How can you increase the efficiency of an electrostatic precipitator?

How can you increase the efficiency of an electrostatic precipitator?

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 does a precipitator do?

electrostatic precipitator, also called electrostatic air cleaner, a device that uses an electric charge to remove certain impurities—either solid particles or liquid droplets—from air or other gases in smokestacks and other flues.

What are factors affect the efficiency of electrostatic precipitator?

These changes result in changes in flue gas flow rate, temperature, moisture content, particle load- ing, composition, size, and size distribution. These changes in process conditions inevitably affect the ESP efficiency. Under normal conditions, the collection efficiency of an ESP is typically >99.5%.

How does ESP work in power plant?

A dry electrostatic precipitator (ESP) electrically charges the ash particles and imparts a strong electric field in the flue gas to collect and remove them. An ESP is comprised of a series of parallel, vertical metallic plates (collecting electrodes) forming lanes through which the flue gas passes.

What are the advantages and disadvantages of electrostatic precipitator?

Electrostatic Precipitators Information

Advantages Disadvantages
Handles very large gas volumes and heavy dust loads with low pressure drop. Not very flexible to changes in operating conditions once installed/purchased.
Very high collection efficiencies, even for very small particles. Cannot control gaseous emissions

What is corona power in ESP?

Corona power ratio is the ratio of power consumed in watts to the airflow in cubic feet per minute. This tells us about the energy consumed in filtering one cubic foot of air per minute. The corona power ratio affects the efficiency of an electrostatic precipitator.

What industries use precipitators?

What Industries Use Electrostatic Precipitators?

  • Cement plants.
  • Fossil fuel-fired boilers.
  • Hazardous waste incinerators.
  • Lead/zinc/copper smelters.
  • Municipal waste incinerators.
  • Petroleum refineries.
  • Power-generating stations.
  • Pulp and paper mills.

What are smoke precipitators?

Smoke precipitator is a device that removes smoke or other particles from air by using high voltage electrostatics. The smoke precipitator forces dirty flue gas between two electrodes.

What are the limitations of electrostatic precipitator?

Electrostatic precipitators have a high initial capital cost, which makes it prohibitive for small-scale industries. They are expensive to purchase and install. In addition to being costly, they require large space to be set up.

What pollutants do electrostatic precipitators remove?

Electrostatic Precipitator In Air Pollution Control They remove fine particulate matter like ash, dust, and soot from exhaust fumes. This is especially useful for power stations that rely on fossil fuels like coal or oil to generate electricity.

Is corona a discharge?

Corona Discharge (also known as the Corona Effect) is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor that is electrically charged.

What are the causes of sodium depletion?

Sodium depletion almost invariably is associated with excessive losses of sodium-containing fluid ( McKeown, 1986; Rose, 1984 ), most often occurring as the result of gastrointestinal losses through vomiting or diarrhea ( Fisher and Martinez, 1976; Lakritz et al., 1992 ).

What is SDS KCl precipitation used for?

SDS-KCl precipitation has proved useful in biological purification and protein analysis procedures. KCl or potassium acetate are employed to extract and purify SDS solubilized proteins and DNA structures (9, 16-17).

Why do potassium salts flocculate the dispersion particles of SDS?

The use of potassium salts unlike the sodium salts flocculated the dispersion particles due to precipitation reaction of potassium ions and the adsorbed SDS. Additionally the uncharged hydrocolloid polymers MC and HPMC in contrast to the ionic polymers xanthan gum and NaCMC showed incompatibility due to their interaction with SDS.

Can the KCL-SDS precipitation reaction be used for flocculation of pharmaceutical suspension?

K+- SDS interactions have proved useful in protein and DNA analysis studies and we found this precipitation reaction to be applicable in flocculation of pharmaceutical suspensions containing SDS. Key Words: KCL-SDS Precipitation Reaction, Flocculation, HPMC-SDS Interaction, Megestrol Acetate, Suspensions Introduction
