The necessary voltage can be calculated as:
..........................(5.26)
R1 – radius of wire electrode
R2 – radius of collecting electrode
The velocity of collection for a conducting particle is given by:
...................................................(5.27)
μ - Viscosity of gas, N-s/m2
The velocity of collection for a non conducting particle is given by:
...................................................(5.28)
The collection efficiency or precipitation efficiency of a electrostatic precipitation depends upon the time for which the gas remains in active electric field. Collection efficiency is usually from 90-99% due to economic reason. The collection efficiency in terms as:
........................................................(5.29)
Where,...................... t- is time for which gas remains in electric field
..................................w- velocity of particle collection.
