Class 12th Biology 2017 Set1 Outside Delhi Board Paper Solution
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.
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 electrons will be released and no removal of particulate matter from the exhaust.
This will lead to air pollution and may cause breathing and respiratory problems.
