Electrostatic precipitator is a process that is used in thermal power plant to control air pollution, that is caused by flue gasses. Electrostatic precipitator has eletrode cuires that are maintained at several thousand volts which produce a corna that releases electrons are to which it removes 99% of the particulate matter but if is not able to generate high voltage of several thousands no
An electrostatic precipitator has electrode wires and a stage of collecting plates and scrubber. The electrode wires are maintained at several thousand volts, which produce a corona that releases electrons. These electrons attach to dust particles and give them a net negative charge within a very small fraction of a second. The collecting plates are grounded and attract the charged dust particles
An electrostatic precipitator in a thermal power plant is not able to generate high voltage of several thousands. Write the ecological implication because of it. It will not be able to remove particulate matter present in the exhaust of thermal power plants & hence cannot control pollution
An electrostatic precipitator removes particulates of less than 50mm size. The particulates are electrically charged and then attracted to oppositey charged plates for collection. The vvibration of these plates removes the particulate matter to the bottom and the pollutant free air then escape to
One of the major limitations of the electrostatic precipitator is that it cannot remove very small particles (less than 2.5-micrometer diameter), which causes various respiratory problems. Concept: Prevention of
(a) Two places where it is essential to install electrostatic precipitators are automobile vehicles and thermal power plants. This is so because these produce toxic gases and need an electrostatic precipitator to remove particulate matter from their exhaust. (b) One of the major limitations of the electrostatic precipitator is that it cannot remove particulate matter that are very small

Dec 11, 2013 Electrostatic precipitator- CBSE 12 BIOLOGY Electrostatic precipitator: To remove particulate matter; the most widely used of which is the electrostatic precipitator which can remove over 99 per cent particulate matter present in the exhaust from a thermal power plant
Jul 01, 2021 Step by step video & text solution for Assertion : An electrostatic precipitator (ESP) is a particulate collection device that removes dust and smoke particles from flowing air using the force of an induced electrostatic charge. br Reason : An ESP is a highly efficient device as it removes 99 percent of particulate matter present in the exhaust from a thermal power plant. by Biology experts to help you in doubts & scoring excellent marks in Class 12
Electrostatic precipitator can remove over 99% particulate matter present in exhaust from a thermal power plant. How? Ans. Electrode wire at thousand volts, produce corona to release electrons, electrons attach to dust particules giving them net negative charge, charged dust particules attracted/collected by collecting plates which are grounded
A. The thermal plants release particulate matter, which is considered very harmful for the human health. The electrostatic precipitator helps in the removal of particulate matter and can remove over 99 per cent of it present in the exhaust of the thermal power plant.It has electrode wires that are maintained at several thousand volts. These produce a corona that releases electrons
