What is ESP in environmental science?

What is ESP in environmental science?

Description. An electrostatic precipitator (ESP) removes particles from a gas stream by using electrical energy to charge particles either positively or negatively. The charged particles are then attracted to collector plates carrying the opposite charge.

What does ESP stand for in dust collection?

An electrostatic precipitator (ESP) is a filterless device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.

What is ESP structure?

An ESP is comprised of a series of parallel, vertical metallic plates (collecting electrodes) forming lanes through which the flue gas passes. Centered between the collecting electrodes are discharge electrodes which provide the particle charging and electric field.

What is ESP filtration?

ESP is an air filtering device that uses electrostatic charge to remove dust particles. ESP ionizes the air by applying high voltage to the electrodes. Dust particles are charged by the ionized air and collected on the oppositely charged collecting plates.

What are the uses of ESP?

The electronic stability program (ESP®) supports the driver in nearly all critical driving situations. It comprises the functions of the antilock braking system (ABS) and the traction control system, but can do considerably more. It detects vehicle skidding movements, and actively counteracts them.

What is the capacity of ESP?

Electrostatic Precipitator, Capacity: 10 To 600 MW

What is full form of ESP?

extrasensory perception: perception or communication outside of normal sensory capability, as in telepathy and clairvoyance.

Why is ESP called a static precipitator?

What Does Electrostatic Precipitator (ESP) Mean? An electrostatic precipitator (ESP) is a device which removes dust or other finely divided particles from a gas by charging the particles inductively with an electric field, then attracting them to highly charged collector plates.

What is the function of ESP in coal fired power plant?

In a coal-fired power plant, using the force of an induced electrostatic charge, an electrostatic precipitator (ESP) is used to remove ash, dust and smoke from flue gas so it does not pass into the atmosphere. Accurate measurements of the primary electrostatic transformer current are necessary to keep a stable process.

What is the characteristics of ESP?

1. Absolute characteristics: a) ESP is designed to meet specific needs of the learner; b) ESP makes use of the underlying methodology and activities of the disciplines it serves; and c) ESP is centred on the language (grammar, lexis, register), skills, discourse and genres appropriate to these activities. 2.

How do you calculate ESP efficiency?

The overall collection efficiency of an ESP is given by the famous Deustsch Anderson equation.

1. where, f = specific collection area of the electrode.
2. and Ud = average migration velocity of the charges dust particles towards the collection electrode.

What are the advantages of ESP?

Advantages of electrostatic precipitator:

• The durability of the ESP is high.
• It can be used for the collection of both dry and wet impurities.
• It has low operating costs.
• The collection efficiency of the device is high even for small particles.
• It can handle large gas volumes and heavy dust loads at low pressures.

Does an electrostatic precipitator remove co2?

Electrostatic precipitators or (ESP) will take the soot, ashes, and unburned carbon dioxide from smoke through an electric charge and emit clean air or smoke into the atmosphere. Extraction of these harmful products is very important as pollutants can cause serious damage to buildings, environment, and human health.

What is ESP and its types?

ESP is basically divided into two types: EOP (English for Occupational Purposes) and EAP (English for Academic Purposes).

What is the importance of ESP?

The ESP approach enhances the relevance of what the students are learning and enables them to use the English they know to learn even more English, since their interest in their field will motivate them to interact with speakers and texts.

What is ESP efficiency?

The collection efficiency of the ESP is related to only corona power irregardless of the gas temperature. To increase the resistivity of the oil dust, the technology is used that the ammonia is injected into the ESP inlet gas, and ammonium sulfate with a high-resistivity matter is produced.

What is ESP collection efficiency?

The collection efficiency of ESP approaches to 99% in most of the cases but the efficiency comes down with higher fraction of fine particles compared to coarser particle (Kim et al. 2010). The overall mass based collection efficiency of ESPs exceed 99%.

What is ESP and what are its purposes?

English for Specific Purposes (ESP) is a language approach whose goal is to provide learners with narrowly defined goals the language elements they need to function as professionals.

Are electrostatic precipitators environmentally friendly?

Yes. The electrostatic precipitator is an air purification tool. Once the particles are collected onto collection plates, they are disposed of in an environmentally-friendly manner, keeping the pollutants from entering the atmosphere.

What are the three branches of ESP?

In the ‘Tree of ELT’ (Hutchinson & Waters, 1987), ESP is broken down into three branches: a) English for Science and Technology (EST), b) English for Business and Economics (EBE), and c) English for Social Studies (ESS).

What are characteristics of ESP?

What are the three features common to ESP?

The characteristics of ESP courses identified by Carter (1983) are discussed here. He states that there are three features common to ESP courses: a) authentic material, b) purpose-related orientation, and c) self-direction.

How can we improve ESP efficiency?

The most common methods of improving an electrostatic precipitator are:

1. Upgrading the collection electrodes.
2. Upgrading the discharge electrodes.
3. Upgrading the rapping system.
4. Upgrading the transformer-rectifier assemblies.
5. Improving the flow distribution.

What is the main purpose of ESP materials?

The purpose of materials in ESP

Materials are used to stimulate and support language instruction and their design and/or adaptation is an important element of ESP teaching practice.

What are the disadvantages of electrostatic precipitator?
