Electrostatic Precipitator(ESPs) Efficiency Calculator
This ESPs calculator is used to measures the removal of dust and ash particles with the exhaust gases of thermal power plants.
Electrostatic Precipitator(ESPs) Efficiency Formulas
The efficiency of the electrostatic precipitator is dependent on the particle size of the aerosol (dust, mist) to be collected.The collection efficiency if high for more massive particles and low for small particles.The formula to calculate the efficiency.
η = 1 - e(-
Where,
η is fractional collection efficiency
W is terminal drift velocity in m/s
A is total collection area in m2
Q is volumetric air flow rate in m3/s
Terminal Drift Velocity : is the velocity an object attains when it falls through the air.
Total Collection Area : it denotes the entire area of the collecting plates.
Volumetric Air Flow Rate : is the volume of gas which passes per unit time.
