Abstract
The fuel change from oil to coal in industry has made coal combustion fly ash pollution and handling one of the most urgent problems requiring solution. In this paper which concerns coal combustion fly ash pollution, the problem of the design of electrostatic precipitators and bag filters is fundamentally and systematically discussed. Wherein, in order to fill the gap between powder properties under consideration and the design of electrostatic precipitators and bag filters, a new concept of the compression operating line is introduced and applied in combination with the statistical powder yield model presented by the authors, which has been experimentally checked using about 30 kinds of industrial powders.
The new estimation method for the powder yield locus of the deposited dust layer in electrostatic precipitators and bag filters is illustrated by example to the design of these units. The features of this design problem are considered to be similar to that of other chemical engineering plants such as distillation and absorption towers.
