  • Publication number: 20100313749
    Abstract: A method of controlling the operation of an electrostatic precipitator (6), wherein a soot-blowing operation is performed in an upstream device (2), comprising the steps of: causing a signal to be sent to the effect that a soot-blowing operation is about to be initiated in said upstream device (2) to a controller (34) that is operative for controlling the performance of a rapping event with respect to the electrostatic precipitator (6), and said controller (34) causing a rapping decision (52; 152) to be made, based on the receipt thereby of said signal, said rapping decision including the establishment of a first point in time (T1) for initiating the performance of a rapping event with respect to the electrostatic precipitator (6), such that said first point in time (T1) is correlated to a second point in time (T2), the latter being the time at which the soot-blowing operation of said upstream device (2) is initiated.

  • Publication number: 20100313747
    Abstract: The disclosure relates to a method or device for controlling the operation of an electrostatic precipitator, ESP. The ESP is used to remove dust particles from a process gas, which is generated by a combustion process. An indicator signal is generated, typically by means of a temperature sensor, which signal is indicative of the temperature of combustion air, which is fed to the combustion process. The ESP is operated in a manner depending on the indicator signal. Thereby back-corona effects may be avoided to a great extent.
