Charge ratio in an electrostatic precipitator is the ratio of the amount of charge supplied to the amount of dust particles present in the gas stream. This parameter is important as it determines the efficiency of particle collection in the electrostatic precipitator. A higher charge ratio typically results in better particle collection efficiency.

How can neutral pollutant particles be made attractive to the charged plate in an electrostatic precipitator?
Neutral particles can be given a temporary charge by ionizing them using sources like corona discharge. The charged plate in an electrostatic precipitator has an opposite charge to these ionized particles, which attracts them towards the plate. This process helps to remove the particles from the air stream efficiently.
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.
Does chalk on a blackboard have an electrostatic charge?
Yes, chalk on a blackboard can acquire an electrostatic charge when written or moved on the surface, due to friction between the chalk and the board. This charge can attract or repel other objects nearby.
Which atom has the highest charge to mass ratio?
The electron has the highest charge to mass ratio. This is because it has a tiny mass compared to its charge, making its ratio very high.
In the electron charge to mass experiment if the electron is replaced by a proton or neutron would the charge to mass ratio value still be the same why or why not?
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.
How does an electrostatic precipitator work and what does it remove?
An electrostatic precipitator works by using an electric charge to remove particles like dust and smoke from the air. The device attracts the particles to metal plates, where they collect and can be removed.

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 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 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).
What is electro static precipitator esp?
An electrostatic precipitator is a device commonly used to remove fine dust particles from an airstream, or a smokestack exhaust. Often a two step process in which the unwanted particles are first given an electric charge, and then are easily attracted to a precipitate plate which carries an opposite charge. The very fines in smokestacks are an industrial problem, particularly because of their fineness, but they are then easily dealt with.
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.
How do the electrostatic smoke precipitators work?
It sucks in smoke Smoke is made up of mostly solid substances dispersed in a gas. The electrostatic smoke precipitator generates static electricity, this then gives the solid particles passing through them a negative charge. The particles then pass through to two positively charged conducting plates and, due to their negative charge, they are attracted to the plates where they collect and form a layer.
Does nylon have an electrostatic charge?
when your clothes rub against your skin an electrostatic charge is made.
How does an electrostatic precipitator work to remove particulate matter from industrial emissions?
An electrostatic precipitator uses electric charges to attract and collect particulate matter from industrial emissions. The device creates a strong electric field that charges the particles, causing them to stick to collection plates or electrodes. This process effectively removes the particles from the emissions before they are released into the atmosphere.
