Under clean and green revolution programme, an urgent need has been felt to develop mitigation devices and pollution control instruments. Through this paper, discussion has been made on pollution thrust emanating in atmosphere from stacks and its control through indigenous technology and control instruments developed in India to meet the techno-economical needs of country. Main emphasis has bee...

The role of components in an Electrostatic Precipitator (EP) for a spark and both the phenomenon and mechanism of a spark are elaborated and then the type of spark is classified by the condition of shortage between the discharge and collecting electrodes. The secondary voltage and current waveforms of a spark are discussed in order to address the severe effect of the secondary and primary curre...

Electrostatic Precipitators (ESP) are most important device used to control the pollution by collecting dust particles present on flue gases. In power plants, Coal used in Indian thermal power stations is of inferior grade, at power plant flue gas is often treated with a series of chemical process and scrubbers, having low calorific value (3500-4500)kcal/kg and high ash content due to drift ori...

Electrospray was employed upstream of an electrostatic precipitator (ESP) to enhance the collection efficiency of monodisperse nanometer-sized particles. The electrospray of deionized water produced water droplets with a size range from several tens to several hundreds μm. The visible combined effect of the ESP with the electrospray was found for the collection of particles larger than about 20...

Pulsed energization of electrostatic precipitator (ESP) may represent one of the most promising solutions to comply with strict environmental regulation in case of high resistivity dust. Performs a parametric cost comparison between conventional and pulsed ESP with reference to four main industrial areas: electric power generation, cement manufacturing, iron and steel production, glass industry...
