The growing increase in emissions of ultrafine particles or nanoparticles by industries and urban centers has become worrisome due to the potential adverse health effects when inhaled. Particles this size range have greater ease pulmonary penetration, being able access bloodstream deposit other regions body. Thus, development optimization equipment processes aimed at removal aerosols been gaini...

One of the most important environmental protection problems for coal-fired power plants is prevention of atmospheric pollution of flying ash. The ash particles are typically removed from flue gases by means of electrostatic precipitators, for which the efficiency may be significantly increased by lowering the resistance of fly ash, which may be achieved by controlled addition of microamounts of...

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...

Flue gas conditioning (FGC) systems offer an effective option for control of Particulate Matter (PM) emissions and enhances the performance of the Electrostatic Precipitators (EPs) when using coal of different properties. The increasing environmental awareness and the mandate of the Environmental Protection Agencies (EPA) in various countries to thermal power stations using coal-fired boilers f...

The effective collection of fly ash in pulverized coal-fired plants which utilize electrostatic precipitators depends primarily on the effect of coal sulfur content, the gas temperature, and the carbonaceous content of the fly ash on the precipitator electrical power input. While the majority of precipitator installations are effective fly ash collectors, an abnormal change in any of the above ...

Due to the turbulent mixing between agglomeration agent and dust, number of collisions per unit time particles droplets increases with particle size in process chemical agglomeration, efficiency accordingly. Turbulent can promote effect subsequent by strengthening collision agglomerant droplets. The author used cooperate order improve dust removal. from removal efficiency, which greatly electri...
