    摘要: In an electrostatic precipitator for cleansing flue gases from industrial plants, comprising one or more precipitator sections powered from a separate continuous or intermittent DC-voltage electric supplies, a method and apparatus for detecting back corona, i.e. discharges in the dust layer precipitated on the collecting electrodes of an emission electrode system during the cleansing process, by making periodic upward adjustment of the precipitator current for each DC-voltage supply until spark-over occurs, and where after spark-over or a blocking of the precipitator current for a predetermined period of time if no spark-over occurs, the minimum value of the precipitator voltage is compared wtih the minimum value before the spark-over or before the blocking period, the latter minimum value being corrected by means of a predetermined sensitivity factor. In this way a measurement may be made for each single sparks-over so that the reducing effect of the spark-over on the degree of purification may be avoided at the next sparks-over.

    摘要: To control an electrostatic precipitator towards minimum energy consumption at a given efficiency the dust content in the exit air of the precipitator is measured and the efficiency of the precipitator regulated upwardly or downwardly accordingly. Regulation is carried out in accordance with a selected one of a plurality of predefined stored strategies by a central unit which controls the parameters of the independent power supplies to the precipitator sections.

    摘要: A method of operating an electrostatic precipitator (7) includes feeding the precipitator with electric power generated by a power supply (10) according to a regime adapted to impart between the precipitator electrodes a voltage having a DC component and an AC component. A control unit (8) measures the electrode voltage, establishes a voltage peak value and a voltage mean value, and computes the product of peak value by mean value to arrive at an index of expected performance (IEP). Operating set points are tuned so as to maximize this index of expected performance.

    摘要: A cement production plant and method of regulating the flue gas temperature in a cement production plant. The cement production plant includes a kiln, a flue gas conditioning device, a mill and an electrostatic precipitator. The flue gas from the kiln is passed through the conditioning device. From there, the flue gas is conveyed either via the mill or directly to the electrostatic precipitator. The measurements are carried out in the flow path of the gas of the flue gas temperature before the electrostatic precipitator, and the water is supplied to the flue gas for cooling purposes in the conditioning device as a response to this temperature measurement, provided the temperature is too elevated.
