Method and a device for controlling the rapping of an ESP

Abstract

A method of controlling operation of an electrostatic precipitator (6) is provided wherein a soot-blowing operation is performed in an upstream device. According to the method, a signal is sent to a controller (34) that a soot-blowing operation is about to be initiated in the upstream device (2). The controller (34) is operative for controlling performance of a rapping event with respect to the electrostatic precipitator (6), and causes a rapping decision (52; 152) to be made, based on receipt of the signal. The rapping decision includes establishment of a first point in time (T1) for initiating 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 second point in time (T2) is the time at which the soot-blowing operation of upstream device (2) is initiated.
