    摘要： The collection characteristics of particles entrained in a particle-laden gas for collection by an electrostatic precipitator are improved by injecting finely divided sodium and ammonium phosphate salts into a particle-laden gas stream formed by the burning of coal. Sufficient additive is injected to provide 24-1200 grams per metric ton of coal burned to form the gas. After injection, the stream is directed through a heat exchange means and finally into the precipitator to collect the particles therein.

    摘要： The separation characteristics of particles entrained in a particle-laden gas for separation by the commonly used methods for removing particles from a gas stream are improved by injecting finely divided urea into the gas stream prior to its passage through the separator. The urea conditioner agglomerates the particles to facilitate their removal from the gas stream by the separator.

    摘要： Suspended matter is removed from combustion gases containing sulfur dioxide by removing a major portion of the particulate matter from a minor portion of the gases, catalytically converting a major portion of the sulfur dioxide content of said minor portion of the gases to sulfur trioxide, mixing said minor portion of the gases with the main gas stream and subjecting the mixed gases to electrical precipitation.

    摘要： An electrostatic precipitator for removing particulates from boiler fine gas is provided. The electrostatic precipitator comprises discharge electrodes and collecting electrodes fitted in a gas passage, the electrodes being arranged in at least two electrical fields that are placed successively in relation to gas flow, and the electrical field establishing at least one electrical unit in transversal direction of said gas passage. The at least one electrical unit has the ability to be de-energised independently, separately from the other electrical units of the electrostatic precipitator. The first electrical field of the at least two electrical fields is also arranged first in the gas flow, and the first electrical field comprises more electrical units than a second field following the first field.
