MODIFICATION OF DISCHARGE ELECTRODE IN ELECTROSTATIC PRECIPITATOR

R.Isaac, T.Balusamy

Abstract: In Fluidized bed boiler the exhaust gas has more ash particles due to the agro fuel. As per the Environmental control board norms the particle level from the exhaust gas should not be exceed 50ppm. But it has 700ppm. Several scientific studies have linked the ash particles with a wide range of health-related disorders resulting in daily mortality, respiratory and cardiovascular hospitalizations, adverse impaired lung function, etc. For control the dust particles the electrostatic precipitator is installed with the boiler. The electrostatic precipitator having rod type discharge electrode and collecting plate to charge and collect the dust particles. The spiked discharge electrode is used instead of rod type discharge electrode and to reduce the material cost of the electrostatic precipitator. The efficiency of the spiked discharge electrode electrostatic precipitator more compare to rod discharge electrode electrostatic precipitator. The electrical field strength of the spiked discharge electrode modeling and analyzing with help of ANSYS (Professional Emag)
