Industrial boiler control method using statistical data according to combustion stage change

Abstract

Provided is an industrial boiler control method using statistical data according to changes in combustion stages. A boiler control method according to an embodiment may include: collecting operation data of each boiler with respect to a plurality of boilers; calculating an operation efficiency of each boiler based on the operation data; generating statistical data of each boiler according to changes in combustion stages from the operation data; and controlling a pressure of each boiler to optimize an objective function having the operation efficiency and the statistical data as parameters. Accordingly, efficiencies of boilers may be prevented from being degraded due to frequent changes in combustion stages for the reason of a position connected to a steam header, and ultimately, energy consumption required for operating boilers may be reduced.
