AI Technical Summary
Technical Problem
Boiler water quality destabilization due to impurity accumulation, leading to carryover, corrosion, and scale formation, which can cause accidents such as boiler bursting.
Method used
Intermittent operation of the feedwater pump, combined with intermittent discharge of boiler water through a blow pipe, controlled by electrical conductivity sensors to maintain stable water quality, and adjusting the blowing operation time based on conductivity limits.
Benefits of technology
Stabilizes boiler water quality by continuously replacing concentrated boiler water with fresh water, preventing corrosion and scale formation, thereby ensuring safe boiler operation.

Abstract
To stabilize the water quality of boiler water in a boiler, thereby preventing the generation of carry-over in which a large amount of boiler water is mixed into generated stream, corrosion of each part of a can body, and an overheat state of a heat transfer surface due to the adhesion of scale to a can wall surface.SOLUTION: A method of stabilizing the water quality of boiler water in a boiler is provided. A water supply pump for supplying the boiler water to the boiler is intermittently operated. Whenever the water supply pump is intermittently operated, blow operation for discharging the boiler water to the outside of a can is performed.SELECTED DRAWING: Figure 2
