Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control method capable of performing an operation without relying on user's skill and experience in a thermal power generation plant including a boiler.SOLUTION: A boiler control method includes: a step of acquiring a parameter; a step of identifying a blow quantity; and a step of controlling a boiler to discharge boiler water. The step of acquiring the parameter is a step of acquiring the parameter correlating with a Cl concentration of water within the boiler. The step of identifying the blow quantity is a step of identifying the blow quantity on the basis of a function indicating a correlation between a blow quantity necessary to keep the Cl concentration of the water in the boiler to be equal to or lower than a reference value and the parameter and the parameter acquired in the acquiring step. The step of controlling the boiler to discharge the boiler water is a step of controlling the boiler to discharge the boiler water at the identified blow quantity.SELECTED DRAWING: Figure 2
