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 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.
What is thermal voltage?
In semiconductors, the relationship between the flow of electrical current and electrostatic potential across a p-n junction depends on a characteristic voltage called the thermal voltage, denoted VT.
What will happen if current is more than required in diode?
If the applied voltage is greater than maximum forward voltage, the diode will get damaged..
How much voltage is required to force 3 amperes through a resistance of 36 ohms?
The voltage is 3 x 36 or 108 volts.
What are 3 things required to induce voltage?
A magnetic field, a conductor and movement.
Why rapping is required in emitting electrode in electrostatic precipitator?
Disloge the fly ash to give hopper bottom side..
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
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
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 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.
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
How does a electrostatic precipator work?
an electrostatic precipitator is a device in which a dusty air stream is passed through some plates carrying a high voltage. This adds an electric charge to the dust particles. When the air stream then passes close to some plates that are grounded, then the charges attract the dust to the plates, and the dust is captured for disposal.Some furnace processes create a lot of fly ash, and the above device is typically used to capture the dust.
Electro Static Precipitator What is the effect of moisture in dust particles on efficiency of electro static presipitator?
When moisture in dust particle its is late to ionise the gas as it was dry, so gas late to Ionise meanwhile gas accumulation treatment times fail. So the electrostatic precipitator lass efficient during this.
