    • A membrane (8) is used as a collection substrate in an electrostatic precipitator. Possible material choices include fibers in the form of woven mats, screens made from stainless steel wires or fiber reinforced polymer composite membranes. The membranes have a tensile bias (14) applied during operation, and have impulse tensile forces applied during a dust removal step. By combining a dry electrostatic precipitator membrane field with wet-film cleaning field, it may be possible to improve collection efficiencies both by reducing turbulence and eliminating re-entrainment losses due to rapping. Through implementation of new materials that resist hostile electrostatic precipitator environments, the invention enhances the possibility of using novel technologies, such as pulsed corona and others, suitable for removal of molecules such as nitrogen oxides and sulphur oxides, which is very important for meeting the proposed PM2.5 EPA emissions regulations.

    • A method for controlling an electrostatic precipitator unit, comprising discharge electrodes and collecting electrodes, between which a high voltage is maintained by a direct current supplied to the electrodes. Dust deposited on the collecting electrodes is removed by mechanical rapping of the collecting electrodes by mechanical impulses being supplied to the electrodes individually or in groups. The collecting electrodes of the precipitator unit are cleaned during recurrent, relatively short, rapping periods separated by rapping intervals, of considerably longer duration. A strategy of controlling the electrical parameters is selected and this strategy is maintained during the optimisation. The length of the interval between the rapping periods and possibly also other rapping parameters are varied. The current and voltage during the interval between the rapping periods are measured. The average ofthe current, voltage, or a quantity derived from the currrent and/or voltage, during the interval between the rapping periods, is calculated. This calculated average is used for controlling the length of the rapping intervals and/or other rapping parameters.

    • A vibrating wet precipitator is designed to remove particulates from particulate-laden hot gas. The precipitator 10 includes an array 30 of vertical wet cords 26 stretched within a duct 12. The cords 26 are tuned to vibrate due to the gas flow by controlling key parameters such as gas flow, velocity, cord length and diameter so that particulate collection and heat transfer efficiency are maximized. The cords are part of sieves 24. A plurality of these sieves are arranged to define a plurality of gaps 28, through which the exhaust flows. The sieves 24 and thus the cords 26 are spaced so that a vortex from a first cord 26(a) affects an adjacent cord 26(b) and a subsequent cord 26(c). The particles are then absorbed in liquid, which can be passed through a heat exchanger, filtered and subsequently reused. Preferably the cord arrangement is designed to allow the cords to vibrate at high frequencies, typically 10 to 100 Hz, to maximize particulate collection.

    • A method for controlling an electrostatic precipitator unit, which comprises discharge electrodes and collecting electrodes. Between the electrodes a varying high voltage is maintained by a pulsating direct current supplied thereto. Under the action of the electric field between the electrodes, the particles, charged by the current therebetween, are moved towards the collecting electrodes and deposited thereon. Dust deposited on the collecting electrodes is removed by mechanical rapping. One or more mechanical impulses are supplied to the electrodes individually or in groups in a predetermined manner. All collecting electrodes of the unit are cleaned during recurrent, relatively short, rapping periods separated by rapping intervals of essentially longer duration. During the whole rapping period or during an introductory part of the rapping period, the voltage between the electrodes is reversed in relation to the voltage between the electrodes during the intervals between the rapping periods. The frequency, pulse charge and/or pulse duration of the pulsating direct current are varied, thereby obtaining a plurality of combinations of frequency, charge and duration. An optimal combination of frequency, charge and duration is established. Amplitude and/or duration of the reversed voltage are adjusted in dependence on the pulse frequency for the established optimal combination of frequency, charge and duration.

    • The invention applies to a method for the acceleration of an electromagnetic rapper (20), particularly for an electrostatic precipitator, which comprises a metal cylinder (25) as a hammer, an electrical coil (23) for lifting the metal cylinder (25) and electrical means for energising the electrical coil (28). For cleaning a surface the metal cylinder (25) is lifted by an initial electrical pulse (4) generated by the electrical means for energising the electrical coil (28).

The invention can be implemented in a technically less extensive and expensive way compared to mechanical devices applied for the acceleration of metal cylinders of rappers.

    • A method for controlling the electrode cleaning of an electrostatic precipitator unit (1, 2, 3), comprising discharge electrodes and collecting electrodes, between which a high voltage is maintained. Dust deposited on the collecting electrodes is removed by mechanical rapping of the collecting electrodes by one or more mechanical impulses being periodically supplied to the electrodes individually or in groups in a predetermined manner. All the collecting electrodes of the unit are cleaned during recurrent, relatively short, rapping periods separated by rapping intervals of considerably longer duration. The rapping period is divided into two or more rapping cycles. During each rapping cycle essentially all the collecting electrodes are supplied at least one mechanical impulse. The voltage between the electrodes of the precipitator unit or the current supplied to the electrodes of the precipitator unit is reduced step-by-step between the rapping cycles and is kept essentially constant during each individual rapping cycle.
