiency and reduces fuel consumption by efficiently recovering heat from high-temperature blow water and efficiently heating and deaerating the water to be supplied, and to provide a method of controlling the amount of water to be supplied.SOLUTION: The heating deaeration system comprises a flow rate adjustment mechanism 2 for controlling water to be supplied to a boiler 1, a deaeration mechanism 4 for the water to be supplied, and a blowing heat exchanger 3 disposed upstream of the deaeration mechanism 4 for performing heat exchange between the water to be supplied and blowing discharged water. The flow rate adjustment mechanism 2 comprises a first water supply means 2a which supplies raw water of the supply water to the deaeration mechanism 4, and a second water supply means 2b which supplies water from the deaeration mechanism 4 to the boiler 1. The supply water supplied with pressure by the first water supply means 2a and heated by blowing heat exchanger 3 is supplied to the deaeration mechanism 4. The water deaerated by the deaeration mechanism 4 is supplied to the boiler 1 by the second water supply means 2b. |
