Abstract
Provided is a method for controlling a cascade boiler system, and the method includes a) operating the number of boilers set in an initial operation state, b) detecting a supply water temperature and a returned water temperature of the primary side of the hydro-separator and a supply water temperature and a returned water temperature of the secondary side, and calculating a flow rate corrected by the hydro-separator using the detected temperatures, c) calculating a set temperature serving as the supply water temperature of the primary side that is able to maintain the supply water temperature of the secondary side when the supply water temperature of the secondary side is within a set range of a target temperature while maintaining the initial operation state, and d) calculating the number of boilers that are able to maintain the calculated set temperature, and controlling an operation of the boilers according to the number.
