Electrostatic Precipitators (ESP) are the most reliable
emission control devices that are used in coal fired power
plants to capture fine particles for reducing exhaust emission.
Its efficiency is more than 99% or more. However, capturing
submicron particles are still a problem due to complex flow
distributions and design limitations of ESP. In this study, two
different shapes of baffles inside the ESP have been considered
to assess their influence on the flow pattern using
computational fluid dynamics (CFD) code ‘ANSYS
FLUENT’.. Due to different shapes, the flow distribution will
be changed inside the ESP which is expected to affect and
increase the residence time of flue gas. The results of this
paper indicate that the proposed shapes can influence in
collecting more fine particles.
