Particle precipitation efficiency in an electrostatic precipitator

Journal of Electrostatics, 2005
Abstract In this paper, results of the measurements of the size distribution of seed particles after their precipitation in a wire-plate-type ESP with seven wire electrodes are presented. The cigarette smoke was used as a source of seed particles. The particles of sizes from 0.5 to 8 μm were counted in the 0.5 μm-wide ranges at the ESP outlet using a

Calculating Collection Efficiencies for Electrostatic Precipitators

Journal of the Air Pollution Control Association, 1975
The body of information presented In this paper is directed to those Individuals involved In research on, or the design of, electrostatic precipitators. A model for calculating collection efficiencies— one based solely on physical principles and, as a result, one requiring no prior Information from pilot plant or field testing—has been employed to ...

PRECIPITATION EFFICIENCY OF CYCLONIC STORMS∗

Annals of the Association of American Geographers, 1978
ABSTRACT Precipitation efficiency is a single parameter for estimating the precipitation production ability of atmospheric moisture release mechanisms. Analysis of twenty cyclonic storms occurring in the eastern United States revealed distinct precipitation efficiency patterns with highest efficiency occurring in the cold sectors and at the cold fronts.

Efficient Modelling of Asphaltene Precipitation

SPE Annual Technical Conference and Exhibition, 1993
AbstractAn efficient modelling technique based on the representation of the precipitated asphaltene as a pure dense phase is presented. The success of the approach is based on the division of the heaviest component in the oil into a non-precipitating and a precipitating component. The characterization of these components is discussed.

Enhanced precipitation efficiency of electrostatic precipitators by means of impulse energization

Conference Record of the 1988 IEEE Industry Applications Society Annual Meeting, 1991
To assess the benefits of impulse energization with different coals, experimental industrial research was performed at a 70 MWe thermal power plant. Two technologies for impulse power supplies were tested over 10000 h of operation. The results of the tests, performed according to ASME standards, demonstrated that impulse energization has great ...

Upgrading of existing precipitator efficiencies

1997
With the ever-increasing legislative pressures to reduce discharges from all sources, the owner/operator of a specific process plant fitted with an electrostatic precipitator, or any form of particulate collection system, is faced with the dilemma as to how to improve the performance of his particular plant to comply with these changes of emission ...

Prediction of the cleaning efficiency of an electrostatic precipitator

Journal of Electrostatics, 2002
Abstract The optimisation of the cleaning efficiency of electrostatic precipitators is important in a wide range of industrial applications. The present paper describes the development and assessment of a complete design and optimisation method, that takes into account the flow, particle, and electric-field properties.

Precipitator efficiency for log-normal distributions

Atmospheric Environment (1967), 1982
Abstract The work of Allander and Matts with its subsequent continuation by Matts and Ohnfeldt, on the efficiency of electrostatic precipitation for polydispersed particles, has attracted a certain amount of interest in recent years because of its actual and potential usefulness.

Efficient extraction of Rb+ and Cs+ by a precipitation flotation process with ammonium phosphowolframate as precipitant

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2021
Abstract The properties of a precipitation flotation process for Rb+ and Cs+ extraction from the aqueous solutions are investigated using ammonium phosphowolframate (AWP) as the precipitating agent and cetyltrimethylammonium bromide (CTAB) as the collector and foaming agent in this research. Different parameters including precipitation reaction time,
