  • Patent number: 9671067
    Abstract: Disclosed are a system (100) and a method (200) for being utilized in an industrial plant (10) for determining injection rate of at least one Flue Gas Conditioning Agent (FGCA) from a FGCA discharge unit (18) into a flue gas leading from a boiler (12) to be introduce into an Electrostatic Precipitator (ESP) (14) of an industrial plant (10). The system (100) and method (200) is capable of determining the optimal injection rate of the FGCA based on ESP (14) data to increase the efficiency of the ESP (14) for efficient collection of dust particles from the flue gas stream.

  • Publication number: 20160375444
    Abstract: The method for calculating the pulse firing pattern for a transformer of an electrostatic precipitator, the method comprising a) defining a target parameter indicative of the power to be supplied to collecting electrodes and discharge electrodes of the electrostatic precipitator, b) calculating a first parameter indicative of the power supplied to the collecting electrodes and discharge electrodes using the pulse firing pattern being calculated, in case one additional pulse is fired, c) calculating a second parameter indicative of the power supplied to the collecting electrodes and discharge electrodes using the pulse firing pattern being calculated, in case two additional successive pulses are not fired, d) selecting at least one pattern element on the basis of the first parameter or second parameter, e) repeating steps b), c), d), e).

  • Patent number: 8623116
    Abstract: Provided is a method of controlling the operation of an electrostatic precipitator (6) using a control strategy for a power to be applied between at least one collecting electrode (28) and at least one discharge electrode (26). 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.
