<P>PROBLEM TO BE SOLVED: To improve an EP hammering control method which controls damper open hammering and damper close hammering, and thereby to enable to reduce the power cost of a ventilation system at the time of normal operation, and to enable to efficiently operate a boiler system of coal burning. <P>SOLUTION: The electrostatic dust collection system includes: an EP ash treatment apparatus 42; a soot concentration detector 44; a timer 52; and a controller 55 which controls dust collecting electrode hammering apparatuses 24a, 24b, and 24c based on the operation condition of a boiler system of coal burning obtained from these apparatuses, the timer or the like, wherein the controller 55 controls the dust collecting electrode hammering apparatus 24a or the like to always carry out interval charge hammering, distinguishes whether the operation condition of the boiler system of coal burning corresponds to the interval charge hammering condition during the enforcement of the interval charge hammering, and controls the dust collecting electrode hammering apparatus 24a or the like to carry out damper link non-charge hammering when the operation condition of the boiler system does not correspond to the interval charge hammering condition. <P>COPYRIGHT: (C)2012,JPO&INPIT |
