  • Patent number: 11229916
    Abstract: A system for controlling an electrostatic precipitator includes a computer control system with a computer and a controller in operative communication with an electrostatic precipitator. The computer control system is operative to control performance of the electrostatic precipitator by controlling one or more of: a) a power supply that controls voltage between an electrically grounded vertical plate and a metallic wire electrode in the electrostatic precipitator; b) a first feeder valve and a second feeder valve in a hopper; and c) a power supply to an electrical coil in operative communication with a rapper.

  • Patent number: 10864527
    Abstract: The method for monitoring the signal quality of an electrostatic precipitator comprises measuring in real time at least one feature of a primary electric power sent to a transformer of the electrostatic precipitator and/or at least one feature of a secondary electric power sent to the collecting electrodes and discharge electrodes of the electrostatic precipitator, elaborating the at least a measured feature generating an information indicative of the electrostatic precipitation signal quality, providing the information.

  • 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).
