The pulse firing pattern for a transformer of an electrostatic precipitator comprises first elements indicative of a pulse to be fired and second elements indicative of a pulse to not be fired. The pulse firing pattern further comprises couples of adjacent second elements and at least two first elements.

Pulse firing pattern for a transformer of an electrostatic precipitator and electrostatic precipitator

Disclosed are a system () and a method () for being utilized in an industrial plant () for determining injection rate of at least one Flue Gas Conditioning Agent (FGCA) from a FGCA discharge unit () into a flue gas leading from a boiler () to be introduce into an Electrostatic Precipitator (ESP) () of an industrial plant (). The system () and method () is capable of determining the optimal injection rate of the FGCA based on ESP () data to increase the efficiency of the ESP () for efficient collection of dust particles from the flue gas stream.

Flue gas conditioning system and method

Provided is a method of controlling the operation of an electrostatic precipitator () using a control strategy for a power to be applied between at least one collecting electrode () and at least one discharge electrode (). The control strategy is directed to controlling, directly or indirectly, a power range and/or a power ramping rate. As such, the temperature of a process gas is measured. When the control strategy controls a power range, a power range is selected based on the measured temperature, an upper limit value of the power range being lower at a high temperature of said process gas, than at a low temperature. When the control strategy controls a power ramping rate, a power ramping rate is selected based on the measured temperature, a power ramping rate being lower at a high process gas temperature, than at a low process gas temperature.
