How do chimneys in power stations work to attract soot particles?
Chimneys in power stations use electrostatic precipitator to attract soot particles. Electrostatic precipitator are filtration devices that use electromagnetic charges to remove particles from gases.
What is the full form of ETP in power plants?
Electrostatic tar precipitator
What type of pollution is minimized by electrostatic precipitator and filters in factors?
air pollution
What are the four names of applications that use electrostatic principles?
Electrostatic paint sprayer, used for the coat of paint on a car, plane, etc. Photocopier. Electrostatic precipitator, used to clean polluted air. Sorry, I only know three.
What is the voltage required for an electrostatic precipitator?
There is a lot of variation in the applied DC voltages that operate an electrostatic precipitator (ESP). Some work on a few thousand volts (a few kV), while big industrial units might run on upwards of 100,000 volts (100 kV).
Why rapping is required in emitting electrode in electrostatic precipitator?
Disloge the fly ash to give hopper bottom side..
Where to use bag filter and where to use electrostatic precipitator?
Klean Electrostatic Precipitator (ESP) can be use in all spheres which has problem in smoke. Klean ESP has two basal types. One is Commercial ESP, mainly used in commercial kitchen cooking fume's purification. The other type is Industrial ESP, used in purifying smoke or recycling wasted DOP oil in PVC production lines, such as PVC leather, PVC gloves and PVC wall paper, etc. Also stenters of textile dyeing and finishing can use our Industrial ESP to purify the smoke.
Why in a electrostatic precipitator high negative voltage given to emitting electrode where as collecting electrode is normally earthed?
electron can easily penetrate in to dust particle
How can neutral pollutant particles be made attractive to the charged plate in an electrostatic precipitator?
The positive plate attracts the negative particles to remove them from the gas.
What is typical charging time of dust particle in an Electrostatic Precipitator?
An electrostatic precipitator is a filterless gadget that eliminates fine particles, similar to residue and smoke, from a streaming gas utilizing the power of an instigated electrostatic charge insignificantly hindering the progression of gases through the unit. As opposed to wet scrubbers, which apply energy straightforwardly to the streaming liquid medium, an ESP applies energy just to the particulate matter being gathered and consequently is extremely productive in its utilization of energy (as power)
What are the disadvantages of electrostatic precipitator?
very low system resistance..get affected with load swingdependent upon electricityvery high initial cost is involvedonly handle with dry emmision
Why is DC voltage used in an electrostatic precipitator?
We use DC voltages in an electrostatic precipitator (ESP) because it is necessary to induce a charge on the particulates, and then attract them to a plate by the use of an opposite charge. An AC source would be changing constantly. That would leave our particulates picking up "different charges" at different times as they pass the plates. Further, these particulates wouldn't be attracted to the plates because the plates would be changing polarity as well. ESP's use a DC source to apply a charge of a given polarity to the particulates in the air stream, and use a plate of the opposite charge to attract and "hold" the particulates. AC sources can't do that.
